Christian Apologetics and Research Ministry

Here is a great website with more than 400 pages of answers to questions about Christianity: Christian Apologetics and Research Ministry (CARM)

I found it today via Googling for information contrasting Christianity and Islam.

Interested in that topic (Islam)? CARM has a plethora of helpful articles on Islam!

Other main topics:

1. Atheism
   
2. Jehovah Witnesses
   
3. Mormanism
   
4. Evolution
   
5. Roman Catholicism
   
6. Kabbalah
