The Pa. Dutch folk-culture is divided into two distinct elements: the "Plain" Dutch, who are in the minority, are the Amish & Mennonites: the "Gay" Dutch are, for the most part, Lutheran & Reformed.
The "Plain" Dutch are biblicists: they strictly conform to the Bible & its instructions. Their approach to worship is simple & anti-sacramental. They observe only those Holy Days which are specifically sanctioned in the Bible. They avoid revelry, waste, & "worldly ways": their goal is to be "little & unknown, loved by God alone." With their simple, unadorned, "Plain" way of life, the "Plain" Dutch attempt to separate themselves from the rest of the world.
