The term “Pope” is used not only for the Bishop of Rome but also for the Bishop of Alexandria. The term “Methodist” is not used in the bible either, but that doesn’t mean that they are not Christian.
The first time that designation was used for the bishop of Rome is attributed to Damasus in the 4th century. I will agree that many of those in the office of "episkopes" (oversight - I Tim. 3:1) were called "papa", but not with all the rhetorical claims made for that office CENTURIES LATER! The bold statement above is immaterial to anything that I had said...ridiculous of you to even say it!
