Your wishful heretical thinking does not override what's actually revealed in Rev 3:21.
Tell us more about how the Unitarian Jesus vacates his Throne.... I'll get the popcorn!
Nope. The Christians reside on Jesus' Throne. Why don't you believe Rev 3:21 when it reveals that there are 2 Thrones?
Rev 3:21 says that Jesus sat down with His Father
in His Father's Throne and that proves that the Father's "Right Hand" is not amputated away metaphorically, positionally, or any other way you want to spin it.
Rev 5:8 And when he had taken the book, the four beasts and four and twenty elders
fell down before the Lamb, having every one of them harps, and golden vials full of odors, which are the
prayers of saints.
