4.3.4   Those impostors then, whom they style Mathematicians, I consulted without scruple; because they seemed to use no sacrifice, nor to pray to any spirit for their divinations: which art, however, Christian and true piety consistently rejects and condemns. For, it is a good thing to confess unto Thee, and to say, Have mercy upon me, heal my soul, for I have sinned against Thee; and not to abuse Thy mercy for a licence to sin, but to remember the Lord's words, Behold, thou art made whole, sin no more, lest a worse thing come unto thee. All which wholesome advice they labour to destroy, saying, "The cause of thy sin is inevitably determined in heaven"; and "This did Venus, or Saturn, or Mars": that man, forsooth, flesh and blood, and proud corruption, might be blameless; while the Creator and Ordainer of heaven and the stars is to bear the blame. And who is He but our God? the very sweetness and well-spring of righteousness, who renderest to every man according to his works: and a broken and contrite heart wilt Thou not despise.
