To have a good idea of God is the truest beginning of piety.
(De libero arbitrio I, 2,5)
Let us love the Lord our God, let us love the Church. He, like a father; she, like a mother. He, like a master; she, like a servant. For we are the children of this very servant.
God became a man so that by following a man, which you can do, you will reach God, which you could not do.
