For to us a child is born,
to us a son is given,
and the government will be on his shoulders.
And he will be called
Wonderful Counselor, Mighty God,
Everlasting Father, Prince of Peace." Isaiah 9:6
Yes... It says that he will be called "Father." But, its not saying that He IS the Father.
You are missing an important doctrinal detail.
The Father is presently sitting back and allowing Jesus to reign over all creation as God. Reigning until Jesus finishes making his enemies of His humanity
into his footstool. In that sense? The Father is allowing Jesus to be as the 'Father' over all creation!
Jesus is reigning over all creation by proxy as the Father by means of His Deity empowering and enabling Him in all He does!
"Then the end will come, when he hands over the kingdom to God the Father
after he has destroyed all dominion, authority and power. For he must reign until
he has put all his enemies under his feet." 1 Cor 15:24-25
See what that says?
When Jesus finalizes what is needed to finish his work? Then the Father Himself will return to being God over all!
The Father remains being the Father!
The last enemy to be destroyed is death. For he “has put everything under his feet.”
Now when it says that “everything” has been put under him, it is clear that this does
not include God himself, who put everything under Christ. When he has done this,
then the Son himself will be made subject to him who put everything under him,
so that God may be all in all." 1 Cor 15:26-28
So, for now? Jesus is to be called by those in His presence, 'Almighty Father."
For Jesus is now acting on behalf of the Father in all His power of Deity.
The Father is now watching and allowing His Son to do all the work as the Father!
