Agree.Arius was a subordinationist who taught there was a point somewhere between Eternity-Past and 30 AD when the person we now know as Jesus Christ did not exist, at least not as a distinct entity. Not co-eternal, not co-equal. Can't say anything about consubstantial until you postulate ontological existence. Arius even wrote hymns to reinforce his theology. (Nothing like a good song to help people remember your theology, right @St. SteVen?) Co-eternality is what the big kerfluffle in Nicaea with St. Nicolas of Myra allegedly slapping Arius was all about.
John chapter one is so clear on this. The Word (Logos) became flesh. See verse 14.
It does NOT say that the Son became flesh. The Son was NOT the Son until the Word became flesh.
