The Catholic Priest: St. Alphonsus de Liguori

... in obediance to the words of his priests--Hoc est Corpus Meum--God himself descends on the altar, that he comes wherever they call him, and as often as they call him, and places himself in their hands, even though they should be his enemies. And after having come, he remains, entirely at their disposal; they move him as they please, from one place to another; they may, if they wish, shut him up in the tabernacle, or expose him on the altar, or carry him outside the church; they may, if they choose, eat his flesh, and give him for the food of others.
