The Point of Christianity in society/Ethical point of Religion

 The Point of Christianity in society

By Rony

Intrinsic religiosity = religion as an end in itself (internalized commitment).

Extrinsic religiosity = religion used instrumentally (status, community, security, etc.).

The intrinsic/extrinsic framework is classically meta-analyzed and repeatedly shown to predict opposite patterns on prejudice-type outcomes (intrinsic tends to be weaker/conditional; extrinsic often tracks social-conformity prejudice).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Researchers do not “measure Christianity” directly; they measure dimensions of religious involvement (beliefs, practices, identity strength, coping styles, etc.), and those choices change what you find. A classic example is the intrinsic–extrinsic distinction: intrinsic religiosity is closer to “living the religion as an end,” whereas extrinsic religiosity is closer to “using religion as a means” (G. W. Allport & J. M. Ross, 1967, JPSP 5(4):432–443; M. J. Donahue, 1985, JPSP 48(2):400–419). In Donahue’s meta-analysis, the headline pattern was blunt: extrinsic religiosity tended to correlate with “negatively evaluated characteristics,” while intrinsic religiosity more often tracked religious commitment and sometimes more socially desirable outcomes (Donahue 1985, pp. 400–419). Here is the kind of wording meta-analyses actually use (and this is why it matters): “Extrinsic religiousness tends to be positively correlated with negatively evaluated characteristics” (Donahue 1985, p. 400). The take-away is not “religion causes X,” but “different kinds of religiosity relate to different outcomes,” so collapsing everything into one “religiosity” score often produces muddy, contradictory results. 

Measurement tools also matter because many studies mix institutional religion (attendance, membership, participation) with more personal spirituality (private prayer, spiritual experiences, meaning/peace), and those do not behave identically. In health research, one widely used brief instrument is the Duke University Religion Index (DUREL), which explicitly separates organizational activity, non-organizational activity, and intrinsic religiosity (H. G. Koenig & Büssing, 2010, Religions 1(1):78–85). Another widely used approach is the Centrality of Religiosity Scale (CRS), built to capture how central religious meanings are, across multiple “core dimensions” (S. Huber, 2012, Religions 3(3):710–724). A practical implication is that “attendance effects” can look different from “belief effects,” because attendance bundles social networks, norms, and accountability in a way that private belief does not. This measurement issue is so pervasive that measurement-focused reviews in religion-and-health explicitly warn that mixing constructs (or using vague single-item measures) can overstate or understate associations and hide important subgroup differences (D. E. Hall et al., 2008, Annals of Behavioral Medicine context/review). 

Because you asked for “intrinsic vs extrinsic” specifically: in the prejudice and discrimination literature, intrinsic religiosity is not a magic shield, and extrinsic religiosity is not automatically “bad,” but the pattern is often directionally predictable once authoritarianism/fundamentalism and social identity are accounted for. For example, models that explicitly test mediators commonly find that the religiosity → prejudice link is largely carried by variables like right-wing authoritarianism and religious fundamentalism (M. K. Johnson, 2011, Personality and Individual Differences 50:1283–1288). That is consistent with meta-analytic work showing that “religiosity” is not one psychological thing; it can reflect moral community, social conformity, or strong ingroup boundary-making depending on what you measure (Donahue 1985, pp. 400–419; Johnson 2011, pp. 1283–1288). So if someone says “religiosity predicts prejudice” or “religiosity predicts compassion,” the first question is: which form of religiosity, measured how, in which context?

