Christianity has a huge influence on our culture and references to it come up in many literary and philosophical texts. Not to mention I really enjoy a lot of the stories like David and Golaith, Adam and Eve, Abraham and his Son for their philosophical merits. I grew up in a non-Christian home and didn't have any real exposure to Christianity. Also I am an atheist so I am not really looking for literature "preaches but explains to me about the history and teaching of the religion.
What texts can you recommend for someone starting out to learn about Christianity from an academic perspective? Also there are many bibles out there can you give me flavor of the "core" bibles and what they focus on and the style and context in which they are written? Thanks in advance.
