John Owen was a leading theologian in 17th-century England. Through his association with Oliver Cromwell in particular, he exercised considerable influence on central government, and became the premier religious statesman of the Interregnum. Crawford Gribben has here produced the most persuasive account ever of a multi-faceted career that ended in deep personal sadness and public failure. Owen was a profound Calvinist thinker who outlived the welcome of most of the millions of words he published, but he was as much a Lord General in the war of ideas as Oliver Cromwell was the Lord General of the clash of swords.
