Homosexuality is sexual and romantic attraction to people of the same gender. This topic in sex ethics examines whether same-sex relationships and sexual acts are morally permissible. Traditional Religious Views condemn homosexuality: the Bible explicitly forbids homosexual acts (Leviticus 18:22, Romans 1:26-27); Natural Law says sex has the purpose of procreation, which is impossible in same-sex relations, making them 'contrary to nature'; the Roman Catholic Church calls homosexuality 'intrinsically disordered' and urges gay people to remain celibate. Secular and Progressive Views support homosexuality: Kantian Ethics argues same-sex relationships can express mutual respect, consent, and commitment; Utilitarianism holds that homosexuality maximizes happiness and reduces suffering; Modern Christian Views emphasize that God loves all people made in His image and justice demands acceptance.

New Testament:
Traditional Christian Interpretation:
The traditional Christian reading is that homosexual acts are explicitly and unambiguously forbidden by Scripture.
The Telos (Purpose) of Sex:
Sex has two purposes:
The Problem with Homosexuality:
Aquinas's View:
All sex outside marriage is wrong; homosexual sex doubly so because it can never be procreative. Even if two people of the same sex loved each other, sex between them would still be immoral because it violates the procreative purpose.
The Counter-Argument:
Critics note that if love and mutual support are placed at the center of marriage (not just procreation), then same-sex couples meet this standard. Additionally, sterile heterosexual couples can marry and have sex without procreating—why not same-sex couples?
Augustine's Teaching:
The Argument:
Scholar's View (John Boswell):
Progressive Christian Conclusion:
The spirit of Scripture is justice and compassion for the marginalized. Excluding gay people from marriage violates this spirit.
The Argument:
The Argument:
The Core Principle:
Sexual relationships must involve mutual consent, respect, and commitment, avoiding objectification and treating partners as ends in themselves.
Applied to Homosexuality:
Concern:
Sex driven purely by lust or personal gain (same-sex or opposite-sex) is problematic because it objectifies the other person. But committed same-sex partnerships express genuine respect and commitment.
The Core Principle:
Actions are moral if they maximize happiness and reduce suffering.
Applied to Homosexuality:
Additional Benefits:
Concerns:
Some argue that same-sex marriage 'alters the meaning of marriage' in society, potentially causing harm. But utilitarians counter: the benefits to gay couples far outweigh any abstract concerns about 'traditional marriage'.
Doctrine:
Pastoral Care:
The Church says it will treat gay people with 'respect, compassion, and sensitivity'. But this compassion does not extend to blessing same-sex unions or affirming homosexual practice.
1. Is the Bible's Teaching Clear?
2. Does Natural Law Condemn Homosexuality?
3. Is Sexual Orientation a Choice?
4. Can Same-Sex Marriage Be Consistent with Religious Belief?
"The Bible explicitly condemns homosexual acts in multiple places—Leviticus 18:22, Romans 1:26-27, and 1 Corinthians 6:9. Moreover, Natural Law teaches that sex has the purpose of procreation, which is impossible in same-sex relations. Homosexual acts therefore violate both Scripture and the natural order of creation. While Christians must treat gay people with compassion, they cannot affirm homosexual practice as morally acceptable."

Context: This represents the conservative religious position grounded in biblical interpretation and Natural Law theory.
"Sexual ethics must be judged by principles of consent, mutual respect, and the promotion of human flourishing—not by arbitrary rules based on outdated interpretations of Scripture. Same-sex relationships between consenting adults express love, commitment, and mutual respect. To deny gay people the right to marry is to deny them dignity and happiness, violating both Kantian and utilitarian ethical principles. Justice and compassion demand acceptance."

Context: This represents the modern, inclusive approach grounded in respect for persons and maximization of happiness.
Homosexuality forbidden by Bible and Natural Law; sex's purpose is procreation; same-sex acts are 'contrary to nature'.
Same-sex relationships permissible if consensual and respectful; gender irrelevant to moral evaluation of relationships.
Homosexuality permissible because it maximizes happiness and reduces suffering; restricting it causes harm.
All people have dignity; justice demands acceptance; Bible must be read historically; Jesus's message is love and justice for all.
Is ethics determined by divine command and natural purpose, or by consent, respect, and consequences?
Most secular societies and progressive churches now accept same-sex relationships; traditional religions continue to oppose them based on Scripture and Natural Law.
