You mean to say you see apostolic succession, papal infallility, and a host of other noxious dogmas in that one simple statement? Hardly.
Papal infallibility, absolutely!
What part of "Whatever you declare bound on Earth shall be bound in Heaven; whetever you declare loosed on Earth shall be loosed in Heaven" don't you understand?
As for apostolic succession, the role of a Regent is to remain in office until the King returns. It doesn't do much good to appoint a regent when the King will be gone for thousands of years, but the Regent will also be gone in a few short years. Power to confer a successor regent until the return of the King is part of what being a regent is.
How useless a regent would be if, once he were killed, there would be no one to rule the Kingdom? And why bother reporting that the office of regent was established, if it were quickly to be disbanded? Indeed, we do see that when the apostles lost one of their members, they did choose a successor. If anything, we need a Regent 2,000 years later far more desperately than the early Christian communities did. Thank God we have one!
