8 But that they are said to have the same God the Father as we, to know the same Christ the Son, the same Holy Spirit, can be of no avail to such as these. For even Korah, Dathan, and Abiram knew the same God as did the priest Aaron and Moses. Living under the same law and religion, they invoke the one and true God, who was to be invoked and worshipped; yet, because they transgressed the ministry of their office in opposition to Aaron the priest, who bad received the legitimate priesthood by the condescension of God and the ordination of the Lord, and claimed to themselves the power of sacrificing, divinely stricken, they immediately suffered punishment for their unlawful endeavours; and sacrifices offered irreligiously and lawlessly, contrary to the right of divine appointment, could not be accepted, nor profit them.
Even those very censers in which incense had been lawlessly offered, lest they should any more be used by the priests, but that they might rather exhibit a memorial of the divine vengeance and indignation for the correction of their successors, being by the command of the Lord melted and purged by fire, were beaten out into flexible plates, and fastened to the altars, according to what the Holy Scripture says, “to be,” it says, “a memorial to the children of Israel, that no stranger which is not of the seed of Aaron come near to offer incense before the Lord, that he be not as Korah.” And yet those men had not made a schism, nor had gone out abroad, and in opposition to God's priests rebelled shamelessly and with hostility; but this these men are now doing who divide the Church, and, as rebels against the peace and unity of Christ, attempt to establish a throne for themselves, and to assume the primacy, and to claim the right of baptizing and of offering.
How can they complete what they do, or obtain anything by lawless endeavours from God, seeing that they are endeavouring against God what is not lawful to them? Wherefore they who patronize Novatian or other schismatics of that kind, contend in vain that any one can be baptized and sanctified with a saving baptism among them, when it is plain that he who baptizes has not the power of baptizing.