Across criminology, the most-cited quantitative synthesis is the meta-analysis concluding that religious beliefs/behaviors exert a moderate deterrent effect on criminal behavior (C. J. Baier & B. E. Wright, 2001, Journal of Research in Crime and Delinquency 38(1):3–21). That does not mean “religion eliminates crime”; it means that, averaged across studies, higher religious involvement is associated with lower offending, with meaningful heterogeneity by measurement, sample, and context (Baier & Wright 2001, pp. 3–21). In adolescent samples specifically, a later meta-analysis again finds a statistically reliable (but not huge) negative association between religion and delinquency/drug use (P. E. Kelly et al., 2015, Criminal Justice and Behavior 42(5):505–525). A separate adolescent-focused meta-analysis similarly reports that religious involvement relates positively to “constructive behavior” and negatively to “destructive behavior,” with stronger links for some dimensions than others (C. Cheung & J. W. Yeung, 2011, Journal of Adolescence 34:1059–1070). The honest bottom line: the protective association is real in many datasets, but it is not so large that it overwhelms major drivers like poverty exposure, peer delinquency, or substance availability; it’s “one factor among many,” not a force field. 

Interpersonal violence is a place where people often assume religion is either purely protective (“thou shalt not kill”) or purely dangerous (“holy war”), but large synthesis work shows a mixed pattern that depends on the violence type. A recent systematic review and meta-analysis found that higher religiosity/spirituality was associated with decreased physical and sexual aggression, but not with domestic violence overall (J. P. de Bernardin Goncalves et al., 2023, systematic review: 67 studies; meta-analysis: 43 studies). The paper’s own conclusion is very explicit: “There is an inverse relationship between R/S and physical and sexual aggression… However, these results were not observed for domestic violence.” (Goncalves et al. 2023, Conclusion section). That “domestic violence exception” matters because it fits what practitioners see: religious communities can deter some aggressive behaviors via norms and supervision, while simultaneously reinforcing staying, submission, or silence in abusive relationships when teachings are interpreted through patriarchal or “family preservation at all costs” lenses. If you’re trying to understand Christianity specifically, you have to separate community-level protective effects from theological/authority dynamics that can trap victims or excuse perpetrators in intimate contexts. 

On substance use, large-scale syntheses tend to find that religious involvement is associated with lower use, though the size and consistency vary with age, country, and whether the study measures affiliation, attendance, or personal devotion. One systematic review summarized 105 studies (1997–2006) and reported that a majority show inverse associations between religiosity/spirituality and substance use, while repeatedly emphasizing heterogeneity in design and measures (D. D. Chitwood et al., 2008, Journal of Drug Issues 38:653–688). Meanwhile, newer primary studies sometimes find nuance that frustrates simplistic narratives—for example, in some contexts, mere “attendance” is weak unless paired with genuine integration into a moral community, and some “mixed engagement” patterns can be risk markers rather than protective (M. Buchtova et al., 2020, adolescent health-risk behavior findings). And there are explicitly Christian-focused adolescent findings (e.g., Macau) reporting a strong inverse association between Christian religiosity and substance use frequency even in a minority-Christian context (S. D. Li et al., 2022, International Journal of Environmental Research and Public Health 19(18):11233). The tightest synthesis-level summary you can defend is: religious involvement often correlates with lower substance use, but you should not assume it is uniformly protective in every subgroup or that the relationship is causal in every design.

On war and large-scale intergroup conflict, the strongest “big picture” evidence in psychology does not say “religion automatically causes violence,” but it does show how religion can amplify conflict under specific conditions. A cross-societal project introduced the concept of “religious infusion” (how much religion is embedded in group identity/public life) and found it predicts multiple forms of intergroup conflict, including prejudice, discrimination, and collective violence; critically, it also interacts with mechanisms like value incompatibility and resource-power differentials (S. L. Neuberg et al., 2014, Psychological Science, published findings summarized via PubMed/DOI). The study’s “tell it like it is” line is that religious infusion can increase willingness of weak groups to endure costly confrontation—i.e., it can help make fighting feel worth it even when it’s objectively risky. That is why many modern conflict researchers treat religion less as a single “cause” and more as an identity/commitment technology that can be mobilized toward peace or war depending on elite incentives and perceived threats. Reviews of quantitative work on “interreligious peace” similarly conclude that religious ideas can foster or hinder peace “depending on their content” and that “religious identities mostly have negative effects” unless mediated by other conditions (J. Kobrich, 2023, quantitative literature review PDF). This is not theology; it’s the empirical claim that identity-boundary dynamics—and the content elites attach to them—predict outcomes. 

