As a matter of interest, why do you apply this faith based reasoning for your religion, when you would not use it in any other area?
Is is that you like the religion and just want to adopt it?
Because in almost all other areas of my life there is solid evidence of the things that I believe in. Oh, they are not all cut and dried and easy to live with. Justice, politics, relationships.
Religious belief starts, as I see it, from a concept that is impossible to prove, no matter how hard some might try to do so, the existance of the deity applicable to their particular choice of religion.
I believe that my deities exist, I believe the Summerlands exist, I believe in the Cycle of Life - birth, life, death and re-birth.
I do not ask anyone to change their religious, agnostic or atheist views because I don't follow them and I do not, and neither does any Pagan or Witch that I know personally, proselytise. You want to know about my beliefs, for whatever reason, ask me 'cos I'm not chasing after you to explain them or try to force them upon you.
Not rational? Probably not, but, hey, it works for me.
