Book II.
He undertakes to examine the second letter of the Pelagians, filled, like the first, with calumnies against the Catholics--a letter that was sent by them to Thessalonica in the name of eighteen bishops; and, first of all, he shows, by the comparison of the heretical writings with one another, that the Catholics are by no means falling into the errors of the Manicheans in detesting the dogmas of the Pelagians. He repels the calumny of prevarication incurred by the Roman clergy in the latter condemnation of Pelagius and Coelestius by Zosimus, showing that the Pelagian dogmas were never approved at Rome, although for some time, by the clemency of Zosimus, Coelestius was mercifully dealt with, with a view to leading him to the correction of his errors. He shows that, under the name of grace, Catholics neither assert a doctrine of fate, nor attribute respect of persons to God; although they truly say that God's grace is not given according to human merits, and that the first desire of good is inspired by God; so that a man does not at all make a beginning of a change from bad to good, unless the unbought and gratuitous mercy of God effects that beginning in him.
Chapter 1.--Introduction; The Pelagians Impeach Catholics as Manicheans.
Let me now consider a second letter, not of Julian's alone, but common to him with several bishops, which they sent to Thessalonica; and let me answer it, with God's help, as I best can. And lest this work of mine become longer than the necessity of the subject itself requires, what need is there to refute those things which do not contain the insidious poison of their doctrine, but seem only to plead for the acquiescence of the Eastern bishops for their assistance, or, on behalf of the catholic faith, against the profanity, as they say, of the Manicheans; with no other view except, a horrible heresy being presented to them, whose adversaries they profess themselves to be, to lie hid as the enemies of grace in praise of nature? For who at any time has stirred any question of these matters against them? or what catholic is displeased because they condemn those whom the apostle foretold as departing from the faith, having their conscience seared, forbidding to marry, abstaining from meats that they think unclean, not thinking that all things were created by God? [2622] Who at any time constrained them to deny that every creature of God is good, and there is no substance which the supreme God has not made, except God Himself, who was not made by any? It is not such things as these, which it is plain are catholic truths, that are rebuked and condemned in them; because not alone the catholic faith holds in detestation the Manichean impiety as exceedingly foolish and mischievous, but also all heretics who are not Manicheans. Whence even these Pelagians do well to utter an anathema against the Manicheans, and to speak against their errors. But they do two evil things, for which they themselves must also be anathematized--one, that they impeach catholics under the name of Manicheans, the other, that they themselves also are introducing the heresy of a new error. For they are not therefore sound in the faith because they are not labouring under the disease of the Manicheans. The kind of pestilence is not always one and the same--as in the bodies, so also in the minds. As, therefore, the physician of the body would not have pronounced a man free from peril of death whom he might have declared free from dropsy, if he had seen him to be sick of some other mortal disease; so truth is not acknowledged in their case because they are not Manicheans, if they are raving in some other kind of perversity. Wherefore what we anathematize with them is one thing, what we anathematize in them is another. For we hold in abhorrence with them what is rightly offensive to them also; just as, nevertheless, we hold in abhorrence in them that for which they themselves are rightly offensive.

Chapter 2 [II.]--The Heresies of the Manicheans and Pelagians are Mutually Opposed, and are Alike Reprobated by the Catholic Church.
The Manicheans say that the good God is not the Creator of all natures; the Pelagians that God is not the Purifier, the Saviour, the Deliverer of all ages among men. The catholic Church condemns both; as well maintaining God's creation against the Manicheans, that no nature may be denied to be framed by Him, as maintaining against the Pelagians that in all ages human nature must be sought after as ruined. The Manicheans rebuke the concupiscence of the flesh, not as if it were an accidental vice, but as if it were a nature bad from eternity; the Pelagians approve it as if it were no vice, but even a natural good. The catholic faith condemns both, saying to the Manicheans, "It is not nature, but it is vice;" saying to the Pelagians, "It is not of the Father, but it is of the world;" in order that both may allow it as an evil sickness to be cured--the former by ceasing to believe it, as it were, incurable, the latter by ceasing to proclaim it as laudable. The Manicheans deny that to a good man the beginning of evil came from free will; the Pelagians say that even a bad man has free will sufficiently to perform the good commandment. The catholic Church condemns both, saying to the former, "God made man upright," [2623] and saying to the latter, "If the Son shall make you free, ye shall be free indeed." [2624] The Manicheans say that the soul, as a particle of God, has sin by the commixture of an evil nature; the Pelagians say that the soul is upright, not indeed a particle, but a creature of God, and has not even in this corruptible life any sin. The catholic Church condemns both, saying to the Manicheans, "Either make the tree good and its fruit good, or make the tree evil and its fruit evil," [2625] which would not be said to man who cannot make his own nature, unless because sin is not nature, but vice; and saying to the Pelagians, "If we say that we have no sin we deceive ourselves, and the truth is not in us." [2626] In these diseases, opposed as they are to one another, the Manicheans and the Pelagians are at issue, with dissimilar will but with similar vanity, separated by different opinions, but close together by a perverse mind.
