Tertullian

For we now affirm: This is lawful to the Lord alone: may the power of His indulgence be operative at the present day! At those times, however, in which He lived on earth we lay this down definitively, that it is no prejudgment against us if pardon used to be conferred on sinners-even Jewish ones. For Christian discipline dates from the renewing of the Testament, and (as we have premised) from the redemption of flesh-that is, the Lord's passion.
