You are correct, the Pastafarian movement is small today. This is no impediment. Christianity began with a prophet and a few apostles. Mormonism began with just Joseph Smith; Christian Science started with just Mary Baker Eddy. Pat Robertson started out small, and today gets $130 million per year. Being small at the beginning leads to rich rewards later.
There are no credible sources. In this regard, Pastafarians are like the Discovery Institute, and 'intelligent design'. The Flying Spahetti Monster movement is based on the creed that "we don't need no friggin' evidence, we just make it up as we go along."
However, the Pastafarian faith is attracting adherents and growing at three (3) times the rate of Southern Baptists.
It would be inappropriate for me to speak on behalf of the personal beliefs of other Pastafarians, but in general we recognize unintelligent design when we see it, and we have little faith in either ancient scripts or theories of eternity.
May I ask what evidence is available to support your faith? Also, do you speak seriously or in jest? In regard to the latter I tend to think the latter, in which case your comments have little if anything to do with real life.
