You keep failing to tell us what the fundaments are? I feel I am well in touch with the fundamentals of Christianity. I was a Christian for longer than you were likely alive. So when you keep claiming we are just ignorant of the fundamentals and cannot back up the accusation, then you have nothing. It is another claim with zero evidence.<quoted text>
Did Jesus say any of His teachings would be easy to understand? In fact some of the most knowledgable people of the scriptures didn't understand His teachings. It makes total sense that you need to understand the fundamentals before you can understand the deeper doctrines. It really isn't dissimilar to math, or physics, or chemistry. My 6 year old is learning addition and subtraction but is not learning division or multiplication yet, and certainly not algebra.
BTW, I continue to study Christianity even as an atheist.
