sinned are unjustly condemned; therefore they confess that those souls are evil that sin.  But these, as reason teaches, do not sin.  Therefore the extraneous class of evil souls of the Manichæans, whatever it may be, is a non-entity. 18.  Let us now look at that good class of souls, which again they exalt to such a degree as to say that it is the very substance of God.  But how much better it is that each one should recognize his own rank and merit, nor be so puffed up with sacrilegious pride as to believe that as often as he experiences a change in himself it is the substance of that supreme good, which devout reason holds and teaches to be unchangeable!  For behold! since it is manifest that souls do not sin in not being such as they cannot be; it follows that these supposititious souls, whatever they may be, do not sin at all, and moreover that they are absolutely non- existent; it remains that since there are sins, they find none to whom to attribute them except the good class of souls and the substance of God.  But especially are they pressed by Christian authority; for never have they denied that forgiveness of sins is granted when any one has been converted to God; never have they said (as they have said of many other passages) that some corrupter has interpolated this into the divine Scriptures.  To whom then are sins at- tributed?  If to those evil souls of the alien class, these also can become good, can possess the kingdom of God with Christ.  Which denying, they [the Manichæans] have no other class except those souls which they maintain are of the substance of God.  It remains that they acknowledge that not only these latter also, but these alone sin.  But I make no conten- tion about their being alone in sinning; yet they sin.  But are they compelled to sin by being commingled with evil?  If so compelled that there was no power of resisting, they do not sin.  If it is in their power to resist, and they voluntarily consent, we are compelled to find out through their [the Manichæan] teaching, why so great good things in supreme evil, why this evil in supreme good, unless it be that neither is that which they bring into suspicion evil, nor is that which they pervert by superstition supreme good? 181 From the Definitions Given of Sin and Will, He Overthrows the Entire Heresy…
