14 After considering these instances of the fulfillment of prophecy about kings and people acting as persecutors, and then becoming believers, about the destruction of idols, about the blindness of the Jews, about their testimony to the writings which they have preserved, about the folly of heretics, about the dignity of the Church of true and genuine Christians, the inquirer would most reasonably receive the testimony of these prophets about the divinity of Christ. No doubt, if we were to begin by urging him to believe prophecies yet unfulfilled, he might justly answer, What have I to do with these prophets, of whose truth I have no evidence? But, in view of the manifest accomplishment of so many remarkable predictions, no candid person would despise either the things which were thought worthy of being predicted in those early times with so much solemnity, or those who made the predictions. To none can we trust more safely, as regards either events long past or those still future, than to men whose words are supported by the evidence of so many notable predictions having been fulfilled.
