Cyril of Alexandria : In this discourse the Lord shows that the law was necessary to make ready the way, and the ministry of the prophets to prepare men for faith in this marvellous act, that so when the resurrection really took place, those who were troubled at its greatness might remember what was said of old, and be induced to believe. He brings forward therefore Moses and the prophets, interpreting their hidden meaning, and making plain to the worthy what to the unworthy was obscure, so settling in them that ancient and hereditary faith taught them by the sacred books which they possessed. For nothing which comes from God is without its use, but all and several of them have their appointed place and service. In their due place servants were sent before to make ready for the presence of the Master, by bringing in beforehand prophecy as the necessary preparative for faith, that, like some royal treasure, what had been foretold might in due season be brought forward from the concealment of its former obscurity, being unveiled and made plain by the clearness of the interpretation. — Commentary on the Gospel of Luke, Sermon 152 John Chrysostom : "But these things which God before had showed," etc. It is remarkable, that both in the first and in the second discourse, speaking to the same effect, that is, in the former, "By the determinate counsel and foreknowledge of God;" and in this, "God before had showed that Christ should suffer;" in neither does he adduce any particular text in proof. The fact is, that each one of such passages is accompanied with many accusations, and with mention of the punishment in store for them; "I will deliver up," says one, "the wicked in requital for His grave, and the rich in return for His death." And again, "Those things," he says, "which God before had showed by the mouth of all His prophets, that Christ should suffer, He hath so fulfilled." It shows the greatness of that "counsel," in that all spoke of it, and not one only. It does not follow, because the event was through ignorance, that it took place irrespectively of God's ordinance. — Homily on Acts 9 John Chrysostom : See how great is the Wisdom of God, when it uses the wickedness of others to bring about that which must be. "He hath fulfilled," he says: that they may not imagine that anything at all is wanting; for whatsoever Christ must needs suffer, has been fulfilled. But do not think, that, because the Prophets said this, and because ye did it through ignorance, this sufficeth to your exculpation. However, he does not express himself thus, but in milder terms says, "Repent ye therefore." — Homily on Acts 9
