Hippolytus

“ When first the self-existent Father, He who is inconceivable and without substance, He who is neither male nor female, willed that His own ineffability should become realized in something spoken, and that His invisibility should become realized in form, He opened His mouth, and sent forth similar to Himself a Logos. And this (Logos) stood by Him, and showed unto Him who he was, viz., that he himself had been manifested as a (realization in) form of the Invisible One. And the pronunciation of the name was of the following description. ”

“ And that these sounds are those which gave form to the insubstantial and unbegotten Æon, and that those forms are what the Lord declared to be angels—the (forms) that uninterruptedly behold the face of the Father.
Footnotes ↑ Hippolytus has already employed this word, ἁδρομέστερον, in the Proœmium. It literally means, of strong or compact parts. Hippolytus, however, uses it in contrast to the expression λεπτομέρης, in reference to his Summary of Heresies. ”
