Justin Martyr on Free Will and Foreknowledge in 160CE

In the beginning, He made the human race with the power of thought and of choosing the truth and doing right, so that all men are without excuse before God. … Lest some suppose, from what has been said by us, that we say that whatever occurs 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, chastisements, and good rewards are rendered according to the merit of each man’s actions.

Now, if this is not so, but all things happen by fate, then neither is anything at all in our own power. For if it is predetermined that this man will be good, and this other man will be evil, neither is the first one meritorious nor the latter man to be blamed. And again, unless the human race has the power of avoiding evil and choosing good by free choice, they are not accountable for their actions. … Those who were foreknown to be unrighteous, whether men or angels, are not made wicked by God’s fault. Rather, each man is what he will appear to be through his own fault.
