Lucius of Castra Galbæ said: Since the Lord in His Gospel said, “Ye are the salt of the earth: but if the salt should have lost its savour, wherewith shall it be salted? It is thenceforth good for nothing, but to be cast out of doors, and to be trodden under foot of men.” And again, after His resurrection, sending His apostles, He gave them charge, saying, “All power is given unto me, in heaven and in earth. Go and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost.” Since, therefore, it is manifest that heretics—that is, the enemies of Christ—have not the sound confession of the sacrament; moreover, that schismatics cannot season others with spiritual wisdom, since they themselves, by departing from the Church, which is one, having lost the savour, have become contrary to it,—let it be done as it is written, “The house of those that are contrary to the law owes a cleansing.” And it is a consequence that those who, having been baptized by people who are contrary to the Church, are polluted, must first be cleansed, and then at length be baptized.
