Question & Answer 109

Q: Does God, in this commandment, forbid only such scandalous sins as adultery?

A: We are temples of the Holy Spirit, body and soul,
and God wants both to be kept clean and holy.
That is why he forbids
everything which incites unchastity,1
whether it be actions, looks, talk, thoughts, or desires.2
