I don't see how a discussion about God is breaking a commandment. Writing or uttering His name is not taking His name in vain, but if you do think that, then i can respect that, and we can agree to disagree
I'm also not breaking the First Commandment because Jesus fulfilled the prophecies of the Messiah. I'm not going to list them all, but instead, post this link which explains them. And since this is the basis of my faith, I will not waste my time arguing about what anybody says about Jesus NOT fulfilling Messianic prophecy.You have your beliefs about it, and I have mine.

And about Mohammad... if you can't accept my stance on him, I have no problem refereeing to him as the philosopher Mohammad.
