According to Trinitarians, did the stature of the Eternal Logos get diminished?

Trinitarians assert that Jesus is the Eternal Word of God. From John 1 they assert personified pronouns in order to claim this chapter supports this idea. This assertion of ambiguous Greek pronouns can be discussed and debated at length. However, in the context of this question, let us assume Jesus is actually the personified Eternal Word of God. Furthermore, let us assume every theoretical detail of the Trinity. I often ask Trinitarians why God(Jesus) has a God(the Father) and the response is that the human _part_ of Jesus _has a_ God, but the divine _part_ of him _does not_ have a God because he is God. The common Trinitarian belief is that Jesus began to have a God when he took on flesh. He currently still has his flesh (now glorified) and is still a man. This Jesus then, is now and forever fully man and _not only_ fully God Almighty as he was eternally with the Father. This God-man _has_ a God now and forever who he will serve into eternity as high priest. The Risen Son is not a high priest to himself. Heb 2 >16 For indeed he does not give aid to angels, but he does give aid to the seed of Abraham. 17 Therefore, in all things ***he had to be made like his brethren, that he might be a merciful and faithful High Priest*** in things pertaining to God, to make propitiation for the sins of the people. 18 For in that he himself has suffered, being tempted, he is able to aid those who are tempted. Heb 7:20 > And it was not without an oath! Others became priests without any > oath, 21 but he became a priest with an oath when God said to him: > > “The LORD(YHWH) has sworn > and will not change his mind: > ***‘You are a priest forever.’***” Heb 8 >1 Now this is the main point of the things we are saying: We have such a High Priest, who is seated at the right hand of the throne of the Majesty in the heavens, 2 a **Minister** of the sanctuary and of the true tabernacle which the Lord erected, and not man. > >3 For every high priest is **appointed to offer** both gifts and sacrifices. Therefore it is necessary that this One also have something to offer. 4 For if he were on earth, he would not be a priest, since there are priests who offer the gifts according to the law; 5 who serve the copy and shadow of the heavenly things, as Moses was divinely instructed when he was about to make the tabernacle. For He said, “See that you make all things according to the pattern shown you on the mountain.” 6 But now he has obtained a more excellent **ministry**, inasmuch as he is also Mediator of a better covenant, which was established on better promises. Jesus was glorified and exalted beyond the angels... beyond every creature to ever exist. But this Eternal person, the *Logos*, seems to have been diminished in stature to that of a servant/minister of God (high priest) instead of his former status as fully God Almighty. **My questions**: 1. How do Trinitarians understand this change in stature and place of the *Logos* within the Kingdom of God? 2. How do Trinitarians make a case that his stature was not diminished, when formally he was not subordinate to anyone?
