CHAP. XIV.--19. Nor is it material, when we are considering the question of the genuineness and holiness of the sacrament, "what the recipient of the sacrament believes, and with what, faith he is imbued." It is of the very highest consequence as regards the entrance into salvation, but is wholly immaterial as regards the question of the sacrament. For it is quite possible that a man may be possessed of the genuine sacrament and a corrupted faith, as it is possible that he may hold the words of the creed in their integrity, and yet entertain an erroneous belief about the Trinity, or the resurrection, or any other point. For it is no slight matter, even within the Catholic Church, to hold faith entirely consistent with the truth about even God Himself, to say nothing of any of His creatures. Is it then to be maintained, that if any one who has been baptized within the Catholic Church itself should afterwards, in the course of reading, or by listening to instruction, or by quiet argument, find out, through God's own revelation, that he had before believed otherwise than he ought, it is requisite that he should therefore be baptized afresh? But what carnal and natural man is there who does not stray through the vain conceits[134] of his own heart, and picture God's nature to himself to be such as he has imagined out of his carnal sense, and differ from the true conception of God as far as vanity from truth? Most truly, indeed, speaks the apostle, filled with the light of truth: "The natural man," says he, "receiveth not the things of the Spirit of God."[135] And yet herein he was speaking of men whom he himself shows to have been baptized. For he says to them, "Was Paul crucified for you? or were ye baptized in the name of Paul?"[136] These men had therefore the sacrament of baptism; and yet, inasmuch as their wisdom was of the flesh, what could they believe about God otherwise than according to the perception of their flesh, according to which "the natural man receiveth not the things of the Spirit of God?" To such he says: "I could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ. I have fed you with milk, and not with meat: for hitherto ye were not able to bear it, neither yet now are ye able. For ye are yet carnal."[137] For such are carried about with every wind of doctrine, of which kind he says, "That we be no more children, tossed to and fro, and carried about with every wind of doctrine."[138] Is it then true that, if these men shall have advanced even to the spiritual age of the inner man, and in the integrity of understanding shall have learned how far different from the requirements of the truth has been the belief which they have been led by the fallacious character of their conceits to entertain of God, they are therefore to be baptized again? For, on this principle, it would be possible for a Catholic catechumen to light upon the writings of some heretic, and,
