William Erbury was born in Glamorganshire, Wales and died in London. He was educated at Brasenose College, Oxford and took his BA in October 1623. He was ordained and became rector of St Mary's Church in Cardiff. He was forced to resign his living in 1638, after the Bishop of Llandaff had pronounced him ‘a schismatical and dangerous preacher’, and after his refusal to submit to ecclesiastical admonition resulted in formal charges being brought against him. He continued to preach in conventicles. In 1640 he became a chaplain in the Parliamentary army, but his extreme heterodoxy (he was variously labelled an Anabaptist, Antinomian, Seeker and Socinian) and the fear that he would corrupt the common soldiers led to his dismissal in 1645. Thereafter he continued to preach and to live on the contributions of friends.
