"For many of our Catholics the Eucharist is above all a meal deriving mainly from the Last Supper on Holy Thursday, and not so much a sacrifice that embraces the whole Paschal Mystery. An in-depth catechesis on the Eucharist as a sacrifice should be imparted to our people who would be able to understand it well in the light of their traditional beliefs."
