"Upon my back have sinners built; they have done their iniquity afar off" [Psalm 129:3]. Why have they fought against me? Because "they could not prevail upon me." What is this? They could not build upon me. I consented not with them unto sin. For every wicked man persecutes the good on this account, because the good man consents not with him to evil. Suppose he do some evil, and the Bishop censure him not, the Bishop is a good man: suppose the Bishop censure him, the Bishop is a bad man. Suppose he carry off anything, let the man robbed be silent, he is a good man: let him only speak and rebuke, even though he does not reclaim his goods, he is everything bad. He is bad then who blames the robber, and he is good who robs!...Heed not that such an one speaks to you: it is a wicked man through whom It speaks to you; but the word of God, that speaks to you, is not wicked. Accuse God: accuse Him, if you can.
“They have often attacked me from my youth, but as a matter of fact they did not prevail against me.” And in the earlier, fifth psalm of ascent there is a similar beginning. This figure of speech is called “anaphora,” that is, a repetition of the same word at the beginning of a number of verses. Now we must understand the advanced age of the church when the apostle says, “Little children, it is the very last hour.” For whatever transpires at the end of the world proclaims its old age most aptly. Therefore, the church says that she has been well attacked from her youth so that you may understand that what has always been attacked has never come to an end. For she grows by the persecutions of the wicked and she grows larger by her own contrition. For even if she seems to lose holy men in this life, nonetheless she is shown to acquire them for a future homeland; and thus she cannot be brought to an end when it is agreed that she grows by her losses. Also the following words declare this to be the case; he says, “But as a matter of fact they did not prevail against me.” He says that the ones whom he had mentioned earlier as having fought against him were not able to overcome him. An attack is not completed, if further conflict breaks out. Nor should it be called a victory when it is certain that a renewed battle may take place.
[AD 430] Augustine of Hippo on Psalms 129:3
