Homosexuality is a sin in the Bible  Homosexuality is "a grievous sin" in the Bible (Gen 18:20), a capital crime (Lev 20:13), and punishable by exclusion from the Kingdom of Heaven (1 Cor 6:9-10). Christians - especially priests - must accept the Bible as the ultimate authority. Christian ministry is therefore incompatible with homosexuality. Jesus was a radical teacher and overturned Jewish tradition where He saw it was necessary to do so; His silence on homosexuality indicates that He saw no need in this case.
