Each town in the colony was considered a single church congregation; in later years, some of the larger towns split into two or three congregations. Church attendance was mandatory for all residents of the colony, while church membership was restricted to those who had converted to the faith. In Plymouth Colony, it seems that a simple profession of faith was all that was required for acceptance. This was a more liberal doctrine than the congregations of the Massachusetts Bay Colony, where it was common to conduct detailed interviews with those seeking formal membership. There was no central governing body for the churches. Each individual congregation was left to determine its own standards of membership, hire its own ministers, and conduct its own business.
