Circular reasoning is starting with a conclusion and then finding what you need to back up the conclusion.
The Word that became flesh in John 1:1-15 is the wisdom of Proverbs 8.
As to Hebrews 1:8, you and other pick up on the first line and ignore the second line and then do not read Psalm 45 to get the context of what was quoted, which is what a Jew would do.
Psalms 45:1-7
My heart overflows with a good theme;
I address my verses to the King;
My tongue is the pen of a ready writer.
2 Thou art fairer than the sons of men;
Grace is poured upon Thy lips;
Therefore God has blessed Thee forever.
3 Gird Thy sword on
Thy thigh, O Mighty One, In Thy splendor and Thy majesty!
4 And in Thy majesty ride on victoriously,
For the cause of truth and meekness and righteousness;
Let Thy right hand teach Thee awesome things.
5 Thine arrows are sharp;
The peoples fall under Thee;
Thine arrows are in the heart of the King's enemies.
6 Thy throne, O God, is forever and ever;
A scepter of uprightness is the scepter of Thy kingdom.
7 Thou hast loved righteousness, and hated wickedness;
Therefore God, Thy God, has anointed Thee
With the oil of joy above Thy fellows.
NAS
Deuteronomy 6:4 reads "Behold O' Israel! YHWY is our elohiym, YHWY is echad. Yehova is our god, Yehova is one. Now, since echad is the Hebrew cardinal number one to interpret God as a compound unity is ludicrous.
Isaiah 9:6 tells the
name of a child to be born will be Wonderful Counselor (the Holy Spirit), Eternal God and Mighty Father (God, the Father), and Prince of Peace (the Son). This verse can and has been used by the Jesus only cult since it better describes their belief than the Trinity since all the titles are in one name not three persons.
Now move forward to the NT where Jesus uses the phrase "My name" (again not My person) 23 times. And in Philippians 2:9 (and other verses) where we are told it is at the name of Jesus (not the person of Jesus) that every knee will bow.
Put Revelation 1:8 in context starting at vs. 4:
Revelation 1:4-8
4 John to the seven churches that are in Asia: Grace to you and peace, from Him who is and who was and who is to come; and from the seven Spirits who are before His throne; 5 and from Jesus Christ, the faithful witness, the first-born of the dead, and the ruler of the kings of the earth. To Him who loves us, and released us from our sins by His blood, 6 and He has made us to be a kingdom, priests to His God and Father; to Him be the glory and the dominion forever and ever. Amen. 7 Behold, He is coming with the clouds, and every eye will see Him, even those who pierced Him; and all the tribes of the earth will mourn over Him. Even so. Amen.
8 "I am the Alpha and the Omega," says the Lord God, "who is and who was and who is to come, the Almighty."
NAS
Verse 8 is referring to God, not the Lord Jesus Christ.
Revelation 1:17 needs to be understood in the context of the whole word of God. Paul wrote:
1 Timothy 6:13-16
13 I charge you in the presence of God, who gives life to all things, and of Christ Jesus, who testified the good confession before Pontius Pilate, 14 that you keep the commandment without stain or reproach until the appearing of our Lord Jesus Christ, 15 which He will bring about at the proper time-- He who is the blessed and only Sovereign, the King of kings and Lord of lords; 16 who alone possesses immortality and dwells in unapproachable light; whom no man has seen or can see. To Him be honor and eternal dominion! Amen. NAS
This is a description of God, the Father not the Lord Jesus Christ.
Jesus is the first and last in God's plan of salvation for mankind, but this verse does not establish Jesus is God.
Taken in full context, which is what this thread is attempting to accomplish the Bible does not teach Jesus is God.
Now, this is the last time I will warn you. The purpose of this thread is to track the Messianic prophecies and how Jesus fulfilled them and in so doing teach us that Jesus is not God. You have repeatedly tried to take this thread off track. The next time you try your account will be terminated. Have I made myself clear?
