JoenB75 said: "Also God made the Son heir of all things and gave him All authority. He
must be worshipped as Jesus Christ the highest authority in the
universe. He is not making an argument that All things have exceptions or
that the Son is a creature. The Son is the Word made flesh, a specific
mode of God revealed to reconcile / finish creation."
Your comment about the Son being "a specific mode of God" rhymes with "modalistic monarchianism," a doctrinal belief from the late 2nd and 3rd century. The term "modalism" was first said to be used by theologian Arnold von Arnack to describe the belief that God manifests himself in various "modes" through the Son and the Holy Spirit. By the way, modalism was generally considered a heresy by early Trinitarians. Modalism is not a biblical belief.
Your statement, "He
[the Son] must be worshipped as Jesus Christ the highest authority in the
universe" needs to be qualified. First, Heb. 1.6 calls on angels to worship Jesus, as many Bible versions put it. However, it should be noted that the biblical term can mean anything from a simple act of physical inclination as a token of respect, to one of full adoration. Context determines the right interpretation of the word.
Is Jesus "the highest authority in the universe"? No, all authority was given to him. If he was already almighty being a "mode of God," it would not be necessary for someone else to give him authority. The same with knowledge. God doesn't need to receive factual information from another because he himself is all-knowing. Yet, Rev. 1.1 shows God giving the heavenly Christ a "revelation" to pass on to others. The text you quoted of 1 Cor. 15.28 itself shows that Jesus is second to God in the universal scheme of things. And yes, Paul stated clearly that the concept of "all things" (Gk: pánta) submitting to Christ EXCLUDES God. Thus, if Christ is subject to God forever, it is reasonable to believe that his own life was caused by God, as Jesus himself claimed. (John 6.57) These biblical concepts counter the factuality of the idea that Christ is ‘the maximum authority in the universe.’
Jesus himself asked others to worship the Father, not him. (John 4.23,24) The rightful conclusion would be one in accord with Paul, who stated that "God is the head of Christ." (1 Cor. 11.3) I would rather believe in Jesus Christ hlmself who said "the Father was greater than him, instead of accepting human doctrines pushed by modalists such as Praxeas, Noetus and Sabellius.
In fact, Jesus did not even foresee a moment in his future Kingdom where he would have enough authority to assign favored seats to others. He said only the Father had that prerogative. (Matt. 20.20-23) Thus, the Son is scripturally shown to have some limitations. (Matt 24.36; Acts 1.6,7)
