Parliamentarian rule and the more Protestant ethos of the 1640s led to the removal or destruction of "superstitious" and "idolatrous" images and fittings. Glass painters such as Baptista Sutton, who had previously installed "Laudian innovations", found new employment by repairing and replacing these to meet increasingly strict Protestant standards. In January 1642 Sutton replaced 93 feet of glass at St Magnus and in June 1644 he was called back to take down the "painted imagery glass" and replace it. In June 1641 "rail riots" broke out at a number of churches. This was a time of high tension following the trial and execution of the Earl of Strafford and rumours of army and popish plots were rife. The Protestation Oath, with its pledge to defend the true religion "against all Popery and popish innovation", triggered demands from parishioners for the removal of the rails as popish innovations which the Protestation had bound them to reform. The minister arranged a meeting between those for and against the pulling down of the rails, but was unsuccessful in reaching a compromise and it was feared that they would be demolished by force. However, in 1663 the parish resumed Laudian practice and re-erected rails around its communion table.
