Welcome to the party, MO74/Margie!
If you're interested in where to begin regarding Christianity, I'd recommend Acharya's Christ Conspiracy
because it gives quite a broad overview and covers most issues. For an example of that here's a free e-book titled The Origins of Christianity and the Quest for the Historical Jesus Christ
which is a recently updated e-book/excerpt.
Here's a video from an independent film maker who made his own movie which significantly uses Acharya's work titled, Zeitgeist part 1
. It's only about 25 minutes and it's just a brief introduction to Acharya's work in a sense. Here's the thread for that titled, ZEITGEIST Part 1 & The Supportive Evidence
However, those can seem a bit harsh at first to a newbie. Acharya's book titled Who Was Jesus? Fingerprints of The Christ
was written with Christian friends and family in mind so, it's the GENTLE VERSION
. Check out the link and you'll find a video description of the book.
For some really serious scholarship into the influence of the Egyptian religion upon later Christianity, I'd very highly recommend Christ in Egypt: The Horus-Jesus Connection
. That link also contains a brief video description of the book.
And then there's the 37-page e-book titled, Jesus as the Sun throughout History
"Jesus as the Sun throughout History examines ancient texts, including the Bible and works of the early Church fathers, as well as other writings, art, artifacts and traditions to demonstrate that Jesus has been perceived as the sun, both spiritually and as the actual, physical solar orb, many times over the centuries by numerous people, including religious authorities and common people."
Here's a brief excerpt for Jesus as the Sun throughout History
