Why are so many religions, even if there is only one Bible?

That's true Bible verse Colossians 2:8. i love kjv that is the Bible we love daily and use. Confusing people about what is true religion. In own learning in the Bible,is the True Church is the Church that teach salvation through Jesus alone and none else.Acts4:12,John3:16,14:6 and Romans 1:16. His Church never preach wrong doctrine,must be base in the scriptures all.His Church means people saved baptized believers and member Jesus local Church,visible.Some religions teach doctrine through their own but not in the Bible base,yes they call God,but their salvation is not base i the scriptures.

Hello :). I believe you have answered your own question by identifying which bible your citation came from. Most religions, including Christianity, are based on interpretations of individuals. This is specifically notable on Christian denominations since they differ from each other to the point in which they made their own bibles for themselves. Different bibles, even if they are based on the same core story, that present different interpretations of the same events means differences in doctrines and rules, as some groups interpret somethings as important and other groups do the same with other things. As to why this happened we have to look at the history of the spreading of Christianity. One of the first separations from the Catholics was the creation of Anglican religion. I have read that it was made by a king who wanted to divorce his wife to secure an heir, how true this is I dunno, but in here we see the changes made to a religion for political purposes. After the "discovery" of the Americas, Spain began to spread the Catholicism to the native populations, but when they found it too hard, they began adopting little parts of the native's religions into the Catholicism they preached to make it easier for them to accept it. That's how you explain the existence of a black Jesus, to give an example. With this you can see variations on the same religion caused by culture and expansion. However these are the easy ones to explain, there are others that are simply based on one individual having a different point of view about what the bible means, and thus making a new version. If other people liked it enough, then it became a new church. I believe this is how the baptist church started, being John Smyth the person recognized for creating it.Like this, every difference can be explained using history, since all variations came to be for a reason, however even if there was only one bible the ways of interpreting it change from person to person, if that is a good or bad thing depends greatly on who is considering it.

Jesus had something interesting to say about this to some religious leaders of his time: [b]"6..."´These people honor me with their lips, but their hearts are far from me. 7 Their worship is a farce, for they teach man-made ideas as commands from God.’ ...13 And so you cancel the word of God in order to hand down your own tradition."[/b] Mark 7 (New Living Translation) "Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ." Colossians 2:8 (King James Version)
