Ezechiel 18:3

After the ancient examples of the patriarchs, let us equally pass on to the ancient documents of the legal Scriptures, that we may treat in order of all our canon. And since there are some who sometimes assert that they have nothing to do with the law (which Christ has not dissolved, but fulfilled), sometimes catch at such parts of the law as they choose; plainly do we too assert that the law has deceased in this sense, that its burdens, according to the sentence of the apostles, which not even the fathers were able to sustain, have wholly ceased: such (parts), however, as relate to righteousness not only permanently remain reserved, but even amplified; in order, to be sure, that our righteousness may be able to redound above the righteousness of the scribes and of the Pharisees. If “righteousness” must, of course chastity must too. …

2. Now I think they must, in the first place, be required to show, if they can, agreeably to their own definition, that the Creator is just in punishing according to their deserts, either those who perished at the time of the deluge, or the inhabitants of Sodom, or those who had quitted Egypt, seeing we sometimes behold committed crimes more wicked and detestable than those for which the above-mentioned persons were destroyed, while we do not yet see every sinner paying the penalty of his misdeeds. …

Such is our doctrine of punishment; and the inculcation of this doctrine turns many from their sins. But let us see, on the other hand, what is the response given on this subject by the priest of Jupiter or Apollo of whom Celsus speaks. It is this: “The mills of the gods grind slowly.” Another describes punishment as reaching “to children’s children, and to those who came after them.” How much better are those words of Scripture: “The fathers shall not be put to death for the children, nor the children for the fathers. …

This He saith not as acquitting them of sins, for He saith not simply, “Neither hath this man sinned, nor his parents,” but addeth, “that he should have been born blind, but that the Son of God should be glorified in him.” “For both this man hath sinned and his parents, but his blindness proceedeth not from that.” And this He said, not signifying that though this man indeed was not in such case, yet that others had been made blind from such a cause, the sins of their parents, since it cannot be that when one sinneth another should be punished. For if we allow this, we must also allow that he sinned before his birth. As therefore when He declared, “neither hath this man sinned,” He said not that it is possible to sin from one’s very birth, and be punished for it; so when He said, “nor his parents,” He said not that one may be punished for his parents’ sake. …

7. Be quiet, O thou that dost exalt thyself; vaunt not thyself! For if thy wealth has lifted up thy heart, it is not more abundant than that of Hezekiah, who went in and boasted of it before the Babylonians, (yet) it was all of it carried away and went to Babylon. And if thou gloriest in thy children, they shall be led away from thee to the Beast, as the children of King Hezekiah were led away, and became eunuchs in the palace of the King of Babylon. …
