Finding quality sites regarding religious studies can be quite an ordeal. Over the last few years, I have had the chance to come across some quality sites that can really help in doing either research on a religious subject, or just to learn about specific topics. As I come across more, I will add them here as well. Each link will open in a new window/tab.
Religious Forums: One of the best religious forums I have come across. I am active in the discussions and debates there under the name fallingblood. There are a lot of intelligent and helpful individuals there, and it is a great place to learn more about religion in general.
Early Christian Writings: A great source to read various books that were not accepted into the Biblical Canon as well as writings from other early Christians.
The Bible’s Buried Secrets (PBS): An overview of the origins of the Hebrew Bible.
NT Gateway: A wonderful web directory of internet resources on the New Testament.
