Chapter 15 — Part I — The Eucharist
Section 316. Q. How was this Sacrament instituted? A. Jesus Christ, immediately before his passion, consecrated it for the first time, exhibiting in it by anticipation a lively image of his sufferings for our salvation; and after having administered it to the Apostles, he gave them at the same time a commandment ever after to perpetuate this Sacrament.
