"When the Master himself has explicitly said of the bread, 'This is my body,' will anyone still dare to doubt? When He is Himself our warranty, saying, "This is my blood," who will ever waver and say it is not His Blood?"

These the two final catechetical lectures given by Cyril to catechumens around 349 A.D are termed the Mystagogical Lectures. In them, Cyril instructs the newly baptized on the mysteries into which they had just been initiated: baptism, confirmation, and the Eucharist. He reserves his lectures on the Eucharist for last, to "crown the work" of his pupils' spiritual edification.
