The First Apology
Chapter 41. The crucifixion predicted
And again, in another prophecy, the Spirit of prophecy, through the same David, intimated that Christ, after He had been crucified, should reign, and spoke as follows: “Sing to the Lord, all the earth, and day by day declare His salvation. For great is the Lord, and greatly to be praised, to be feared above all the gods. For all the gods of the nations are idols of devils; but God made the heavens. Glory and praise are before His face, strength and glorying are in the habitation of His holiness. Give Glory to the Lord, the Father everlasting. Receive grace, and enter His presence, and worship in His holy courts. Let all the earth fear before His face; let it be established, and not shaken. Let them rejoice among the nations. The Lord hath reigned from the tree.”
Chapter 42. Prophecy using the past tense
But when the Spirit of prophecy speaks of things that are about to come to pass as if they had already taken place, —as may be observed even in the passages already cited by me, —that this circumstance may afford no excuse to readers [for misinterpreting them], we will make even this also quite plain. The things which He absolutely knows will take place, He predicts as if already they had taken place. And that the utterances must be thus received, you will perceive, if you give your attention to them. The words cited above, David uttered 1500 years before Christ became a man and was crucified; and no one of those who lived before Him, nor yet of His contemporaries, afforded joy to the Gentiles by being crucified.
But our Jesus Christ, being crucified and dead, rose again, and having ascended to heaven, reigned; and by those things which were published in His name among all nations by the apostles, there is joy afforded to those who expect the immortality promised by Him.
Chapter 43. Responsibility asserted
But lest some suppose, from what has been said by us, that we say that whatever happens, happens by a fatal necessity, because it is foretold as known beforehand, this too we explain. We have learned from the prophets, and we hold it to be true, that punishments, and chastisements, and good rewards, are rendered according to the merit of each man’s actions. Since if it be not so, but all things happen by fate, neither is anything at all in our own power. For if it be fated that this man, e.g., be good, and this other evil, neither is the former meritorious nor the latter to be blamed. And again, unless the human race have the power of avoiding evil and choosing good by free choice, they are not accountable for their actions, of whatever kind they be. But that it is by free choice they both walk uprightly and stumble, we thus demonstrate. We see the same man making a transition to opposite things. Now, if it had been fated that he were to be either good or bad, he could never have been capable of both the opposites, nor of so many transitions. But not even would some be good and others bad, since we thus make fate the cause of evil, and exhibit her as acting in opposition to herself; or that which has been already stated would seem to be true, that neither virtue nor vice is anything, but that things are only reckoned good or evil by opinion; which, as the true word shows, is the greatest impiety and wickedness. But this we assert is inevitable fate, that they who choose the good have worthy rewards, and they who choose the opposite have their merited awards. For not like other things, as trees and quadrupeds, which cannot act by choice, did God make man: for neither would he be worthy of reward or praise did he not of himself choose the good, but were created for this end; nor, if he were evil, would he be worthy of punishment, not being evil of himself, but being able to be nothing else than what he was made.
