John 1:33

Now this it was in Him that John saw, and came to know which he did not know. Not that he did not know Him to be the Son of God, or that he did not know Him to be the Lord, or not know Him to be the Christ; or that he did not know this too, that it was He who should baptize with water and with the Holy Ghost. This he did know; but that he should do this so as to retain the authority to Himself and transfer it to none of His ministers, this is what he learnt in the dove. For by this authority, which Christ has retained to Himself alone, and conferred upon none of His ministers, though He has deigned to baptize by His ministers; by this authority, I say, stands the unity of the Church, which is figured in the dove, concerning which it is said, "My dove is one, the only one of her mother." For if, as I have already said, my brethren, the authority were transferred by the Lord to His minister, there would be as many baptisms as ministers, and the unity of baptism would no longer exist.

Mark, brethren; before our Lord Jesus Christ came to His baptism (for it was after the baptism that the dove descended, whereby John recognized something that was peculiar to Him, since he was told, "Upon whom thou shalt see the Spirit descending like a dove, and remaining on Him, the same is He that baptizeth with the Holy Ghost"), John knew that He it was that baptizeth with the Holy Ghost; but that it should be with this peculiarity, that the authority should not pass from Him to another, notwithstanding He confers it, this is what he learnt there. And whence do we prove that John did already know that the Lord was to baptize with the Holy Ghost; so that what he must be understood to have learned by the dove is, that the Lord was to baptize with the Holy Ghost in such wise that the authority should not pass from Him to any other man? Whence do we prove this? The dove descended after the Lord was baptized; but before the Lord came to be baptized by John in the Jordan, we have said that John knew Him, on the evidence of those words, in which he says, "Comest Thou to me to be baptized? I have need to be baptized of Thee." Well, he did know Him to be the Lord, knew Him to be the Son of God; how do we prove that he knew already that the same was He who should baptize with the Holy Ghost? Before He came to the river, whilst many people were running together to John to be baptized, he says to them, "I indeed baptize you with water; but He that cometh after me is greater than I, the latchet of whose shoes I am not worthy to loose; the same shall baptize you with the Holy Ghost, and with fire." Already he knew this also. What then did he learn from the dove, that he may not afterwards be found a liar (which God forbid we should think), if it be not this, that there was to be a certain peculiarity in Christ, such that, although many ministers, be they righteous or unrighteous, should baptize, the virtue of baptism would be attributed to Him alone on whom the dove descended, and of whom it was said, "This is He that baptizeth with the Holy Ghost"? Peter may baptize, but this is He that baptizeth; Paul may baptize, yet this is He that baptizeth; Judas may baptize, still this is He that baptizeth.

For if the sanctity of baptism be according to the diversity of merits in them that administer it, then as merits are diverse there will be diverse baptisms; and the recipient will imagine that what he receives is so much the better, the better he appears to be from whom he received it. The saints themselves-understand brethren, they that belong to the dove, that have their part in that city of Jerusalem, the good themselves in the Church, of whom the apostle says, "The Lord knoweth them that are His"-are endued with different graces, and do not all possess like merits. Some are more holy than others, some are better than others. Therefore if one receive baptism from him, for example, who is a righteous saint, another from another who is of inferior merit with God, of inferior degree, of inferior continence, of inferior life, how notwithstanding is that which they receive one, equal and like, if it be not because, "This is He that baptizeth"? Just, then, as when the good and the better administer baptism, one man does not receive a good thing, another a better; but, notwithstanding that the ministers were one good the other better, they receive what is one and equal, not a better in the one case and a worse in the other; so, too, when a bad man administers baptism, through the ignorance or forbearance of the Church (for bad men either are not known as such, or are borne with; the chaff is tolerated until the floor be fully purged at the last), that which is given is one, not unlike because the ministers are unlike, but like and equal because "This is He that baptizeth."

The dove teaches us. From the head of the Lord she answers, and says, Thou hast baptism, but the charity with which I groan thou hast not. How is this says he, I have baptism, and have not charity? Have I the sacraments, and not charity? Do not shout: show me how can he who divides unity have charity? I, saith he, have baptism. Thou hast; but that baptism, without charity, profits thee nothing; because without charity thou art nothing. The baptism itself, even in him who is nothing, is not nothing. Baptism, indeed, is something, aye, something great, for His sake, of whom it is said, "This is He that baptizeth." But lest thou shouldst fancy that that which is great can profit thee aught, if thou be not in unity, it was after He was baptized that the dove descended, as if intimating, If thou hast baptism, be in the dove, lest what thou hast profit thee not. Come, then, to the dove, we say; not that thou mayest begin to have what thou hadst not before, but that what thou didst have may begin to profit thee. For thou didst have baptism to destruction without; if thou shalt have it within, it begins to profit thee to salvation.

For not only was baptism not profitable to thee, and not also hurtful. Even holy things may be hurtful. In the good, indeed, holy things are to salvation; in the evil, to judgment. For we certainly know, brethren, what we receive, and what we receive is at any rate holy, and no one says that it is not: and what says the apostle? "But he that eateth and drinketh unworthily, eateth and drinketh judgment to himself." He does not say that the thing itself is bad, but that the evil man, by receiving it amiss, receives the good thing which he does receive to judgment. Was that morsel which the Lord delivered to Judas evil? God forbid. The physician would not give poison; it was health the physician gave; but by unworthily receiving it, he who received it not being at peace, received it unto destruction. So likewise also good heed to what thou hast: by that very thing which thou hast thou wilt be condemned. Wherefore? Because thou hast what belongs to the dove apart from the dove. If thou hast what is the dove's in the dove, thou art safe. Suppose thyself a soldier: if thou hast thy general's mark within the lines, thou servest in safety; but if thou hast it out of bounds, not only that mark will not be of advantage to thee for service, but thou wilt even be punished as a deserter. Come, then, come, and do not say, I have already, I have enough. Come; the dove is calling thee, calling thee by her sighing.
