The Pilgrims themselves were separatist Puritans, Protestant Christians who separated from the Church of England. They sought to practice Christianity as was done in the times of the Apostles. Following Martin Luther's and John Calvin's Reformation, they believed that the Bible was the only true source of religious teaching and that any additions made to Christianity had no place in Christian practice, especially with regard to church traditions such as clerical vestments or the use of Latin in church services. In particular, they were strongly opposed to the Anglicans' episcopal form of church government. They believed that the church was a community of Christians who made a covenant with God and with one another. Their congregations had a democratic structure. Ministers, teachers, and lay church elders were elected by and responsible to the entire congregation (Calvinist Federalism). Each congregation was independent of all the others and directly subject to Christ's government (theocracy), hence the name Congregationalism. The Pilgrims distinguished themselves from another branch of Puritans in that they sought to "separate" themselves from the Anglican Church, rather than reform it from within. It was this desire to worship from outside of the Anglican Communion that led them first to the Netherlands and ultimately to New England.
