First of all I'd suggest to change your perception about all religion. Pretend that you are an anthropologist studying human culture. Get rid of your preconceived notions about Christianity.
Since I know you are a Wiccan, I'd suggest you do some work on releasing and forgiving.
My own personal views on Christianity is that Christian fundamentalism is propaganda created by the Romans as a political move way back when. Jesus was an Essene. They killed him and perverted his teachings since they couldn't destroy the spirit of Christ.
Good luck with your writing. It sounds interesting. I suggest focusing on the homosexual aspect only. It gets so deep. One topic is enough to write an entire book.
