“when it comes to God, you attach an awe-inspiring solemnity to him, a transcendence of every substance and nature. What constitutes the unique nature of God’s deity, so to say, you ascribe to the Father but then rob the Son of it and make him subordinate. You give the Son a second level in quality and worship. Even if you endow him with the syllables which make up the word “similar,” you in fact truncate his Godhead, and make a mischievous transition from an homonymity maintaining equality to one connecting unequals.”
― Gregory of Nazianzus, On God and Christ: The Five Theological Orations and Two Letters to Cledonius
