The struggle between the old principles and the new continued, notwithstanding all Henry's attempts to secure unanimity. As early as 1540 a set of questions had been circulated amongst the bishops, and as a result of the replies received and of the discussions that took place in Convocation a book was issued, entitled /A Necessary Doctrine and an Erudition for any Christian Man/ (1543). It was issued by order of the king, and for this reason is known as the /King's Book/ in contradistinction to the /Bishop's Book/, published with his permission but not by his authorisation. Just as the /Bishop's Book/ represented a revision of the Ten Articles, so the /King's Book/ was an extension or completion of the /Bishop's Book/, in many respects even more Catholic in its tone than the original. The king was now nearing his end rapidly, and both parties in the royal council strove hard for mastery. Gardiner and Bonner, Bishop of London, stood firm in defence of Catholic doctrine, and once or twice it seemed as if they were about to succeed in displacing Cranmer from the favour of the king; but the danger of an attack from the united forces of France and the Emperor, especially after the peace of Crépy had been concluded (1544), made it necessary for Henry not to close the door against an alliance with the Protestant princes of Germany by an attack on Cranmer, who was regarded by them as an active sympathiser. Once indeed Henry ordered that the archbishop should be arrested, but a sudden change of mind took place, and the order for the arrest was cancelled.
