Religion

I began reading this artical on 6 different types of religions. The more I read the more distraught I became on the whole religion thing. Religion has never really given me much thought. I am a Christian- that's my "religion". A lover and a follower of Christ.
As I continued reading this artical, the more I thought about it... Why do we have all these 'religions'? The artical was on Southern Baptist, Presbyterian, Methodist, Episcopal, Assembly of God, and Roman Catholic. Six different religions, all (if I'm not mistaken) classified as Christians. For some reason this really upset me. Since when are Christians suppose to be divided??? I became aware of the face that I have no idea what my church is. Could there be a church that doesn't classify itself as one of the six mentioned, and just be a church for Christians?
I remember awhile ago someone asking me what religion I am. When I answered 'I'm a christian" they looked at me like that wasn't an anwer. They said something like "no, i mean, what are you- Baptist? Catholic?..." If I remember right, the person who asked me this was not a christian. Or if they were they didn't attend a church. I wonder if this is why Christianity confused so many non-belivers and Agnostics.
There is one heaven. One God. One savor. One spirit. One Bible (even though it is interpreted in many different versions). So what is the point of having so many different religions? If we all believe in the same God, and follow the same word, and desire to one day live with our God in Heaven, then why do we split ourselves up? Does that mean only one religion is right? If we are all going to be united as a family in Heaven, shouldn't we come together here on Earth, to love each other. Arn't we all suppose to be one body of Christ? I believe if we all came together, it would be one more step toward changing this world, and help prepare us for eternity.

This is just a thought I wanted to share. I'm not judging anyone for their religion, its just a curious observation of mine.
