ACC ~ 2 Timothy 3 v14

MIND AND MOUTH AT ONE. JEROME: Read the divine Scriptures constantly. Never, indeed, let the sacred volume be out of your hand. Learn what you have to teach. … Do not let your deeds belie your words, lest when you speak in church someone may mentally reply, “Why do you not practice what you preach?” He is a fine and dainty master who, with his stomach full, reads us a homily on fasting. Let the robber accuse others of covetousness if he will. The mind and mouth of a priest of Christ should be at one. LETTERS 52.7.

WHETHER GOD MAKES MEDICINES EFFECTIVE. AUGUSTINE: It may happen that even with the assistance of holy men, or even if the holy angels themselves take part, no one rightly learns those things which pertain to life with God unless he is made by God docile to God. … Medicines for the body which are administered to men by men do not help unless health is conferred by God, who can cure them without medicines. Yet they are nevertheless applied even though they are useless without his aid. And if they are applied courteously, they are considered to be among works of mercy or kindness. In the same way, the benefits of teaching profit the mind when they are applied by men where assistance is granted by God, who could have given the gospel to man even though it came not from men nor through a man. ON CHRISTIAN DOCTRINE 4.16.33.
