The Refutation of All Heresies: Book V. 20The Justinian Heresy Unfolded in the “Book of Baruch.”

But swear, says Justinus, if you wish to know "what eye hath not seen, and ear hath not heard, and the things which have not entered into the heart;" that is, if you wish to know Him who is good above all, Him who is more exalted, (swear) that you will preserve the secrets (of the Justinian) discipline, as intended to be kept silent. For also our Father, on beholding the Good One, and on being initiated with Him, preserved the mysteries respecting which silence is enjoined, and sware, as it has been written, "The Lord sware, and will not repent." Having, then, in this way set the seal to these tenets, he seeks to inveigle (his followers) with more legends, (which are detailed) through a greater number of books; and so he conducts (his readers) to the Good One, consummating the initiated (by admitting them into) the unspeakable Mysteries. In order, however, that we may not wade through more of their volumes, we shall illustrate the ineffable Mysteries (of Justinus) from one book of his, inasmuch as, according to his supposition, it is (a work) of high repute. Now this volume is inscribed Baruch; and one fabulous account out of many which is explained by (Justinus) in this (volume), we shall point out, inasmuch as it is to be found in Herodotus. But after imparting a different shape to this (account), he explains it to his pupils as if it were something novel, being under the impression that the entire arrangement of his doctrine (springs) out of it.
