15. But some one may say that the tares within may more easily be converted into wheat. I grant that it is so; but what has this to do with the question of repeating baptism? You surely do not maintain that if a man converted from heresy, through the occasion and opportunity given by his conversion, should bear fruit before another who, being within the Church, is more slow to be washed from his iniquity, and so corrected and changed, the former therefore needs not to be baptized again, but the churchman to be baptized again, who was outstripped by him who came from the heretics, because of the greater slowness of his amendment. It has nothing, therefore, to do with the question now at issue who is later or slower in being converted from his especial waywardness to the straight path of faith, or hope, or charity. For although the bad within the fold are more easily made good yet it will sometimes happen that certain of the number of those outside will outstrip in their conversion certain of those within; and while these remain in barrenness, the former, being restored to unity and communion, will bear fruit with patience, thirty-fold, or sixty-fold, or a hundred-fold. Or if those only are to be called tares who remain in perverse error to the end, there are many ears of corn outside, and many tares within.
16. But it will be urged that the bad outside are worse than those within. It is indeed a weighty question, whether Nicolaus, being already severed from the Church, or Simon, who was still within it, was the worse,—the one being a heretic, the other a sorcerer. But if the mere fact of division, as being the clearest token of violated charity, is held to be the worse evil, I grant that it is so. Yet many, though they have lost all feelings of charity, yet do not secede from considerations of worldly profit; and as they seek their own, not the things which are Jesus Christ’s, what they are unwilling to secede from is not the unity of Christ, but their own temporal advantage. Whence it is said in praise of charity, that she "seeketh not her own."
