St. Ambrose
It is not the ambassador, it is not the messenger, but the Lord Himself that saveth His people. The Lord remaineth alone, for no man can be partner with God in forgiving sins; this office belongs solely to Christ, who taketh away the sins of the world.
Neither angel, nor archangel, nor yet even the Lord Himself (who alone can say “I am with you”), can, when we have sinned, release us, unless we bring repentance with us.
Prayer is the wing wherewith the soul flies to heaven, and meditation the eye wherewith we see God.
True repentance is to cease from sin.
