The bill passed in May, but its execution was deferred till August; and in the interval the Presbyterian party in the royal Council struggled hard to obtain from the king a suspension of its provisions by the exercise of his prerogative. Charles had promised this, but the bishops were resolute to enforce the law; and on St. Bartholomew's Day, August the 24th, the last day allowed for compliance with its requirements, nearly two thousand rectors and vicars, or about a fifth of the English clergy, were driven from their parishes as Nonconformists. No such sweeping alteration in the religious aspect of the Church had ever been seen before. The ecclesiastical changes of the Reformation had been brought about with little change in the clergy itself. Even the severities of the High Commission under Elizabeth ended in the expulsion of a few hundreds. If Laud had gone zealously to work in emptying Puritan pulpits his zeal had been to a great extent foiled by the restrictions of the law and by the growth of Puritan sentiment in the clergy as a whole. A far wider change had been brought about in the expulsion of Royalist clergy from their benefices during the Civil War; but the change had been gradual, and had been at least ostensibly wrought for the most part on political or moral rather than on religious grounds. The parsons expelled were expelled as "malignants," or as unfitted for their office by idleness or vice or inability to preach. But the change wrought by St. Bartholomew's Day was a distinctly religious change, and it was a change which in its suddenness and completeness stood utterly alone. The rectors and vicars who were driven out were the most learned and the most active of their order. The bulk of the great livings throughout the country were in their hands. They stood at the head of the London clergy, as the London clergy stood in general repute at the head of their class throughout England. They occupied the higher posts at the two Universities. No English divine save Jeremy Taylor rivalled Howe as a preacher. No parson was so renowned a controversialist or so indefatigable a parish priest as Baxter. And behind these men stood a fifth of the whole body of the clergy, men whose zeal and labour had diffused throughout the country a greater appearance of piety and religion than it had ever displayed before.
