In 1686, he was offered an invitation by a local Nonconformist minister to move to Chester, England and establish a congregation. He was initially hesitant to accept, not wanting to take away members from an already established minister but upon Harvey's insistence he accepted. Henry was ordained on 9 May 1687 by a group of six Nonconformist ministers. He presented a paper written in Latin as part of his ordination. He then became minister of a new Presbyterian congregation at Chester. The congregation grew under his leadership and in 1699 he oversaw the construction of a new building. While in Chester, Henry founded the Presbyterian Chapel in Trinity Street. After becoming established in Chester, he began to travel around to nearby cities speaking. He became a member of the local Chester union of ministers. Henry said of living in Chester "I cannot think of leaving Chester, until Chester leaves me."
