He next pours down upon us a heap of names, saying that he knows of the existence of certain Simonians who worship Helene, or Helenus, as their teacher, and are called Helenians. But it has escaped the notice of Celsus that the Simonians do not at all acknowledge Jesus to be the Son of God, but term Simon the “power” of God, regarding whom they relate certain marvellous stories, saying that he imagined that if he could become possessed of similar powers to those with which be believed Jesus to be endowed, he too would become as powerful among men as Jesus was among the multitude.
But neither Celsus nor Simon could comprehend how Jesus, like a good husbandman of the word of God, was able to sow the greater part of Greece, and of barbarian lands, with His doctrine, and to fill these countries with words which transform the soul from all that is evil, and bring it back to the Creator of all things. Celsus knows, moreover, certain Marcellians, so called from Marcellina, and Harpocratians from Salome, and others who derive their name from Mariamme, and others again from Martha.
We, however, who from a love of learning examine to the utmost of our ability not only the contents of Scripture, and the differences to which they give rise, but have also, from love to the truth, investigated as far as we could the opinions of philosophers, have never at any time met with these sects. He makes mention also of the Marcionites, whose leader was Marcion.