In the civil war and “religion and armed conflict” literature, the repeated pattern is again conditionality: religious cleavages/structures can raise mobilization capacity, harden commitments, and complicate negotiation—but the direction and strength depend on political context and resource competition. A widely cited political science working paper frames the link via mechanisms like “mobilization” (politicizing identities) and warns that quantitative studies often oversimplify measurement (M. Basedau et al., 2011, working paper). Related work argues that religion’s role in civil wars has increased over time and proposes elite “outbidding” mechanisms for why conflicts with religious stakes can escalate (M. D. Toft, 2006, Belfer Center working paper). And more recent literature reviews that are explicitly post-2000 and quantitative find enough evidence to reject claims like “religion is irrelevant,” while still insisting that content and context dominate the direction of effects (Köbrich 2023 review). The hard truth is: the empirical literature does not support either extreme slogan (“religion is the root of all war” or “religion has nothing to do with war”). It supports a third, less emotionally satisfying position: religion is one powerful identity domain that can be instrumentally and sincerely mobilized into either escalation or restraint. 

On political violence in contemporary democracies (including the U.S.), the fastest-growing “Christianity and violence” subfield isn’t about church attendance—it’s about Christian nationalism as a political identity. In a 2025 report, the Public Religion Research Institute finds agreement with political violence is substantially higher among Christian nationalism “Adherents” than among “Rejecters,” and the pattern is visible both nationally and across states (PRRI 2025 report, PDF). Academic work is now testing whether this identity is linked not only to attitudes but also to real-world violence outcomes; for example, one study examines whether Christian nationalism is connected to physical violence against religious minorities (N. Saiya, 2025, Scientific Study of Religion paper PDF). There is also active discussion of how apocalypticism/outgroup hate may interact with Christian nationalist beliefs in predicting endorsement of violence (J. A. Piazza, 2026, journal article). Separately, a large meta-analysis on predictors of political violence outcomes among young people synthesizes risk factors across many studies internationally, underscoring that “political violence” has multi-factor roots and no single-profile explanation (S. Jahnke et al., 2022, meta-analysis). Here “tell it like it is” means: the best evidence points to ideological identity packages and social threat narratives—not generic religious belief—as the moving parts most tied to violence endorsement.

On racism, one of the most cited quantitative syntheses is a meta-analytic review of “religious racism” in the U.S., which argues that part of the religion–racism link reflects intergroup dynamics (strong religious ingroup identity correlated with derogation of racial outgroups) (D. E. Hall et al., 2010, Personality and Social Psychology Review, PDF). The same paper explicitly treats “religiosity” as multi-dimensional and finds that different orientations have different implications: motives tied to conformity/ingroupness look different from motives tied to humanitarian values or agnostic questioning (Hall et al. 2010, pp. 126–139). In other words, “religion” here is not a single moral force; it’s also an identity system, and identity systems predict boundary drawing. The paper even frames the problem in social terms, quoting the idea that American religious life can be segregated—then tries to explain which psychological motives are doing the work (Hall et al. 2010, pp. 126–139). If you try to use these findings to score points (“Christianity = racist” or “Christianity = anti-racist”), you miss the mechanism: measured religiosity predicts prejudice most reliably when it tracks rigid ingroup identity and social dominance dynamics, not when it tracks compassion toward outgroups. 

