(7) And as they were eating, Jesus took bread, and (l) blessed [it], and brake [it], and gave [it] to the disciples, and said, Take, eat; (m) this is my body.
(7) Christ who will without delay fulfil the promises of the old covenant, institutes a new covenant with new signs.
(l) Mark says, "Had given thanks": and therefore blessing is not a consecrating with a conjuring type of murmuring and power of words: and yet the bread and the wine are changed, not in nature but in quality, for without doubt they become tokens of the body and blood of Christ, not of their own nature or force of words, but by Christ his institution, which must be recited and laid forth, that faith may find what to lay hold on, both in the word and in the elements.
(m) This is a figure of speech which is called metonymy: that is to say, the giving of one name for another: so he calls the bread his body, which is the sign and sacrament of his body: and yet nonetheless, it is a figurative and changed kind of speech meaning that the faithful do indeed receive Christ with all his gifts (though by a spiritual means) and become one with him.
