The others in the group were William Bridge, Jeremiah Burroughs, Thomas Goodwin and Philip Nye, all with a comparable Dutch background as ministers (Burroughs and Simpson both in Rotterdam.), and united in a form of Congregationalism He was also in the group of ten, dominated by Independents, condemning in 1652 the Racovian Catechism, with Nye and Bridge, six further Independents,John Dury, and Adoniram Byfield.
He became Master of Pembroke Hall, Cambridge in 1650, but was drifting in his last years to the outer extremes in his positions.
