congregational ecclesiology is not overwhelming. Robert Browne (1550–1633) was the first person to set out explicit congregational principles and is considered the founder of Congregationalism. While studying for ordination, Browne became convinced that the Church of England was a false church. He moved to Norwich and together with Robert Harrison formed an illegal Separatist congregation. In 1581, Browne and his followers moved to Holland in order to worship freely. While in Holland, Browne wrote treatises that laid out the essential features of Congregationalism. Browne argued for a church only of genuine, regenerate believers and criticized the Anglicans for including all English people within their church. The congregation should choose its own leaders, and the ministers should be ordained by the congregation itself not by bishops or fellow ministers. Each congregation should be founded on a written church covenant, and the congregation as a whole should govern the church: "The meetings together… of every whole church, and of the elders therein, is above the apostle, above the prophet, the evangelist, the pastor, the teacher, and every particular elder" and "The voice of the whole people, guided by the elders and the forwardest, is said [in Scripture] to be the voice of God". While each church would be independent, separate churches would still come together to discuss matters of common concern. Short lifespans were typical of Separatist churches (also known as Brownist congregations). These were small congregations who met in secret and faced persecution. They were often forced to go into exile in Holland and tended to disintegrate quickly. Notable Separatists who faced exile or death included Henry Barrow (c. 1550–1593), John Greenwood (died 1593), John Penry (1559–1593), Francis Johnson (1563–1618), and Henry Ainsworth (1571–1622). In the early 1600s, a Separatist congregation in Scrooby was founded through the efforts of John Smyth (who later rejected infant baptism and became a founder of the Baptist movement). John Robinson was the congregation's pastor and William Brewster was an elder. In 1607, the congregation moved to Holland fleeing persecution. In 1620, the group (known in history as the Pilgrims) sailed to North America on the Mayflower, establishing the Plymouth Colony and bringing the Congregational tradition to America. In 1639 William Wroth, then Rector of the parish church at Llanvaches in Monmouthshire, established the first Independent Church in Wales "according to the New England pattern", i.e. Congregational.
