Most of the posters are Calvinists, I agree. But the OP was very strongly worded about doctrine not being in line with the historic church. I am simply stating the facts, that Calvinism as we know it today is not any older than 500 years. It does not fit within the time frame of the OP, and would be considered one of those new doctrines that should be rejected. If you want a fair playing field, then that should be considered on the same plane as premillennialism and other such doctrines that are being discussed.
