Christian Attitudes to Same-Sex Relationships

Why Christians disagree

A same-sex relationship is a romantic or sexual relationship between people of the same sex. Christians disagree about whether such relationships should include sexual activity, whether churches should bless them, and whether same-sex couples should marry in church.

These are separate questions. A Christian may welcome gay and lesbian people and oppose discrimination while still believing that sex belongs only within marriage between a man and a woman. Other Christians believe that welcoming people fully should include recognising their loving, faithful partnerships.

The disagreement concerns how Christians understand biblical authority, God's purposes for sex and Jesus' teaching about love. It exists both between traditions and within them.

Biblical passages used to oppose same-sex sexual activity

Leviticus 18:22 prohibits a man having sexual relations with another man as with a woman. Leviticus 20:13 repeats this prohibition, describing the act as “detestable”, and prescribes death as its punishment within ancient Israel's law.

Christians who take a traditional view interpret these passages as expressing a continuing moral prohibition. They do not generally argue that Christians should enforce the ancient death penalty: accepting a moral teaching is distinct from applying an ancient legal punishment.

1 Timothy 1:8–10 begins by saying that “the law is good if one uses it properly”. It then identifies behaviour contrary to sound teaching. In the NIV-UK translation, the list includes “those practising homosexuality”, alongside other groups such as slave traders, liars and perjurers. Traditional interpreters understand this as New Testament confirmation that same-sex sexual acts are wrong. The passage concerns conduct; it does not explicitly discuss sexual orientation as understood today.

Traditional Christians also connect these passages with the creation accounts. Genesis 1:27 describes God creating humanity “male and female”, while Genesis 1:28 commands people to “Be fruitful and increase in number”. They understand male–female marriage and procreation as part of God's design for sexual relationships.

Different interpretations of the same passages

Christians who affirm same-sex relationships argue that biblical texts must be understood in their historical context. Leviticus contains laws governing ancient Israel's religious and social life. Christians do not apply every rule about food, clothing or punishment today, so these Christians question whether its sexual prohibitions should be transferred directly to modern relationships.

Some interpret the prohibitions as connected with ancient religious practices rather than as a judgement on every loving same-sex partnership. Traditional Christians reply that some laws express enduring moral principles even when other ancient regulations no longer apply. The disagreement is therefore about which teachings remain binding and why.

There is also disagreement over the Greek term translated as “those practising homosexuality” in 1 Timothy 1:10. Some Christians argue that it refers to exploitative practices, such as prostitution or sexual abuse, rather than equal, committed partnerships. Others understand it as a broader prohibition of male same-sex sexual activity. The narrower interpretation is an argument, not an agreed translation.

Affirming Christians also emphasise that everyone is made in God's image and deserves dignity. Jesus taught, “Love your neighbour as yourself” (Mark 12:31), and welcomed people who were excluded by others. They argue that love, faithfulness and responsibility should be the main tests of a relationship. Traditional Christians respond that loving a person does not necessarily mean approving every action: they believe compassion and obedience to sexual teachings can coexist.

Catholic teaching and disagreement among Catholics

Official Roman Catholic teaching distinguishes same-sex attraction from sexual acts. Attraction is not itself treated as a sin, but same-sex sexual activity is considered morally wrong. Gay and lesbian Catholics are called to chastity, which means abstaining from sexual activity outside the Church's understanding of marriage.

This teaching draws on Natural Law: sex should unite a married man and woman in love and remain open to procreation. Same-sex sexual acts cannot fulfil the procreative purpose in this understanding. The Church therefore does not recognise same-sex marriage.

The Catechism also says that gay and lesbian people must be treated with “respect, compassion and sensitivity” and that unjust discrimination should be avoided.

Not every Catholic agrees with the official position. New Ways Ministry, a Catholic advocacy organisation, argues for affirming interpretations of biblical passages and greater inclusion of gay and lesbian people. Its position illustrates disagreement among Catholics; it is not the official teaching of the Catholic Church.

Anglican, Protestant and Quaker approaches

The Church of England maintains a definition of marriage as a lifelong union between one man and one woman. Nevertheless, Anglicans disagree about same-sex relationships and how churches should recognise them. This shows why a church's formal teaching should not be assumed to describe every member's beliefs.

Other churches have reached different decisions. The Scottish Episcopal Church, which is also Anglican, voted in 2017 to allow same-sex marriages. The United Reformed Church also permits same-sex marriages in its churches. These examples show that Protestant and Anglican traditions do not share one position.

Quakers support same-sex marriage and emphasise the quality of a relationship rather than the partners' sex. Their statement Towards a Quaker View of Sex (1963) says that where there is “genuine tenderness”, responsibility and commitment, “God is surely not shut out”. For this approach, a faithful same-sex relationship can express Christian love.

These beliefs influence real church life: whether couples can marry in church, how they are welcomed and whether they are expected to remain celibate.

Reaching a justified judgement

The strength of the traditional argument is its appeal to specific biblical prohibitions and a consistent understanding of male–female marriage. Its challenge is explaining why these prohibitions remain binding while many other ancient laws do not.

The strength of the affirming argument is its attention to historical context, human dignity and the love shown within committed relationships. Its challenge is explaining why these principles justify a narrower reading of passages traditionally understood as prohibitions.

A justified conclusion should address that disagreement. For example, someone might support church recognition of same-sex partnerships because they consider faithful love and contextual interpretation more persuasive than applying ancient prohibitions universally. Alternatively, someone might uphold traditional teaching because they regard the biblical passages and Natural Law as binding, while insisting that this never justifies mistreatment or unjust discrimination.
