Doulos:
If you'd like to find out more about Reformed Baptists here's a good article:

"What is a Reformed Baptist"
http://www.prbc.org/ReformedBaptist.htm

and a good audio by James White:

"Why I am a Reformed Baptist"

P.S. No Reformed Baptists that I know of think we're the Original Church. That's Landmarkism, which again you're more likely to find in an Independent, Fundamental, Old-Fashioned, King James Only Baptist Church (there's actually one with that designation just up the road from me).
