It is in fact true that there are very deep and powerful relationships between mythology and Christianity.
The priesthood in ancient Egypt was called the 'Melchizedeks'. According to the bible Abraham met Melchizedek. Melchizedek 'had no beginning and no end'.
The Edgar Cayce material states that Melchizedek was an appearance of the Christ spirit.
There are other similarities between ancient Egyptian mysticism and Christianity.
I believe now that Jesus Christ was in India and Egypt during all of those 'missing years' that aren't recorded in the bible. Cayce confirms this also.
Christ was also initiated into those ancient mysteries.
Cayce said the Egyptian god Thoth was a living form of 'the word'. Perhaps this means Thoth is Christ I'm not sure.
Moses was raised as an Egyptian and was also initiated into that secret priesthood.
So we see that the bible mainly provides a perspective of a certain time frame and the experiences of a specific group of people. But there were many important and relevevant things that happened before that time.
Many people who are experts in the bible don't understand these relationships. This gives them a narrow and myopic understanding of philosophy.
