Origen

The genus of Antichrist is one, the species many, just as all lies are of one sort. As all the holy Prophets were Prophets of the true Christ, so understand that each false Christ shall have his own false Prophets, who shall preach as true the false teachings of some Antichrist. When then one shall say, Lo, here is Christ, or lo, there, we need not look abroad out of the Scriptures, for out of the Law, the Prophets, and the Apostles, they bring the things which seem to favour their lie. Or by this, Lo, here is Christ, or lo, there, they shew that it was not Christ, but some impostor under the same title, such for example as Marcion, or Valentinus, or Basilides taught.
