“It is not idea supported in the Scriptures.”
From the post I pinged you to earlier:
The union of the names of the Father, Son and the Holy Spirit proves they are equal one with another. It would be absurd to place the Father and two “inferior” created beings with the name of the Father in this solemn rite.
Mat_28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
2Co_13:14 The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Ghost, be with you all.
Isa_48:16 Come ye near unto me, hear ye this; I have not spoken in secret from the beginning; from the time that it was, there am I: and now the Lord GOD, and his Spirit, hath sent me.
That Jesus is literally God, there is no question of it:
Mat_1:23 Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.
That the Father and Son are distinct, and yet one God, cannot be questioned:
Joh 8:17-18 It is also written in your law, that the testimony of two men is true. (18) I am one that bear witness of myself, and the Father that sent me beareth witness of me.
Joh_10:30 I and my Father are one.
God Speaking in the Old Testament:
Isa_41:4 Who hath wrought and done it, calling the generations from the beginning? I the LORD, the first, and with the last; I am he.
Isa_44:6 Thus saith the LORD the King of Israel, and his redeemer the LORD of hosts; I am the first, and I am the last; and beside me there is no God.
Jesus Christ speaking in the new, calling Himself by the same name.
Rev_1:17 ... Fear not; I am the first and the last:
Rev_22:13 I am Alpha and Omega, the beginning and the end, the first and the last.
Rev_1:8 I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.
That the Holy Spirit is God, and not an inanimate “force,” cannot be questioned:
1Co_3:16 Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?
Act_13:2 As they ministered to the Lord, and fasted, the Holy Ghost said, Separate me Barnabas and Saul for the work whereunto I have called them.
Joh_14:26 But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
This idea is very well supported by the scriptures.
Whether absurd or not in your view is not decisive so we'll move on to whether using terms, (father,son, holy spirit are not names), together makes them equal.
No more than using Abraham,Isaac and Jacob together makes all three equal.
The Father has a name, the Son has a name but name the holy spirit.
“Mat_1:23 Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.”
The angels instructed Mary and Joseph to name their firstborn Jesus not Emmanuel and Jesus was never referred to by that name. Evidently Matt. 1:23 means something other than people would use Emmanuel as a proper name for Jesus.
Most Jewish names had a meaning such as “Jah is Lord” but the person so named was not being called God.
