"Most important was Tyndale's Bible translation...which gave currency to Erasmian and Lutheran revisions of such crucial established concepts as ecclesia (church or congregation?) and presbyter (priest or elder?), and which was accompanied by powerfully reformist prefaces and prologues. Tunstall's attempt to stamp out this dangerous New Testament had greatly amused the reformers who financed further operations out of the money the bishop paid over in buying up the offending edition. In 1528 Tyndale also entered the lists as a theorist of politics when in his Obedience of a Christian Man he elaborated Luther's teaching on the subject's duty of submission to his secular ruler in ways highly satisfactory to Henry who read the book with pleasure; next year, however, Tyndale cast himself into outer darkness again by violently attacking the Divorce in a work, The Practice of Prelates, mainly concerned to blast Wolsey and the English hierarchy in general."
