For a long time, due to a lack of episcopal supervision, puritans such as William Brewster were able to implement practices they favored in their local communities. In Scrooby, Brewster and fellow puritans met in what was called a conventicle, where they prayed together, discussed the meaning of sermons they had heard and of the scripture, and shared their religious experiences. When the church authorities began to crack down on conventicles and ceremonial nonconformity, puritans faced the choice of obeying the authorities and working to reform the church from within, or separating and setting up their own, illegal, churches. Brewster and those gathered around him chose the latter course and bound themselves together by covenant as a new congregation. Joining them were the clergymen Richard Clifton and John Robinson, who had been deprived of their church posts.
