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.
The absence of the Lord is not an absence. Just believe, and the one who you do not see is with you.
From infancy to old age, each age in all men has its own special beauty.
(De div. quaest. LXXXIII q.44)
