When I speak of a great journey from this world to the next, from earth to Heaven, you must not understand me to mean that it is a great many miles from earth to Heaven, or that it takes a long time to go to the next world. No. We cannot measure the distance, nor does it take time to get there. The instant we die, no matter where that happens, our soul is in the next world, and judged by God. *259 Q. When are we bound to receive Holy Communion? A. We are bound to receive Holy Communion, under pain of mortal sin, during the Easter time and when in danger of death. *260 Q. Is it well to receive Holy Communion often? A. It is well to receive Holy Communion often, as nothing is a greater aid to a holy life than often to receive the Author of all graces and the Source of all good. *261 Q. What should we do after Holy Communion? A. After Holy Communion we should spend some time in adoring Our Lord, in thanking Him for the graces we have received and in asking Him for the blessings we need. Lesson 24 ON THE SACRIFICE OF THE MASS 262 Q. When and where are the bread and wine changed into the body and blood of Christ? A. The bread and wine are changed into the body and blood of Christ at the consecration in the Mass. 263 Q. What is the Mass? A. The Mass is the unbloody sacrifice of the body and blood of Christ. The Holy Sacrifice is called Mass probably from the words the priest says at the end when he turns to the people and says, "Ite Missa est"; that is, when he tells them the Holy Sacrifice is over. *264 Q. What is a sacrifice? A. A sacrifice is the offering of an object by a priest to God alone, and the consuming of it to acknowledge that He is the Creator and Lord of all things. "Sacrifice." From the very earliest history of man we find people--for example, Abel, Noe, etc.--offering up sacrifice to God; that is, taking something and offering it to God, and then destroying it to show that they believed God to be the Master of life and death, and the Supreme Lord of all things. These offerings were sometimes plants or fruits, but most frequently animals.
