Pontifical Biblical Commission
The church points to several passages in the Bible as the basis for its teachings, including Genesis 19:1-11, Leviticus 18:22 and 20:13, I Corinthians 6:9, Romans 1:18-32, and I Timothy 1:10. In December 2019, the Pontifical Biblical Commission published a book that included an exegesis on these and other passages.
