CHAP. XIV.--21. Lucius of Castrum Galbæ[433] said: "Since the Lord hath said in His gospel, 'Ye are the salt of the earth: but if the salt have lost his savour, that which is salted from it shall be thenceforth good for nothing, but to be cast out, and to be trodden under foot of men;'[434] and seeing that again, after His resurrection, when sending forth His apostles, He commanded them, saying, 'All power is given unto me in heaven and in earth: go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost,'[435]--since then it is plain that heretics, that is, the enemies of Christ, have not the full confession of the sacrament, also that schismatics cannot reason with spiritual wisdom, since they themselves, by withdrawing when they have lost their savour from the Church, which is one, have become contrary to it,[436] let that be done which is written, 'The houses of those that are opposed to the law must needs be cleansed;'[437] and it therefore follows that those who have been polluted by being baptized by men opposed to Christ should first be cleansed, and only then baptized." 23. Lucius of Castrum Galbæ has brought forward a proof from the gospel, in the words of the Lord, "Ye are the salt of the earth: but if the salt have lost his savour, that which is salted from it shall be good for nothing, but to be cast out, and to be trodden under foot of men;" just as though we maintained that men when cast out were of any profit for the salvation either of themselves or of any one else. But those also who, though seeming to be within, are yet of such a kind, not only are without spiritually, but will in the end be separated in the body also. For all such are profitable for nothing. But it does not therefore follow that the sacrament of baptism which is in them is nothing. For even in the very men who are cast out, if they return to their senses and come back, the salvation which had departed from them returns; but the baptism does not return, because it never had departed. And in what the Lord says, "Go therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost," He did not permit any to baptize except the good, inasmuch as He did not say to the bad, "Whose soever sins ye remit, they are remitted unto them; and whose soever sins ye retain, they are retained."[438] How then do the wicked baptize within, who cannot remit sins? How also is it that they baptize the wicked whose hearts are not changed, whose sins are yet upon them, as John says, "He that hateth his brother is in darkness even until now?"[439] But if the sins of these men are remitted when they join themselves in the close bonds of love to the good and just, through whom sins are remitted in the Church, though they have been baptized by the wicked, so the sins of those also are remitted who come from without and join themselves by
