Jerome on the 'Thou Shalt Not Lust, Thou Shalt Not Be Angry' Commandments

Jerome: And how is the Gospel lighter than the Law, seeing in the Law murder and adultery, but under the Gospel anger and lust also, are punished? Because by the Law many things are commanded which the Apostle fully teaches as cannot be fulfilled; by the Law works are required, by the Gospel the will is sought for, which even if it goes not into act, yet does not lose its reward. The Gospel commands what we can do, as that we lust not; this is in our own power; the Law punishes not the will but the act, as adultery. Suppose a virgin to have been violated in time of persecution; as here was not the will she is held as a virgin under the Gospel; under the Law she is cast out as defiled. [Catena Aurea 430]
