biblical passages
There are six verses in all:
Leviticus
Romans 1:26-27 is a strong condemnation of moral degeneracy in society, as part of Paul's argument that all have sinned and fall short of the glory of God. Paul's warning of sexual abuse as the marks of moral decline remain just as real and as forceful as in the past. But Paul wasn't condemning committed adult gay relationships because on the whole they were hidden in his day. His vocabulary indicates that he sees homosexual sin as the product of a sick heterosexual world. There are plenty of issues within the gay world that a Christian must challenge, but perhaps not the issues of sexuality itself, which they don't really understand.
1 Corinthians 6:9-10 has two phrases among its list of evil behaviour which marked the Corinthians before they were converted. The malakoi (‘the soft ones') is sometimes translated male prostitutes and the arsenokoitoi, the sodomites, may well be a reference back to the Leviticus evils, but no-one knows for sure since it is not used beyond the New Testament.
1 Timothy
Romans 1 is seen as targeting those who abandon ‘natural relations.'
