The foreign Protestants, whose interference was so manifest in most of the extremer courses taken by the English Reformers, held very strong views as to the unlawfulness of altar crosses, and especially of crucifixes. Writing from Zurich on March 20th, 1560, Peter Martyr says, "to have the image of the Crucifix upon the holy table at the administration of the Lord's Supper, I do not count among things indifferent, nor would I recommend any man to distribute the sacraments with that rite, ... neither Master Bullinger nor myself count such things as matters of indifference, but we reject them as forbidden." "Master Bullinger" speaks for himself in a letter of May 1st, 1566. "I could never approve," he says, "of your officiating, if so commanded, at an altar laden, rather than adorned, with the image of Him that was crucified." The matter was thought sufficiently important to form the subject of a conference, as we learn from a letter written by Jewel, Bishop of Salisbury, to Peter Martyr. "This controversy about the Crucifix," he writes, "is now at its height.... A disputation upon this subject will take place to-morrow. The moderators will be persons selected by the council. The disputants on our side are the Archbishop of Canterbury and Cox; and on the other, Grindal, the bishop of London, and myself." The discussion took place in the spring of 1560, and apparently resulted in favour of the Protestants, although the sympathies of the Queen, as we learn from a letter addressed by Sampson, Bishop of Worcester, to Martyr, were on the other side. The directing force in this iconoclastic movement was evidently Genevan, and it would appear to have been Genevan only, for it is well known that the Lutheran Churches of Germany retain the Crucifix above the altar. In England, also, the attempt was only temporally successful. At the coronation of Charles I. a crucifix was placed on the altar, and the use of at least a cross is now practically universal.
