I'll share quotes with you below.
The first are from The Pagan Christ: Is Blind Faith Killing Christianity? (Allen & Unwin) by Tom Harpur.
"The very thing which is now called the Christian religion
existed among the ancients also, nor was it wanting from
the inception of the inception of the human race until the coming of Christ
in the flesh, at which point the true religion , which was
already in existence, began to be called Christian."
-- St. Augustine, Retractiones
"But we have the treasure in earthen vessels."
-- St. Paul, 2 Corinthians
"Do you know that you are the temple of God ,
and that the Spirit of God dwells in you."
-- 1 Corinthians 3 : 16
"My point, once again, is not that those ancient people
told literal stories and we are now smart enough to take
them symbolically, but that they told them symbolically
and we are now dumb enough to take them literally."
-- John Dominic Crossan, Who Is Jesus?
The other book I'm reading at the moment is The Hero With a Thousand Faces by Joseph Campbell. The following quote is from this book.
