Isaias 8:20

9. For as God is His own eternal happiness, and is besides the bestower of happiness, so He is His own eternal light, and is also the bestower of light. He envies the good of none, for He is Himself the source of happiness to all good beings; He fears the evil of none, for the loss of all evil beings is in their being abandoned by Him. He can neither be benefited by those on whom He Himself bestows happiness, nor is He afraid of those whose misery is the doom awarded by His own judgment. Very different, O Manichæus, is the object of your worship. You have departed from God in the pursuit of your own fancies, which of all kinds have increased and multiplied in your foolish roving hearts, drinking in through the sense of sight the light of the heavenly bodies. …

First of all, then, I offer to the Lord my God, who is also my defence and guide, unspeakable thanks, because I was not misled in my views respecting our holy brethren and fellow-bishops who sat as judges in that case. His answers, indeed, they not without reason approved; because they had not to consider how he had in his writings stated the points which were objected against him, but what he had to say about them in his reply at the pending examination. A case of unsoundness in the faith is one thing, one of incautious statement is another thing. Now sundry objections were urged against Pelagius out of a written complaint, which our holy brethren and fellow-bishops in Gaul, Heros and Lazarus, presented, being themselves unable to be present, owing (as we afterwards learned from credible information) to the severe indisposition of one of them. …

What the middle wall of partition is, he interprets by saying, “the enmity having abolished in His flesh, even the law of commandments contained in ordinances.” Some indeed affirm that he means the wall of the Jews against the Greeks, because it did not allow the Jews to hold intercourse with the Greeks. To me, however, this does not seem to be the meaning, but rather that he calls “the enmity in the flesh,” a middle wall, in that it is a common barrier, cutting us off alike from God. As the Prophet says, “Your iniquities separate between you and Me;” ( Isa. lix. 2 .) for that enmity which He had both against Jews and Gentiles was, as it were, a middle wall. And this, whilst the law existed, was not only not abolished, but rather was strengthened; “for the law,” saith the Apostle, “worketh wrath.” ( Rom. iv. …

5. The better to deceive men they have added to the maxim given above the saving clause “but not without the grace of God;” and this may at the first blush take in some readers. However, when it is carefully sifted and considered, it can deceive nobody. For while they acknowledge the grace of God, they tell us that our acts do not depend upon His help. Rather, they understand by the grace of God free will and the commandments of the Law. They quote Isaiah’s words: “God hath given the law to aid men,” and say that we ought to thank Him for having created us such that of our own free will we can choose the good and avoid the evil. Nor do they see that in alleging this the devil uses their lips to hiss out an intolerable blasphemy. …

Serenus : God at man’s creation implanted in him naturally complete knowledge of the law, and if this had been kept by man, as at the beginning, according to the Lord’s purposes, there would not have been any need for another law to be given, which He afterwards proclaimed in writing: for it were superfluous for an external remedy to be offered, where an internal one was still implanted and vigorous. But since this had been, as we have said, utterly corrupted by freedom and the opportunity of sinning, the severe restrictions of the law of Moses were added as the executor and vindicator of this (earlier law) and to use the expressions of Scripture, as its helper, that through fear of immediate punishment men might be kept from altogether losing the good of natural knowledge, according to the word of the prophet who says “He gave the law to help them:” and it is also described by the Apost …
