He was ordained, and held a living at Sampford Peverell in Devon. After the outbreak of the English Civil War in 1642, he ventured to express opinions that he had thought it prudent to conceal up to that time. In 1643 he was invited to form a congregation at Coventry.
On his arrival Richard Baxter, who was then chaplain to the rebel forces in the town, challenged him to a controversy.
