Anyone who believes that Jesus Christ was the Son of God, believing that Christ was born of the Virgin Mary, was crucified and rose again on the third day, paying for our sins with HIS blood, accepts Him as Savior and FOLLOWS Him is a Christian. The Christian religion is further broken into different denominations: Catholicism, Methodism, the Baptists, Lutherans, etc.
Though some denominations include the word "Christian" in their name, "Christian" is not a denomination in and of itself. Instead, Christianity refers to the entire body of believers, and a denomination is a smaller autonomous group within the body, defined by its governing body, hierarchy, or shared belief system. Because Baptists are not governed by a hierarchical system as are some denominations, Baptists are classified by their shared distinctive beliefs, such as local church autonomy, priesthood of the believer, and believers' baptism.
Baptists, therefore, technically do not consider themselves as a denomination, by virtue of the autonomy of the local church.
