There are at least three passages that refer to non-heterosexual sexual intercourse in the New Testament (NT), all of which are found in the Pauline epistles: Romans 1:26–27, 1 Corinthians 6:9–10, and 1 Timothy 1:9–10. A fourth passage, found in Jude 1:7, is often interpreted as referring to homosexuality. In the synoptic Gospels, Jesus discusses marriage only in a heterosexual context when he cites the Book of Genesis during a discussion of marriage (Mark 10:6–9 and Matthew 19:4–6).
