Hebrews 1:10: You have given just one example of Scriptural passages that Trinitarians twist to suit their unstable reasoning, peacedog.
Paul quotes here from Psalm 102:25,26 and its contextual application to YHWH. The Hebrew readers are not Trinitarians but SEVERE monotheistic Jews. Nothing in these verses would have prepared a Hebrew reader for the extraordinary idea that the Son was in fact THE GOD, or that Jesus was the YHWH of the Hebrew Scriptures.
It is completely illogical the writer would suddenly assert such a thing without adequate preparation to Biblically-aware Monotheistic Jews.
Go back in your reading to verse 7: there are three types here, Angels, The Son, and THE LORD (YHWH) (Hence my request that you explain Psalm 110:1). Those who had been following the writer would have no reason to assume that the Lord of Psalm 102 was the Son himself. It would be obvious to any Jewish reader that this "LORD" is the Creator YHWH himself.
The previous quotation had proven that the Messiah (The Anointed One) was exalted only over his "partners" (companions), NOT GOD. Indeed the Son has his own "God." This could never be said of "ho THEOS" The God, for He has no God himself. (Deuteronomy 10:17)
It goes without saying that a Jewish reader, reading without explanatory explanation, would have no difficulty in understanding that with the breat "and" in verse 10, the subject has moved to YHWH, Jehovah as Psalm 102 has it.
Typical of Trinitarian translators, some have added phrases to "and" indicating the "Son" of verse 8 is in fact YHWH of Psalm 102. The Greek does not allow for this!! Such a translation must be considered a Trinitarian paraphrase ignoring the context.
So, rather than bait Debator, Peacedog... research the dishonesty of the Trinitarian translator and put the Scriptures into the context and mind of the original reader.
You will be amazed how warped some translators are. The worst example is 1 John 5:7.. look it up in Wikepedia.
The Trinity is a Chaldean/Babylonian heresy introduced by corrupt priests and endorsed by a Pagan convert Constantine into church doctrine at the Confernce of Nicea in 325. It has no place in Judeo-Christian theology.
Fancy doing back flips through your own hoops now, Peacedog???
