The Father shared His Spirit with His Son.

Yes The Father also shared His Spirit with all His Sons.

In the Son the full portion is called the Spirit of Christ.
Putting in your own ideas? …is that wise?

Never two entities but one Spirit and we are invited to join this communion.
Maybe you should smudge this verse out of your bible if you don’t believe what it says…
John 14:23 Jesus answered and said unto him, If a man love me,
he will keep my words: and my Father will love him,
and WE will come unto him,
and make OUR abode with him.

Never two entities
“WE” is two entities, Nick
