45. Neither can it be said in this place,[470] Yet who is there that doeth all the words of the Lord which are written in the evangelic sermon itself, at the end of which He says, that he who heard the said words and did them built upon a rock, and he who heard them and did them not built upon the sand? For, granting that by certain persons all the words are not accomplished, yet in the same sermon He has appointed the remedy, saying, "Forgive, and ye shall be forgiven."[471] And after the Lord's prayer had been recorded in detail in the same sermon, He says, "For I say unto you, if ye forgive men their trespasses, your heavenly Father will also forgive you: but if ye forgive not men their trespasses, neither will your Father forgive your trespasses."[472] Hence also Peter says, "For charity shall cover the multitude of sins;"[473] which charity they certainly did not have, and on this account they built upon the sand, of whom the same Cyprian says, that within the Church they held conversation, even in the time of the apostles, in unkindly hatred alien from Christian charity;[474] and therefore they seemed indeed to be within, but really were without, because they were not on that rock by which the Church is signified.
Chap. xxv.—46. Sedatus of Tuburbo[475] said: "Inasmuch as water, sanctified by the prayer of the priest in the Church, washes away sins, just so much does it multiply sins when infected, as by a cancer, with the words of heretics. Wherefore one must strive, with all such efforts as conduce to peace, that no one who has been infected and tainted by heretical error should refuse to receive the one true baptism, with which whosoever is not baptized shall not inherit the kingdom of heaven."
47. To this we answer, that if the water is not sanctified, when through want of skill the priest who prays utters some words of error, many, not only of the bad, but of the good brethren in the Church itself, fail to sanctify the water. For the prayers of many are corrected every day on being recited to men of greater learning, and many things are found in them contrary to the Catholic faith. Supposing, then, that it were shown that some persons were baptized when these prayers had been uttered over the water, will they be bidden to be baptized afresh? Why not? Because generally the fault in the prayer is more than counterbalanced by the intent of him who offers it; and those fixed words of the gospel, without which baptism cannot be consecrated, are of such efficacy, that, by their virtue, anything faulty that is uttered in the prayer contrary to the rule of faith is made of no effect, just as the devil is excluded by the name of Christ. For it is clear that if a heretic utters a faulty prayer, he has no good intent of love whereby that want of skill may be compensated, and therefore he is like any envious or spiteful person in the Catholic Church itself, such as Cyprian proves to exist within the Church. Or one might offer some prayer, as not unfrequently happens, in which he should speak against the rule of faith, since many rush into the use of prayers which are composed not only by unskilful men who love to talk, but even by heretics, and in the simplicity of ignorance, not being able to discern their true character, use them, thinking they are good; and yet what is erroneous in them does not vitiate what is right, but rather it is rendered null thereby, just as in the man of good hope and approved faith, who yet is but a man, if in anything he be otherwise minded, what he holds aright is not thereby vitiated until God reveal to him also that in which he is otherwise minded.[476] But supposing that the man himself is wicked and perverse, then, if he should offer an upright prayer, in no part contrary to the Catholic faith, it does not follow that because the prayer is right the man himself is also right; and if over some he offers an erroneous prayer, God is present to uphold the words of His gospel, without which the baptism of Christ cannot be consecrated, and He Himself consecrates His sacrament, that in the recipient, either before he is baptized, or when he is baptized, or at some future time when he turns in truth to God, that very sacrament may be profitable to salvation, which, were he not to be converted, would be powerful to his destruction. But who is there who does not know that there is no baptism of Christ, if the words of the gospel in which consists the outward visible sign be not forthcoming? But you will more easily find heretics who do not baptize at all, than any who baptize without those words. And therefore we say, not that every baptism (for in many of the blasphemous rites of idols men are said to be baptized), but that the baptism of Christ, that is, every baptism consecrated in the words of the gospel, is everywhere the same, and cannot be vitiated by any perversity on the part of any men.[477]
48. We must certainly not lightly pass over in this judgment that he here inserted a clause, and says, "Wherefore we must strive, with all such efforts as conduce to peace, that no one who has been infected," etc. For he had regard to those words of the blessed Cyprian in his opening speech, "Judging no man, nor depriving any of the right of communion if he entertain a different view." See of what power is the love of unity and peace in the good sons of the Church, that they should choose rather to show tolerance towards those whom they called sacrilegious and profane, being admitted, as they thought, without the sacrament of baptism, if they could not correct them as they thought was right, than on their account to break that holy bond, lest on account of the tares the wheat also should be rooted out,[478]—permitting, so far as rested with them, as in that noblest judgment of Solomon, that the infant body should rather be nourished by the false mother than be cut in pieces.[479] But this was the opinion both of those who held the truer view about the sacrament of baptism, and of those to whom God, in consideration of their great love, was purposing to reveal any point in which they were otherwise minded.
Chap. xxvi.—49. Privatianus of Sufetula[480] said: "He who says that heretics have the power of baptizing should first say who it was that founded heresy. For if heresy is of God, it may have the divine favour; but if it be not of God, how can it either have or confer on any one the grace of God?"
50. This man may thus be answered word for word: He who says that malicious and envious persons have the power of baptizing, should first say who was the founder of malice and envy. For if malice and envy are of God, they may have the divine favour; but if they are not of God, how can they either have or confer on any one the grace of God? But as these words are in the same way most manifestly false, so are also those which these were uttered to confute. For the malicious and envious baptize, as even Cyprian himself allows, because he bears testimony that they also are within. So therefore even heretics may baptize, because baptism is the sacrament of Christ; but envy and heresy are the works of the devil. Yet though a man possesses them, he does not thereby cause that if he have the sacrament of Christ, it also should itself be reckoned in the number of the devil's works.
