This is heresy.
You have perverted Scripture.
The Father and the Holy Spirit are NOT names "Jesus". Jesus was only named Jesus after He was born as man.
John 5:43 means that when Jesus said He came in His "Father's name" - it DOESN'T mean they have the same name. It means that He came by the Father's AUTHORITY.
This is similar to a knight proclaiming, "I come in the name of the King!"
It doesn't mean that the Knight and the King have the SAME name. He came by the AUTHORITY of the King.
Isaiah 9:6 foretold, "For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his
NAME shall be called Wonderful, counsellor, The Mighty God, The Everlasting Father, The Prince of Peace."
Deuteronomy 6:4 clearly tells us ... "
Hear, O Israel: the LORD our God is one LORD:"
Therefore, compare the following references:

Jesus tells us in Revelation 22:16
I Jesus have sent mine angel to testify unto you these things in the churches. I am the
root and the offspring of David, and the bright and morning star.
God Bless!
