The following table lists the specific sexual relationships that God, in His Holy Scriptures - the Bible - has either forbidden or allowed. In reading the table one needs to be aware that Jesus Christ ensured that all understood that intent was equal to actual participation in the relationship, hence lusting after a woman by a man constitutes adultery: “But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart” Matthew 5:28.
