More than one in purpose. The Glory of oneness was gifted to Him by God for in Him all the fullness of the Fathers Deity dwells.
Don’t you believe that I am in the Father, and that the Father is in me? The words I say to you I do not speak on my own authority. Rather, it is the Father, living in me, who is doing his work.
The Father is the true God and is greater than all. In a manner of speaking the Son is the begotten God and it's the Deity of the First and last in Him not another Deity. Two persons, One Deity.
But about the Son who is one with God in the Deity that lives in Him without limit. He is all that the Father is. (Mighty God in this context)
The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word.
The image of the invisible God
A begotten Son, (His spirit), who is and was chosen before all things in the form of God for God's fullness lives in Him.
And God has placed all things, even our very lives, in the hands of His anointed one so that only in regard to His own throne is His authority greater. God's Christ has sovereign authority.
One God our Father and One Christ our Lord -just two persons
