Smyth, convinced that his self-baptism was invalid, applied with the Mennonites for membership. He died while waiting for membership, and some of his followers became Mennonites. Thomas Helwys and others kept their baptism and their Baptist commitments. The modern Baptist denomination is an outgrowth of Smyth's movement. Baptists rejected the name Anabaptist when they were called that by opponents in derision. McBeth writes that as late as the 18th century, many Baptists referred to themselves as "the Christians commonly—though falsely—called Anabaptists."
