I don’t think accusing others of psychological problems or purposely trying to mislead adds anything to your posts. You write some interesting information but the bitter tone gets in the way. I don’t accuse you of trying to distort or purposely misquoting. It would be a better exchange, and in general makes for better dialogue if you make the assumption that we are each interested in finding out the truth.
I came across the reference in Tertullian about there being a time when the Son did not exist most recently in the book Christian Beginnings: From Nazareth to Nicaea, AD 30 to 325 (London, Penguin Books: 2013) by Geza Vermes. He makes these further comments on Tertullian:
Tertullian firmly opposed the co-eternity of the Son and endeavoured to demonstrate it in a fashion prefiguring Arius in the age of Nicaea:
‘There was a time when neither sin, nor the Son co-existed with the Deity. Sin made God into a judge, and the Son made him into a Father … Just as he became Father through the Son and judge through sin, so God also became Lord by means of the creatures he had made in order to serve him.’ (Against Hermogenes 3)
Elsewhere, in conformity with earlier tradition, which echoed the New Testament, Tertullian presented Christ as inferior to God the Father. ‘Whatever was the substance of the Word that I designate as a person, I claim it for the name of the Son; and while I recognise the Son, I maintain that he is second to the Father.’ (Against Praxeas 7.9)
