If a man lies with a male as with a woman, both of them have committed an abomination; they shall surely be put to death.(Leviticus 20:13).
Most Christian churches hold the position that you should 'Love the sinner, but hate the sin'. This is generally interpreted to mean that Christians should show love and compassion to homosexuals, but that homosexuals should not engage in sexual activity. This is because most churches teach that sex should only happen within marriage, which the Church defines as being between a man and a woman.
The Roman Catholic Church states:
This inclination, which is objectively disordered, constitutes for most of them a trial. They must be accepted with respect, compassion and sensitivity. Every sign of unjust discrimination in their regard should be avoided...Homosexual people are called to chastity.Catechism of the Catholic Church 1992, paras 2358-9
The Quaker view on homosexuality is accepting:
Where there is a genuine tenderness, an openness to responsibility, and the seed of commitment, God is surely not shut out. Can we not say that God can enter any relationship in which there is a measure of selfless love? ...To reject people on the grounds of their sexual behaviour is a denial of God's creation.Towards a Quaker View of Sex, 1963
Most Christians will take a position somewhere between these two views. Some churches offer support to homosexuals in leading a chaste life, while others readily accept openly homosexual people in positions of authority. However, few Christian groups will give a definitive statement on the issue as it would cause divisions within the community.
