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 has to be searched and invoked in the secret of a rational soul, which is called the interior man.
(De magistro 1)
The majesty of God surpasses by far our capacity for expression, because it is better to think of God than to talk of Him, and better is He still than what is thought.
(De Trinitate VII, 4,7)
