nothing of the sacrifice, nothing except the visible form of the bread and wine. [Sidenote: Transubstantiation.] But apart from these writers the trend of opinion and inclination told entirely in favour of the materialistic school of thought. To the ordinary folk the miraculous aspect of the doctrine was a positive recommendation to acceptance. And the word Transubstantiation, even though it did not necessarily imply a materialistic change, undoubtedly became associated in men's minds with that idea. As early as the middle of the ninth century Haimo of Halberstadt had said that the substance of the bread and wine (that is, the nature of bread and wine) is changed substantially into another substance (that is, into flesh and blood). But the word "transubstantiate" is used first by Stephen, Bishop of Autun (1113-29), who explains "This is My Body" as "The bread which I have received I have transubstantiated into My Body." Sanction was first given for the use of the word in the Lateran Council of 1215. In the confession of faith drawn up by that Council it is asserted that "there is one Universal Church of the Faithful, outside of which no one at all has salvation: in which Jesus Himself is at once priest and sacrifice, whose Body and Blood are truly received in the sacrament of the altar under the form of bread and wine, the bread being transubstantiated by the divine power into the Body and the wine into the Blood, in order that for the accomplishment of the mystery of the unity we may receive of His what He has received of ours. And this as being a sacrament no one can perform except a priest who shall have been duly ordained according to the Keys of the Church, which Jesus Christ Himself granted to the Apostles and their successors." [Sidenote: Resulting Changes.] This "mystery of the unity" became, on the one side, the subject of a long and intricate controversy on the method by which the change in the elements was effected, while on the other side it lent itself to much mystical meditation. Of neither of these is there space to give illustration; but the hymn of St. Thomas Aquinas, which is familiar to English readers under the form of "Now, my tongue, the mystery telling," blends the two sides with astonishing success. It is a mistake to describe the view of the sacrament thus sanctioned by the Church as either more "advanced" or "higher" than the older view. It was merely more elaborate, and as being such it led on to certain definite results or changes in custom. Thus, in the first place, hitherto children had partaken of the sacrament. This had come partly from the teaching of the need of the sacrament for salvation, partly from the early custom of administering communion directly after baptism. The fear of profanation now caused the gradual discontinuance of children's communions, and in the middle of the thirteenth century they were definitely forbidden. [Sidenote: Refusal of cup to laity.]
