Baptists hold their services of worship on
Sunday and first-day Sabbatarianism has been the dominant position among Baptists. However, there is a group known as the
Seventh Day Baptists whose origins are derived from
Anabaptism and the pre-Reformation. Seventh Day Baptists gather and worship on the seventh day of the week on Saturday. A large portion of Seventh Day Baptists adopted the teachings of the Sabbath, which led to the formation of the
Seventh-day Adventist Church. Baptists are descendants of the
Separatists who, according to some, were probably influenced by Continental Anabaptists, like other Dissenters. Thus the Baptist tradition is considered an outcome of the
Reformation. In the early 17th century, those individuals who called themselves Baptists dissented from
the Church of England. Some notable Puritan dissenters included
John Smyth and
Thomas Helwys who were acknowledged as key pioneers for the Baptist denomination. Furthermore, some Baptists (notably
Landmarkists or "Baptist Bride" adherents) hold to a belief in
perpetuity, which embraces the notion that the Baptists, under various names, have existed since the time of Christ until today as the Church of Christ founded in Jerusalem was Baptist. Those who believe in this Baptist perpetuity, view the Baptist tradition as not being a critical aspect of the Protestant Reformation. == Baptist theologians ==
