among whom the Lord yet knoweth them that are His, which hear only the voice of the Shepherd, even when He calls by the voice of men like the Pharisees, of whom it was said, "Whatsoever they bid you observe, that observe and do."[392] 2. For as the spiritual man, keeping "the end of the commandment," that is, "charity out of a pure heart, and of a good conscience, and of faith unfeigned,"[393] can see some things less clearly out of a body which is yet "corruptible and presseth down the soul,"[394] and is liable to be otherwise minded in some things which God will reveal[395] to him in His own good time if he abide in the same charity, so in a carnal and perverse man something good and useful may be found, which has its origin not in the man himself, but in some other source. For as in the fruitful branch there is found something which must be purged that it may bring forth more fruit, so also a grape is often found to hang on a cane that is barren and dry or fettered. And so, as it is foolish to love the portions which require purging in the fruitful branch, whilst he acts wisely who does not reject the sweet fruit wherever it may hang, so, if any one cuts himself off from unity by rebaptizing, simply because it seemed to Cyprian that one ought to baptize again those who came from the heretics, such a man turns aside from what merits praise in that great man, and follows what requires correction, and does not even attain to the very thing he follows after. For Cyprian, while grievously abhorring, in his zeal for God, all those who severed themselves from unity, thought that thereby they were separated from baptism itself; while these men, thinking it at most a slight offence that they themselves are severed from the unity of Christ, even maintain that His baptism is not in that unity, but issued forth with them. Therefore they are so far from the fruitfulness of Cyprian, as not even to be equal to the parts in him which needed purging. * * * * *
