Greetings again BB1956,
The only begotten Son of God was the first being directly created by the only True God YHWH, then through his only begotten Son, YHWH God created the angels, and then the physical universe and all the life on planet earth, especially human life.
I appreciate your explanation of your perspective and you seem to have covered the JW perspective in a clear and detailed manner. Instead of answering every detail of your Post, I would like to give a general explanation of my perspective, and also respond to a few of your details.
I believe that our Lord Jesus Christ was and is a human, now exalted and now sitting on the right hand of the One God, Yahweh, God the Father and Jesus will soon return to sit upon the Temple Throne of David in Jerusalem and he will reign over a converted, significant remnant of natural Israel and over the mortal nations and individuals that survive the Battle of Armageddon.
Jesus is the Son of God by birth as God the Father is his father and Mary his mother, refer Matthew 1:20-21 and Luke 1:34-35. Jesus Christ is the Son of God by character, he was full of grace and truth John 1:14. He is also the Son of God by resurrection, and his resurrected body was changed from a mortal human, to a glorious immortal human, similar to that depicted in the Transfiguration.
I would like to concentrate on the character of Jesus. Was he sinless, was he full of grace and truth because in a previous life he was Michael the Archangel, or God the Son?
John 1:14 (KJV): And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
Where I differ with both JWs and Trinitarians, I attribute "only begotten of the Father" is speaking of his human birth as detailed in Matthew 1:20-21 and Luke 1:34-35. Was the human character and sinlessness of Jesus a development or a transfer of the character of Michael the Archangel or God the Son into the human body of Jesus? The Scriptures reveal that his wisdom was developed:
Luke 2:40,52 (KJV): 40 And the child grew, and waxed strong in spirit, filled with wisdom: and the grace of God was upon him. 52 And Jesus increased in wisdom and stature, and in favour with God and man.
Isaiah 11:1–5 (KJV): 1 And there shall come forth a rod out of the stem of Jesse, and a Branch shall grow out of his roots: 2 And the spirit of the LORD shall rest upon him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and of the fear of the LORD; 3 And shall make him of quick understanding in the fear of the LORD: and he shall not judge after the sight of his eyes, neither reprove after the hearing of his ears: 4 But with righteousness shall he judge the poor, and reprove with equity for the meek of the earth: and he shall smite the earth with the rod of his mouth, and with the breath of his lips shall he slay the wicked. 5 And righteousness shall be the girdle of his loins, and faithfulness the girdle of his reins.
Isaiah 50:4–9 (KJV): 4 The Lord GOD hath given me the tongue of the learned, that I should know how to speak a word in season to him that is weary: he wakeneth morning by morning, he wakeneth mine ear to hear as the learned. 5 The Lord GOD hath opened mine ear, and I was not rebellious, neither turned away back. 6 I gave my back to the smiters, and my cheeks to them that plucked off the hair: I hid not my face from shame and spitting. 7 For the Lord GOD will help me; therefore shall I not be confounded: therefore have I set my face like a flint, and I know that I shall not be ashamed. 8 He is near that justifieth me; who will contend with me? let us stand together: who is mine adversary? let him come near to me. 9 Behold, the Lord GOD will help me; who is he that shall condemn me? lo, they all shall wax old as a garment; the moth shall eat them up.
None of the above attribute his character to a pre-existent Michael the Archangel or God the Son, but to his special birth and development as a human, and hence the phrase "the only begotten of the Father" relates to what is revealed in Matthew 1:20-21 and Luke 1:34-35.
In both these cases the word, "archangel" is singular, suggesting that only one angel bears this title.
I suggest that Michael the Archangel is an Angel and is an Angel of the One God, Yahweh, God the Father as the Scriptures state. From the following it appears that there were a number of Archangels, each given a different area of responsibility. They stood in the Presence of God, and in contrast Jesus is now seated at the right hand of God. Gabriel is one of these Archangels:
Daniel 10:12–13 (KJV): 12 Then said he (Gabriel) unto me, Fear not, Daniel: for from the first day that thou didst set thine heart to understand, and to chasten thyself before thy God, thy words were heard, and I am come for thy words. 13 But the prince of the kingdom of Persia withstood me one and twenty days: but, lo, Michael, one of the chief princes, came to help me; and I remained there with the kings of Persia.
If the writer to the Hebrews considered Jesus to be Michael the Archangel, then he would not state the following:
Hebrews 1:4–7,13-14 (KJV): 4 Being made so much better than the angels, as he hath by inheritance obtained a more excellent name than they. 5 For unto which of the angels said he at any time, Thou art my Son, this day have I begotten thee? And again, I will be to him a Father, and he shall be to me a Son? 6 And again, when he bringeth in the firstbegotten into the world, he saith, And let all the angels of God worship him. 7 And of the angels he saith, Who maketh his angels spirits, and his ministers a flame of fire. 13 But to which of the angels said he at any time, Sit on my right hand, until I make thine enemies thy footstool? 14 Are they not all ministering spirits, sent forth to minister for them who shall be heirs of salvation?
