Saying Christ is the image of God isn’t the same as saying he’s God. It’s referring to his behaviors: holy and righteous. The invisible God is the one called God in this verse. The Father is never called the image of God because He is God.
Same explanation as I said. Yeshua, a man, isn’t an invisible God. It’s referring to his behaviors, doctrines, etc all supplied by God.
John 14:9-10
9Jesus said to him, “Have I been with you so long, and yet you have not known Me, Philip? He who has seen Me has seen the Father; so how can you say, ‘Show us the Father’?
10Do you not believe that I am in the Father, and the Father in Me? The words that I speak to you I do not speak on My own
authority; but the Father who dwells in Me does the works.
Form refers to Greek word morphe. Again it’s the outward appearance.
[the] form
μορφῇ (morphé)
Noun - Dative Feminine Singular
Strong's Greek 3444: Form, shape, outward appearance.
That’s false. I’m afraid many of the Bible versions just obscure the fact that Yeshua isn’t God because they were translated by Trinitarians.
John 17:3
3And this is eternal life, that they may know You,the only true God, and Jesus Christwhom You have sent.
1 Timothy 2:5
5For
there is one God and one Mediator between God and men,
the Man Christ Jesus,
Ephesians 1:3
3Blessed
be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly
places in Christ,
Acts 3:27
27“For truly against Your holy Servant Jesus, whom You anointed, both Herod and Pontius Pilate, with the Gentiles and the people of Israel, were gathered together
And the list goes on. The entire Bible supports the narrative of Yeshua being a man annointed by God to serve Him.
