it is not anti-oneness to say that GOD is distinguished from JESUS. The bible does do this many times. It is understood in such cases that GOD refers to the Father, just like GOD THE FATHER is in the bible but GOD THE SON is not. It is distinguishing sonship from fatherhood.
Rev 22 shows GOD AND THE LAMB after
Rev 5 shows the LAMB going to the ONE on the throne. This is oneness! It's just that some folks never really understood that oneness does not deny a difference between offices of Son and Father, but denies a difference of PERSONS.
