Note 312 — Chapter IX · POST-CHRISTIAN GNOSTICS: VALENTINUS
Reading edition
Ἦν, φησίν, ἐν αὐτῷ τῷ σπέρματι Υἱότης, τριμερὴς κατὰ πάντα, τῷ οὐκ ὄντι θεῷ ὁμοούσιος, γενητὴ ἐξ οὐκ ὄντων, Hippolytus, op. cit, Bk VII. c. 22, p. 349, Cruice. If these are Basilides’ actual words, he would seem to have been the first author to make use of the expression Homoousios.
