The following is taken verbatim from the Catechism of Pope St. Pius X:"Q.
What is the matter of the sacrament of the Eucharist?A. The matter of the sacrament of the Eucharist is that which was used by Jesus Christ Himself, that is, wheaten bread and wine of the vine."
"Q.
What is the form of the sacrament of the Eucharist?A. The form of the sacrament of the Eucharist consists of the words used by Jesus Christ Himself 'This is My Body: This is My Blood.'"