On LGBTQ-related prejudice, a major meta-analysis examined multiple forms of religiosity and attitudes toward lesbians and gay men, and it finds that the relationships vary by dimension—fundamentalism and higher religious involvement measures often associate with more negative attitudes, while “quest” orientation tends to associate with greater tolerance (B. E. Whitley Jr., 2009, International Journal for the Psychology of Religion 19:21–38). This is one place where people sometimes assume “intrinsic religiosity = tolerant,” but real-world data don’t let you simplify that far; the empirical pattern depends on which doctrines, authority structures, and threat perceptions dominate a community’s moral boundary-making. Experimental work triangulates from a different angle by asking whether making religion salient causes more prejudice; a meta-analysis across experimental “religious priming” studies finds a statistically significant but small effect (roughly r≈.06) indicating that priming theistic religious concepts can increase prejudice toward outgroups in lab settings (A. Snell et al., 2022, meta-analysis PDF). That small effect matters because it is consistent with “parochial altruism” theories: religion can increase warmth toward insiders while increasing suspicion or moral condemnation toward outsiders under some primes. But it is also small enough that you should not treat it as deterministic or socially inevitable; it is one causal nudge among many. 

On gender inequality and sexism, recent synthesis work focuses on “ambivalent sexism,” which includes both hostile sexism and “benevolent” sexism (patronizing attitudes that still reinforce traditional roles). A systematic review and meta-analysis reports that religiosity shows positive correlations with ambivalent sexism, often stronger for benevolent sexism, and in some datasets extrinsic religiosity correlates more strongly with both forms than intrinsic religiosity (M. Sobiecki et al., 2024, systematic review/meta-analysis; open-access). This matters for Christianity because “benevolent sexism” often aligns with the rhetoric of “different roles, equal value,” which can feel caring at the interpersonal level while still sustaining structural inequality. Importantly, the review’s tables show this pattern appearing even in relatively secular contexts, suggesting it’s not just a function of “highly religious theocracies,” but can show up as a general cultural package linking religiosity and traditional gender roles (Sobiecki et al. 2024). That does not mean religious women (or men) are uniformly sexist; it means that, statistically, religiosity tends to correlate with endorsement of traditional gender-role beliefs in many samples. If you care about discrimination outcomes, this is a key “where religion can harm” domain, because role ideology can translate into voting behavior, workplace judgments, and tolerance for inequality even while people report sincere love and goodwill.

The prosociality literature is one of the most misunderstood because it supports both “religion helps people be generous” and “religion helps people favor insiders.” A major meta-analysis of religious priming and prosociality reports a positive prosociality effect (and, in some analyses, larger effects among believers), though it also discusses demand characteristics and publication bias as ongoing concerns (A. F. Shariff et al., 2016, meta-analysis PDF). The point here is not that Christians give more because they’re Christians; it’s that making moralizing religious concepts salient can, in experimental settings, nudge prosocial responding—especially when the participant already treats those concepts as authoritative. At the observational level, a global-oriented meta-analysis/review on religiosity and generosity argues that relationships between religiosity/spirituality and giving are real but depend heavily on level of analysis (individual, institution, national context) and on what counts as “generosity” (P. S. Herzog et al., 2020, Religions 11:446). Separate meta-analytic work on life satisfaction finds positive associations between religiosity/spirituality and life satisfaction across large datasets, with spirituality often showing stronger correlations than institutional religiosity (D. B. Yaden et al., 2022, meta-analysis; effect sizes reported in abstract). Put plainly: religion is often tied to social support, meaning systems, and norms of giving, which can lift well-being and prosocial behavior—but that same machinery can be parochial (more for “us” than for “them”). 

Economic and behavioral experiments add another layer: religious identity cues can change cooperation patterns, but not in one uniform direction across traditions. A large experimental economics synthesis argues that priming religion changes economic choices and that effects can differ by religious group (e.g., in some settings, Protestants and Catholics shift in different directions on public goods contributions) (D. J. Benjamin et al., 2016, open-access review paper). Meanwhile, the broader “trust game” meta-analysis literature shows trust and reciprocity are sensitive to study protocols and culture—meaning you cannot interpret a single “religion → trust” result as universal (N. D. Johnson & Mislin, 2011, trust game meta-analysis overview). Reviews of “religious signaling” similarly emphasize that religious practice often functions as a signal of trustworthiness and commitment, which can increase cooperation—especially inside communities where those signals are legible and valued (S. B. Northover, 2024, review). The consistent, unsentimental finding across these lines is: religion can increase cooperation within groups and sometimes generosity in general, but you must test whether the beneficiary is an ingroup member or an outgroup member, because that’s where the moral boundary often shows up.

