Some also believe the Baptists got their start from the Anabaptists. However, this is unlikely, due to the fact that Baptists and Anabaptists disagree on many issues (such as practices and doctrines relating to church discipline and pacifism).
Another view known as Landmarkism teaches that the first Baptists were the discples of St. John the Baptist. This, however, is extremely unlikely as Baptism espouses many doctrines that developed either in post-schism Catholicism or in other Protestant sects, more than a millennium after Christ. The most notable denomination that holds this view is the American Baptists.
