Catena Aurea · Matthäusevangelium 26
And as they were eating, Jesus took bread, and blessed it, and brake it, and gave it to the disciples, and said, Take, eat; this is my body. PSEUDO-DIONYSIUS. (Eccl. Hier. 3. in fin.) In this is also shewn, that the one and uncompounded Word of God came to us compounded and visible by taking human nature upon Him, and drawing to Himself our society, made us partakers of the spiritual goods which He distributed, as it follows, And gave to his disciples.
(de Sacr. iv. 5.) Before consecration, it is bread; after Christ’s words, This is my body, have been pronounced, it is Christ’s Body.
