It was not until the twenty-fifth and last session of the Council of Trent, in 1563, that the assembled Fathers made reference to the arts, and that only in very general terms: ‘The Council forbids placing in churches any image which illustrates false doctrine and can mis-lead the simple … it forbids placing in any church even if it is not subject to diocesan visitation, any unusual image, unless it has been approved by the bishop’. The Council recommended the retention of images in churches, but otherwise its decree was purely negative. It did not contemplate using religious art as one of the weapons of controversy in its war against Protestantism. That was to come later.
