why have beliefs changed?

Have u ever wondered why there are so many problems in the world centered around faith? Where we stand in our general beliefs, it has broken so many churches, formed a lot of others, created so many factions in different churches and even created new beliefs. Have you ever wondered why a long time ago all that mattered was your name and where you were from and right now so many other things come into play especially religion. Once upon a time you could tell a lot from another person by their dressing, their speech, and basically where they were from now it is virtually impossible. Have you ever wondered why all the vices practiced in the old days, vices like drinking, smoking, drugs, sex and a lot others haven't changed? But people keep finding whole new ways to worship God, whole new meanings to the bible some even twist the Christian faith to suit themselves and I ask myself why? Smoking and drugs may have been refined but its still done the same way, drinking is most definitely done in the same way, the world still refers to kamasutra, gay people are still gay so why are we changing things read in the bible, why are we changing the way we treat God, God hasn't changed, He is still the same God of yesterday, he will be the same God tomorrow
