The "God" aspect is a part of religion and a religion is a "belief" of that "God". True believers of a religion base their God on faith for that is how it is meant to be. However the question is awkwardly lopsided only because if no one had any faith there wouldnt be a religion. So to base one agaisnt the other is like asking which didn't come last, the egg or the chicken?
