is idolatry) and great uncleanness cannot prevent what he receives from being holy baptism, even though he be baptized with the same words of the gospel by another man covetous like himself. * * * * * CHAP. V.--7. "Further," Cyprian goes on to say, "in vain do some, who are overcome by reason, oppose to us custom, as though custom were superior to truth, or that were not to be followed in spiritual things which has been revealed by the Holy Spirit, as the better way."[198] This is clearly true, since reason and truth are to be preferred to custom. But when truth supports custom, nothing should be more strongly maintained. Then he proceeds as follows: "For one may pardon a man who merely errs, as the Apostle Paul says of himself, 'Who was before a blasphemer, a persecutor, and injurious; but I obtained mercy, because I did it ignorantly;'[199] but he who, after inspiration and revelation given, perseveres advisedly and knowingly in his former error, sins without hope of pardon on the ground of ignorance. For he rests on a kind of presumption and obstinacy, when he is overcome by reason." This is most true, that his sin is much more grievous who has sinned wittingly than his who has sinned through ignorance. And so in the case of the holy Cyprian, who was not only learned, but also patient of instruction, which he so fully himself understood to be a part of the praise of the bishop whom the apostle describes,[200] that he said, "This also should be approved in a bishop, that he not only teach with knowledge, but also learn with patience."[201] I do not doubt that if he had had the opportunity of discussing this question, which has been so long and so much disputed in the Church, with the pious and learned men to whom we owe it that subsequently that ancient custom was confirmed by the authority of a general Council, he would have shown, without hesitation, not only how learned he was in those things which he had grasped with all the security of truth, but also how ready he was to receive instruction in what he had failed to perceive. And yet, since it is so clear that it is much more grievous to sin wittingly than in ignorance, I should be glad if any one would tell me which is the worse,--the man who falls into heresy, not knowing how great a sin it is, or the man who refuses to abandon his covetousness, knowing its enormity. I might even put the question thus: If one man unwittingly fall into heresy, and another knowingly refuse to depart from idolatry, since the apostle himself says, "The covetous man, which is an idolater;" and Cyprian too understood the same passage in just the same way, when he says, in his letter to Antonianus, "Nor let the new heretics flatter themselves in this, that they say they do not communicate with idolaters, whereas there are amongst them both adulterers and covetous persons, who are held guilty of the sin of idolatry; 'for know this, and understand, that no
