And that is why denying the full divinity of the Son—even under the guise of "order" or "will"—is not a harmless speculation, but a fatal error.
Yet from 1st John-
'22 Who is the liar? It is whoever denies that Jesus is the Christ. Such a person is the antichrist—denying the Father and the Son. 23 No one who denies the Son has the Father; whoever acknowledges the Son has the Father
further in John's letter-
14 And we have seen and testify that the Father has sent his Son to be the Savior of the world. 15 If anyone acknowledges that Jesus is the Son of God, God lives in them and they in God.'
Then, according to this scripture, to acknowledge that Jesus is the Son of God is sufficient.
Further attested by Jesus himself-
'15 “But what about you?” he asked. “Who do you say I am?”
16 Simon Peter answered, “You are the Messiah, the Son of the living God.”
17 Jesus replied, “Blessed are you, Simon son of Jonah, for this was not revealed to you by flesh and blood, but by my Father in heaven.'
No additional explanation of the extent of his divinity (as we may or may not understand it) is required.
