Do all Christian denominations go by the bible?

Answer 1

The short and simple answer is "no." Many Christian denominations choose to ignore many Bible teachings for various reasons. Some are political reasons, or to do with wealth, or sometimes it's just because they've picked up bad habits over the years from other religions, and have indoctrinated them into their own form of Christianity thus forming a different set of beliefs (denomination). For example, celebrating Christmas is a major one. Christmas has nothing to do with Jesus Christ and it was not until several hundred years after Jesus lived on the earth that people began to commemorate his birth on the 25th of December. However, Jesus evidently was born sometime in October. So why was this date chosen? Some who later claimed to be Christian likely wished the date to coincide with the pagan Roman festival marking the "birthday of the unconquered sun." (The New Encyclopedia Britannica) In winter, when the sun seemed weakest, pagans held ceremonies to get this source of warmth and light to come back from its distant travels. December 25 was thought to be the day that the sun began its return. In an effort to convert pagans, religious leaders adopted this festival and tried to make it seem "Christian." Even if Jesus' disciples had known the exact date of his birth, they would not have celebrated it. Why? Because, as The World Book Encyclopedia says, the early Christians "considered the celebration of anyone's birth to be a pagan custom." Therefore, these customs and many other traditions are not connected with the Bible and mixing with false worship is directly in violation of God's word. "Touch nothing unclean." -Isaiah 52:11. True Christians only commemorate the death of Jesus Christ (Luke 22:19-20). "The person faithful in what is least is faithful also in much, and the person unrighteous in what is least is unrighteous also in much." -Luke 16:10. So your answer is a profound "NO!"
