78. ‘We Christians therefore hold the mystery not in the wisdom of Greek arguments, but in the power of faith richly supplied to us by God through Jesus Christ. And to show that this statement is true, behold now, without having learned letters, we believe in God, knowing through His works His providence over all things. And to show that our faith is effective, so now we are supported by faith in Christ, but you by professional logomachies. The portents of the idols among you are being done away, but our faith is extending everywhere. You by your arguments and quibbles have converted none from Christianity to Paganism. We, teaching the faith on Christ, expose your superstition, since all recognise that Christ is God and the Son of God. You by your eloquence do not hinder the teaching of Christ. But we by the mention of Christ crucified put all demons to flight, whom you fear as if they were gods. Where the sign of the Cross is, magic is weak and witchcraft has no strength.
