Christians sit on Christ's Throne.Revelation 3:21 says that those who overcome sit with Jesus on his throne. So Christians sit on the throne of God? No?
You think its heresy because you have difficulty counting up to the number 2. There are 2 Thrones. Can you count up to 2 or is that asking too much for a heretic to do?Don't go too far with Trinitarians philosophy. As you can see, your premise that Jesus sitting on the throne is something that makes him God is heresy.
