members of one body
It is obvious to believer and unbeliever alike that there are a multitude of Christian traditions. As I have one body with many members, so there are many denominations within one body. You have seen the problems that arise from competition and infighting between denominations. Does this mean that you should forsake denominational affiliation? There is no such thing as a generic Christian. It is beneficial for you to be committed and devout within your own calling. Can you do this without being superior, exclusive, and divisive toward your brothers and sisters who are equally committed and devout within their own traditions?
