“For if you have fallen in with some who are called Christians, but who do not admit this [truth], and venture to blaspheme the God of Abraham, and the God of Isaac, and the God of Jacob; who say there is no resurrection of the dead, and that their souls, when they die, are taken to heaven; do not imagine that they are Christians, even as one, if he would rightly consider it, would not admit that the Sadducees, or similar sects of Genistae, Meristae, Gallilleans, Hellenists, Pharisees, Baptists, are Jews (do not hear me impatiently when I tell you what I think), but are [only] called Jews and children of Abraham, worshipping God with the lips, as God Himself declared, but the heart was far from Him. But I and others, who are right-minded Christians on all points, are assured that there will be a resurrection of the dead, and a thousand years in Jerusalem, which will then be built, adorned, and enlarged, [as] the prophets Ezekiel and Isaiah and others declare.”
