But Marcion, of Pontus, and Cerdon, [1051] his preceptor, themselves also lay down that there are three principles of the universe -- good, just, and matter. Some disciples, however, of these add a fourth, saying, good, just, evil, and matter. But they all affirm that the good (Being) has made nothing at all, though some denominate the just one likewise evil, whereas others that his only title is that of just. And they allege that (the just Being) made all things out of subjacent matter, for that he made them not well, but irrationally. For it is requisite that the things made should be similar to the maker; wherefore also they thus employ the evangelical parables, saying, "A good tree cannot bring forth evil fruit," [1052] and the rest of the passage. Now Marcion alleges that the conceptions badly devised by the (just one) himself constituted the allusion in this passage. And (he says) that Christ is the Son of the good Being, and was sent for the salvation of souls by him whom he styles the inner than. And he asserts that he appeared as a man though not being a man, and as incarnate though not being incarnate. And he maintains that his manifestation was only phantastic, and that he underwent neither generation nor passion except in appearance. And he will not allow that flesh rises again; but in affirming marriage to be destruction, he leads his disciples towards a very cynical life. And by these means he imagines that he annoys the Creator, if he should abstain from the things that are made or appointed by Him.
