Whatever you call yourself there should be a historical record of those who hold the same beliefs as you do from the time of the Apostles to the present. If there's not, you should be asking yourself some questions.
I call myself a christian. There is an historical record. Its in the book of Acts where its recorded they were first called christians in Antioch. I didn't get my name from some dude in 110 ad who made a statement about the church being catholic (universal). Remember, he was using "catholic" as a verb then. You've made it a noun. You're the one easily duped. You should be askin' yourself questions.
There is good evidence for many Protestant doctrines from the time of the first century. The hang-up for you is that there is not a continuation of those early beliefs to the present. The interesting thing is that if there is support for the Proddie beliefs in the 1st century why should we have to prove that they existed in the middle? Shouldn't that make for some interesting questions for you? Why haven't you continued in the doctrines and practices of the church of the first century? Why haven't you continued in baptism by immersion (which was the preferred method from the earliest documents we have)? Why don't you speak in tongues?
You view this as a continuity thing. We see it as a restoration thing.
