How can you say Christianity isn't a religion? While you were looking in Webster's you should have found this:
Main Entry: Chris·tian·i·ty
Pronunciation: \ˌkris-chē-ˈa-nə-tē, ˌkrish-, -ˈcha-nə-, ˌkris-tē-ˈa-\
Function: noun
Date: 14th century
1 : the religion derived from Jesus Christ, based on the Bible as sacred scripture, and professed by Eastern, Roman Catholic, and Protestant bodies
2 : conformity to the Christian religion
3 : the practice of Christianity
Don't get me wrong, I'm not taking issue with you or your beliefs, I just don't see how you are describing anything other than a religion. And for the record, I am a Christian.
