You are seriously embracing the Albigensians/Cathars as Protestant Christians?
Nah. I guess the RC church was right in slaughtering them. < /sarcasm>
Sometimes Protestants, in their overeagerness to distance themselves from Rome, do adopt any non-Catholic group out there. When I was still involved in the Plymouth Brethren, I remember reading a book trying to trace the unbroken line of Brethren-like churches throughout history. I knew that I was reading shoddy history as soon as I saw them extolling the Montanists as a worthy example for the church to emulate - apparently ignorant that Montanus claimed to be the Paraclete and that his wife Priscilla was Jesus Christ reincarnate.
