Man was not created as an irrational animal bent toward the earth but, erect in stature, a reminder to look above.
(De Civ. Dei XXII, 24, 4)
To have a good idea of God is the truest beginning of piety.
(De libero arbitrio I, 2,5)
If you are the Body of Christ and its members, it is your mystery that is placed on the Lord's table. It is your mystery that you receive. To what you are, you respond «Amen», and by responding, you become part of it.
