In the Institutes, I, viii, 8, Calvin says, "Yet from what source but God shall we say have come those prophecies which Isaiah at the same time utters concerning release? He names Cyrus (Isa. 45:1) through whom the Chaldeans had to be conquered and the people set free. … No one could have divined then that there was to be a man named Cyrus who would wage war with the Babylonians, would subdue such a powerful monarchy, and terminate the exile of the people of Israel. Does not this bare narrative, without any verbal embellishment, plainly show the things Isaiah recounts to be undoubted oracles of God, not the conjectures of a man?" Of course, Calvin is absolutely correct. For this reason, the father of lies (John 8:44) found it necessary to raise up his false prophets, the critical scholars, to deny that Isaiah actually wrote the words!
