No one knows what he himself is made of, except his own spirit within him, yet there is still some part of him which remains hidden even from his own spirit; but you, Lord, know everything about a human being because you have made him...Let me, then, confess what I know about myself, and confess too what I do not know, because what I know of myself I know only because you shed light on me, and what I do not know I shall remain ignorant about until my darkness becomes like bright noon before your face.
Saint AugustineRemember this. When people choose to withdraw far from a fire, the fire continues to give warmth, but they grow cold. When people choose to withdraw far from light, the light continues to be bright in itself but they are in darkness. This is also the case when people withdraw from God.
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.
