Is there a central Christian authority? Is someone sitting on Peter's throne with the unquestioned authority to determine whether or not a belief is Christian or not?
By your logic, I'd expect to see you preparing for conversion to Catholicism.
There is no Biblical basis for Peter having a Throne on Earth. The only earthly throne mentioned in Scripture is the Throne of David, which at the present time appears to be sitting vacant. In light of God's covenant with the Jews, why do you think that the Throne of David is vacant right now?
