All for His Glory?

I was in my friend's room the other day, and we were talking how they were going to go to Sunday service for Palm Sunday (they're Catholic but don't go to church). Eventually we got into the discussion about the differences between protestants and catholics. Catholic bible had more books, they have a Pope, priests vs. pastors, etc. After a while, one guy in the room was just like "whatever, who cares about the differences- we're all worshiping the same God anyway". We all just responded with an unsure "yeaaaaah..." kind of thing.

This got me wondering about denominations and different religions. I know I've asked this before, but it does still make me wonder if different religions are just severe denominations. Like...if you REALLY think about it, the Protestant, Catholic, Jewish, and even the Islamic God are the same...in origin anyway. Everyone at least has the Old Testament in common. The very major differences come within the New Testament. I know that I'm Christian and the difference is that we're supposed to acknowledge and accept Jesus Christ as our Saviour. But I can't help but to wonder what all of this is for other religions (or denominations). I found it interesting how Islam scripture says that all who worship the same god (Muslims, Jews, and Christians alike) will be saved in the end. It's so easy to just write off everyone else sometimes because I know what the answer should be- sometimes I kind of wish I didn't have this Christian bias at hand. No, I'm not questioning my faith- I'm just not good at balancing academics and personal belief.

I don't really have a point. Just some food for thought.
