Don't you believe that there is in man a deep so profound as to be hidden even to him in whom it is?
Saint AugustineIt is He who gave to this intellectual nature free-will of such a kind, that if he wishes to forsake God his blessedness, misery should forthwith result.
Saint AugustineIf they find a Christian mistaken in a field which they themselves know well and hear him maintaining his foolish opinions about our books, how are they going to believe those books in matters concerning the resurrection of the dead, the hope of eternal life, and the kingdom of heaven.
Saint AugustineWhat you see is the bread and the chalice; that is what your own eyes report to you. But what your faith obliges you to accept is that the bread is the body of Christ and the chalice is the blood of Christ. This has been said very briefly, which may perhaps be sufficient for faith; yet faith does not desire instruction
Saint Augustine
