23. What, then, is to be made of what is written, "Abstain from strange water, and drink not from a strange fountain," if, leaving the sealed fountain of the Church, you take up strange water for your own, and pollute the Church with unhallowed fountains? For when you communicate with the baptism of heretics, what else do you do than drink from their slough and mud; and while you yourself are purged with the Church's sanctification, you become befouled with the contact of the filth of others? And do you not fear the judgment of God when you are giving testimony to heretics in opposition to the Church, although it is written, "A false witness shall not be unpunished? " But indeed you are worse than all heretics. For when many, as soon as their error is known, come over to you from them that they may receive the true light of the Church, you assist the errors of those who come, and, obscuring the light of ecclesiastical truth, you heap up the darkness of the heretical night; and although they confess that they are in sins, and have no grace, and therefore come to the Church, you take away from them remission of sins, which is given in baptism, by saying that they are already baptized and have obtained the grace of the Church outside the Church, and you do not perceive that their souls will be required at your hands when the day of judgment shall come, for having denied to the thirsting the drink of the Church, and having been the occasion of death to those that were desirious of living. And, after all this, you are indignant!
24. Consider with what want of judgment you dare to blame those who strive for the truth against falsehood. For who ought more justly to be indignant against the other?-whether he who supports God's enemies, or he who, in opposition to him who supports God's enemies, unites with us on behalf of the truth of the Church?-except that it is plain that the ignorant are also excited and angry, because by the want of counsel and discourse they are easily turned to wrath; so that of none more than of you does divine Scripture say, "A wrathful man stirreth up strifes, and a furious man heapeth up sins." For what strifes and dissensions have you stirred up throughout the churches of the whole world! Moreover, how great sin have you heaped up for yourself, when you cut yourself off from so many flocks! For it is yourself that you have cut off. Do not deceive yourself, since he is really the schismatic who has made himself an apostate from the communion of ecclesiastical unity. For while you think that all may be excommunicated by you, you have excommunicated yourself alone from all; and not even the precepts of an apostle have been able to mould you to the rule of truth and peace, although he warned, and said, "I therefore, the prisoner of the Lord, beseech you that ye walk worthy of the vocation wherewith ye are called, with all lowliness and meekness, with long-suffering, forbearing one another in love; endeavouring to keep the unity of the Spirit in the bond of peace. There is one body and one Spirit, even as ye are called in one hope of your calling; one Lord, one faith, one baptism; one God and Father of all, who is above all, and through all, and in us all."
25. How carefully has Stephen fulfilled these salutary commands and warnings of the apostle, keeping in the first place lowliness of mind and meekness! For what is more lowly or meek than to have disagreed with so many bishops throughout the whole world, breaking peace with each one of them in various kinds of discord: at one time with the eastern churches, as we are sure you know; at another time with yon who are in the south, from whom he received bishops as messengers sufficiently patiently and meekly not to receive them even to the speech of an ordinary conference; and even more, so mindful of love and charity as to command the entire fraternity, that no one should receive them into his house, so that not only peace and communion, but also a shelter and entertainment, were denied to them when they came! This is to have kept the unity of the Spirit in the bond of peace, to cut himself off from the unity of love, and to make himself a stranger in all respects from his brethren, and to rebel against the sacrament and the faith with the madness of contumacious discord! With such a man can there be one Spirit and one body, in whom perchance there is not even one mind, so slippery, and shifting, and uncertain is it?
26. But as far as he is concerned, let us leave him; let us rather deal with that concerning which there is the greatest question. They who contend that persons baptized among the heretics ought to be received as if they had obtained the grace of lawful baptism, say that baptism is one and the same to them and to us, and differs in no respect. But what says the Apostle Paul? "One Lord, one faith, one baptism, one God." If the baptism of heretics be one and the same with ours, without doubt their faith also is one; but if our faith is one, assuredly also we have one Lord: if there is one Lord, it follows that we say that He is one. But if this unity which cannot be separated and divided at all, is itself also among heretics, why do we contend any more? Why do we call them heretics and not Christians? Moreover, since we and heretics have not one God, nor one Lord, nor one Church, nor one faith, nor even one Spirit, nor one body, it is manifest that neither can baptism be common to us with heretics, since between us there is nothing at all in common. And yet Stephen is not ashamed to afford patronage to such in opposition to the Church, and for the sake of maintaining heretics to divide the brotherhood and in addition, to call Cyprian "a false Christ and a false apostle, and a deceitful worker." And he, conscious that all these characters are in himself, has been in advance of you, by falsely objecting to another those things which he himself ought deservedly to hear. We all bid you, for all our sakes, with all the bishops who are in Africa, and all the clergy, and all the brotherhood, farewell; that, constantly of one mind, and thinking the same thing, we may find you united with us even though afar off.