On depression and anxiety, large meta-analyses typically find small protective associations, not dramatic ones. A major meta-analysis across 147 investigations reports that religiousness is mildly associated with fewer depressive symptoms (T. B. Smith et al., 2003, Psychological Bulletin 129:614–636). A newer meta-analysis on religiosity and anxiety similarly concludes a statistically significant relationship consistent with “buffering/coping mechanisms,” again with the implication that effect sizes are not huge and are heterogeneous (A. M. Abdel-Khalek, 2019, meta-analysis). Prospective (longitudinal) systematic reviews, which are harder to dismiss as pure reverse causation, still report mixed findings: a systematic review of prospective studies on religion/spirituality and depression finds a broad pattern of inverse associations but emphasizes variation by measurement and population (A. W. Braam et al., 2019, systematic review). Longitudinal meta-analysis work frames the causal claim even more cautiously—there is evidence for a positive effect of religion/spirituality on mental health, but the average effect is small (B. Garssen et al., 2021, meta-analysis). The “tell it like it is” conclusion is that religion is neither a guaranteed mental-health tool nor a mental-health toxin; it’s a context-dependent resource and stressor bundle with modest average effects. 

A repeated mechanism across mental health research is religious coping, and here the best evidence clearly distinguishes “positive” from “negative” religious coping. A meta-analysis of situation-specific religious coping finds that positive religious coping aligns with better psychological adjustment to stress and negative religious coping aligns with worse adjustment (G. G. Ano & Vasconcelles, 2005, Journal of Clinical Psychology 61:461–480). During COVID-19, a meta-analytic review finds that relying on religious coping in a rigid or exclusive way is not automatically protective and that the sign and size of associations depend on coping dimension and moderators (C. Cheng & Ying, 2023, meta-analysis; open-access). A broader systematic review of religiousness in the first year of COVID-19 similarly concludes that religiousness showed “both unique benefits and challenges,” not a one-way benefit (A. B. David et al., 2023, systematic review). And when psychotherapy explicitly integrates religion/spirituality, a multi-level meta-analysis of randomized controlled trials reports that religion/spirituality-based therapies can be more effective than non-R/S treatments in some comparisons, with the usual caveat that “what works” depends on fit with the patient and the intervention quality (A. J. Bouwhuis-Van Keulen et al., 2024, meta-analysis of RCTs). If you want one clean rule from all this: religion helps mental health when it functions as meaning, community, and adaptive coping; it harms when it turns into shame, threat systems, or “God is punishing/abandoning me” narratives (Ano & Vasconcelles 2005; David 2023). 

On suicide and self-harm, meta-analytic evidence often finds a protective association, while still warning that not all forms of religiosity are protective (especially when religious struggle is present). A meta-analysis reports inverse associations between religion and suicidal ideation, plans, attempts, and suicide death, describing reductions in risk estimates across outcomes (J. Poorolajal et al., 2022, meta-analysis). Applied summaries for clinicians (e.g., a U.S. Department of Veterans Affairs “From Science to Practice” brief) similarly characterize religion/spirituality as often protective while cautioning that risks and mechanisms vary (VA brief, 2024). The best way to interpret this, without propaganda, is: many religions embed moral objections to suicide, provide social support, and reduce some high-risk behaviors (especially substance misuse), which plausibly reduces suicide risk—but these pathways can break when religion becomes a site of rejection, fear, or despair. Also, suicide research is especially vulnerable to confounding (health selection into attendance) and measurement issues (e.g., stigma may suppress reporting), so associations can be real while still not proving causation. If you’re trying to use this literature for apologetics or for anti-religious polemics, you will misread it; the empirical line is again conditional and mechanism-based.

