Homosexuality

Intro

What does the Bible actually say about same-sex relationships? This is one of the hardest questions a Christian gets asked today, and it touches real people, families, and friendships. So it deserves a careful answer, not a slogan.

The historic Christian position is that sex belongs inside a male-female marriage, and that same-sex sexual acts fall outside that pattern. That position is held by Catholic, Orthodox, and historic Protestant churches, and it has been the consistent reading of Scripture for about 2,000 years. Christians are not alone in finding this hard to live out, and we are not free to soften the texts to make the difficulty go away.

But the position is not just "the Bible says so." It is built on a picture of what a human being is and what marriage is for. The Bible opens with a male and female made in God's image, joined as one flesh (Gen 2:24). Jesus reaffirms that pattern (Matt 19:4-6). The whole moral frame around sex assumes this design, and the prohibitions follow from it.

There is real disagreement here, and we should be honest about it. Many sincere readers, including Christian readers, argue that the biblical texts have been mistranslated, that they target abusive practices like temple prostitution, or that they do not address loving committed partnerships. Those readings are taken seriously below.

A note on what the Christian position does and does not say. It does not say that being attracted to the same sex is itself an act of sin. It does not single out same-sex sin as worse than other sins. It does say that the call to chastity, either celibacy or male-female marriage, applies to every Christian. That call is costly. The church should be honest about the cost and walk it with people, not at them.

Search-landing page for the "is homosexuality a sin" / "what does the Bible say about gay sex" question. The historic-orthodox Christian position is that same-sex sexual acts are sinful, while same-sex sexual orientation or temptation, per se, is not equivalent to a sinful act (though classical Christian anthropology treats disordered desire as part of fallen Concupiscence). The biblical witness on this is consistent across both Testaments and across the catholic tradition (Catholic, Orthodox, historic Protestant) for ~2,000 years. Modern affirming readings argue these texts are mistranslated, culturally bound, or address only abusive forms, these are addressed below.

Christian Position

Distinguish three things: orientation (pattern of attraction), desire (a given temptation), and act (chosen behavior). The biblical and historic consensus is that homosexual acts are sin; the moral weight of orientation/desire is debated within orthodoxy (Augustinian-Reformed framing treats disordered desire as itself disordered; some Protestant frames treat only consented acts as culpable).
Marriage is defined male-female (Gen 2:24; Matt 19:4-6), see Marriage. Any sexual activity outside that covenant is outside the biblical norm, including same-sex relations.
Same-sex sin is enumerated alongside other sins (greed, idolatry, drunkenness, slander), not singled out as uniquely heinous (1 Cor 6:9-11). The pastoral posture is: all are called to repentance; all may be "washed, sanctified, justified" (1 Cor 6:11).
Christians with same-sex attraction are full members of the church; the call is to chastity (either celibacy or male-female marriage), the same call given to all unmarried Christians.

Common Objection

The standard affirming reading argues: (1) the OT Levitical prohibitions are ritual-purity laws no longer binding; (2) Rom 1 condemns idolatrous pederasty or "unnatural" abandonment of one's own orientation, not committed same-sex relationships; (3) the words malakoi and arsenokoitai (1 Cor 6:9; 1 Tim 1:10) refer to temple prostitution or pederasty, not modern same-sex partnerships; (4) Jesus says nothing about same-sex relations; (5) the Sodom story is about gang-rape and inhospitality, not consensual same-sex love (Ezek 16:49 cites pride and neglect of the poor, not sexual orientation). On this reading, faithful, monogamous same-sex relationships are nowhere condemned.

Response

On Levitical purity: Lev 18-20 sits within a moral-ethical section (incest, adultery, child sacrifice, bestiality) that NT writers continue to treat as morally binding, not as Israel-specific ritual purity (1 Cor 5:1 invokes the Lev 18 incest prohibition as still binding on Christians).
On Rom 1:26-27: Paul's language, "natural" / "against nature" (kata physin / para physin), is creation-order language, not orientation-relative. The argument runs from the design of male-female to the deviation, not from individual psychology.
On arsenokoitai: the term is a Pauline neologism built directly from the LXX of Leviticus 18.21 / Lev 20:13 (arsenos koiten), explicitly drawing the OT prohibition forward into NT moral teaching. It is not narrowly "pederasty"; pederasty had specific Greek vocabulary (paiderastia) Paul declines to use.
On Jesus' silence: Jesus reaffirms male-female marriage (Matt 19:4-6) as the creation pattern, and condemns porneia, a broad first-century Jewish term that included all sex outside male-female marriage. No first-century Jewish teacher needed to specify "and also same-sex" because the prohibition was assumed.
On Sodom: the Sodom story is principally about violent injustice and hospitality breach, granted, see Sodom and Gomorrah Objection. The codex does not lean heavily on Genesis 19 for the moral case; the load-bearing texts are Lev 18-20, Rom 1, 1 Cor 6, and 1 Tim 1.
The historic-consensus weight matters: every branch of pre-modern Christianity (Catholic, Orthodox, Protestant), every patristic and medieval source, and the rabbinic Jewish tradition all read these texts as prohibiting same-sex acts. Affirming readings emerge in the late 20th century. The hermeneutical burden of proof is on the novel reading.

Common questions this page answers

Q: What does the Bible say about homosexuality?

Same-sex sexual acts are consistently named as outside God's creational design across both testaments (Gen 2:24, Lev 18:22, Rom 1:26-27, 1 Cor 6:9-11, 1 Tim 1:10); the homosexual orientation is not the sin in itself, but the acts are; Christian ethics couples this with full pastoral love for same-sex-attracted persons and the call to chastity that applies (in different forms) to all believers.
