69. AUGUSTINE answered: In this question you are speaking just as though we were at present inquiring what constituted a true priest, not what constituted true baptism. For that a man should be a true priest, it is requisite that he should be clothed not with the sacrament alone, but with righteousness, as it is written, "Let thy priests be clothed with righteousness."[778] But if a man be a priest in virtue of the sacrament alone, as was the high priest Caiaphas, the persecutor of the one most true Priest, then even though he himself be not truthful, yet what he gives is true, if he gives not what is his own but what is God's; as it is said of Caiaphas himself, "This spake he not of himself: but being high priest that year, he prophesied."[779] And yet, to use the same simile which you employed yourself: if you were to hear even from any one that was profane the prayer of the priest couched in the words suitable to the mysteries of the gospel, can you possibly say to him, Your prayer is not true, though he himself may be not only no true priest, but not a priest at all? seeing that the Apostle Paul said that certain testimony of I know not what Cretan prophet was true, though he was not reckoned among the prophets of God; for he says, "One of themselves, even a prophet of their own, said the Cretians are always liars, evil beasts, slow bellies: this witness is true."[780] If, therefore, the apostle even himself bore witness to the testimony of some obscure prophet of a foreign race, because he found it to be true, why do not we, when we find in any one what belongs to Christ, and is true even though the man with whom it may be found be deceitful and perverse, why do not we in such a case make a distinction between the fault which is found in the man, and the truth which he has not of his own but of God's? and why do we not say, This sacrament is true, as Paul said, "This witness is true?" Does it at all follow that we say, The man himself also is truthful, because we say, This sacrament is true? Just as I would ask whether the apostle counted that prophet among the prophets of the Lord, because he confirmed the truth of what he found to be true in him. Likewise the same apostle, when he was at Athens, perceived a certain altar among the altars of the false gods, on which was the inscription, "To the unknown God." And this testimony he made use of to build them up in Christ, to the extent of quoting the inscription in his sermon, and adding, "Whom, therefore, ye ignorantly worship, Him declare I unto you." Did he, because he found that altar either among the altars of idols, or set up by sacrilegious hands, therefore condemn or reject what he found in it that was true? or did he, because of the truth which he found upon it, therefore persuade them that they ought also to follow the sacrilegious practices of the pagans? Surely he did neither of the two; but presently, when, as he