On mortality and physical health, the literature is large enough that it has multiple meta-analyses and systematic quantitative reviews—yet the best ones still emphasize modest effects and confounding risks. A widely cited meta-analysis of 42 samples reports that religious involvement is associated with lower mortality (odds ratio reported; heterogeneity tested; publication bias assessed) (M. E. McCullough et al., 2000, Health Psychology 19(3):211–222). A systematic quantitative review similarly reports a protective association between religiosity/spirituality and mortality in initially healthy populations (e.g., hazard ratio estimates around 0.82 in that synthesis), while finding weaker/null effects in diseased populations and warning about publication bias (Y. Chida et al., 2009, Psychotherapy and Psychosomatics 78(2):81–90). Large cohort work in the U.S. continues to report strong associations between frequent service attendance and lower mortality risk—while still acknowledging controversy and critique about methods and causal interpretation (S. Li et al., 2016, JAMA Internal Medicine article; and discussion of critiques in the same context). In cardiovascular disease specifically, systematic review/meta-analysis work reports mixed but often favorable associations of religious/spiritual interventions or R/S indicators with outcomes, alongside repeated calls for better measurement and design (R. Hemmati et al., 2019, meta-analysis; L. P. C. Brewer et al., 2022, scientific statement/review). The honest conclusion: there’s enough signal here that major medical journals publish it, but there’s also enough methodological noise that you cannot responsibly claim “religion causes longevity” without careful causal inference. 

In cancer and serious illness, meta-analyses typically find that religion/spirituality is modestly associated with better psychosocial outcomes (e.g., social health, coping, distress), but the field is messy because measures and interventions vary wildly. A meta-analytic review focusing on “social health” among cancer patients concludes that several R/S dimensions show modest associations with maintaining satisfying social roles and relationships, while calling for stronger research on mechanisms and timing (A. C. Sherman et al., 2015, meta-analysis). A separate meta-analytic approach on religion/spirituality and mental health in cancer underscores heterogeneity of measures and correspondingly inconsistent results—meaning “some benefit” does not translate cleanly into “always beneficial” (J. M. Salsman et al., 2015). An umbrella review in cancer care explicitly notes that the literature contains positive, mixed, and occasionally adverse associations, and argues that part of the inconsistency stems from conceptual and measurement problems in how R/S is assessed and implemented clinically (E. P. Kelly et al., 2022, umbrella review). And meta-analysis of “spiritual interventions” in oncology suggests some interventions can improve outcomes, but—again—quality, design, and intervention type matter (N. Izgu et al., meta-analysis). If you want a defensible one-liner: spirituality is often a psychological and social resource in illness, but bad measurement and bad theology-in-practice can turn it into distress rather than support. 

In marriage and parenting, the best-known synthesis is a meta-analytic review of 94 studies on religion and marital/parental functioning. It concludes that greater religiousness appears to decrease divorce risk and facilitate marital functioning, but the effects are small, and it also reports that greater Christian conservatism is modestly associated with greater endorsement and use of corporal punishment with preadolescents (A. Mahoney et al., 2001, Journal of Family Psychology). Longitudinal divorce-risk work similarly finds that multiple dimensions of religious involvement relate to marital dissolution risk, emphasizing that “religion” is multi-dimensional and should not be reduced to one attendance item (M. L. Vaaler et al., 2009, divorce-risk study PDF). More recent demographic work indicates that religious context (e.g., how secular the surrounding municipality is) can moderate how strongly “high religiosity” predicts dissolution (W. R. J. Vermeulen et al., 2023, demographic study). Systematic reviews focused on parenting practices also conclude that associations exist, but differ by belief content and practice type—again pushing away from simplistic claims like “religious families are always healthier” (E. G. Rich et al., 2024, systematic review). A faithful reading of this literature supports two statements at once: religion can stabilize families and add meaning to relationships, and certain conservative subcultural packages can increase endorsement of harsh discipline and traditional-role patterns that carry their own risks.
