The Catechism of the Catholic Church

The Catechism has spent considerable time unpacking Holy Communion—the “sacrament of sacraments”—with us, and now she summarizes the most essential truths that we must internalize and move forward with. Fr. Mike takes this “nugget day” to tell us that God desires to feed us. He has given us his Son so that we might be filled with him and made whole again, in unity with him for all of eternity. Today’s readings are Catechism paragraphs 1406-1419.

The Catechism wraps up its overview of the Eucharist by reminding us that the sacrament of Holy Communion is a foretaste of what is to come in heaven. Fr. Mike exhorts us to prepare our hearts here on earth so that they might be conformed to God, ready to unite with him forever in heaven. The Eucharist is a most excellent path to such unity. Today’s readings are Catechism paragraphs 1402-1405.

The sacrament of Holy Communion unites the faithful together in a most profound, visible way. It also makes disunity in the Church all the more painful and apparent. The Catechism reveals the Church’s teachings regarding the Eucharist and Christian churches who are not in full communion with the Catholic Church. Fr. Mike addresses a most common and difficult question: “If a non-Catholic believes that the Eucharist is truly Jesus, why can they not receive him in the sacrament?” Today’s readings are Catechism paragraphs 1396-1401.

As the popular adage goes, “you are what you eat.” The Catechism tells us that, as food nourishes the body, so Jesus present in Holy Communion nourishes the soul. It especially highlights the Eucharist’s role in separating us from sin. Fr. Mike reminds us we must be open to change if Jesus is going to change us in the reception of Holy Communion. If—to use Fr. Mike’s analogy—Holy Communion is a “shower” of graces, we must ensure that we’re not wearing a raincoat. Today’s readings are Catechism paragraphs 1391-1395.

The Catechism goes over the prerequisites to receiving Jesus in the Eucharist, as well as how often the faithful can and should receive him. Fr. Mike ensures that we understand the gravity of our obligation to go to the sacrament of Reconciliation before receiving Communion. As St. Paul said, “Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of profaning the body and blood of the Lord.” Today’s readings are Catechism paragraphs 1384-1390.

We continue our examination of the sacrament of the Eucharist, specifically how we worship the Eucharist. Fr. Mike examines how we, as Catholics, worship the true and real presence of Christ in the Eucharist. He emphasizes how incredibly important the worship of Christ in the Eucharist is, specifically in Adoration. Today’s readings are Catechism paragraphs 1378-1383.

Together, with Fr. Mike, we explore the reality of Christ’s true presence in the Eucharist. Fr. Mike unpacks what actually happens during the celebration of the sacrifice of the Eucharist, specifically, transubstantiation. He explains that during the Consecration, the whole substance of bread and wine becomes the whole substance of the Body and Blood of Christ. Today’s readings are Catechism paragraphs 1373-1377.

Together, we continue our exploration of the sacrificial memorial of the sacrament of the Eucharist. Fr. Mike reiterates that the whole Church, both visible and invisible, is united in the Sacrifice of the Eucharist. He also further unpacks the importance of a quote from St. Ignatius of Antioch, which states that the offering of the sacrifice of the Eucharist must be united with the apostolic succession of our Pope and bishop. Today’s readings are Catechism paragraphs 1369-1372.

We continue our examination of the sacrament of the Eucharist. Fr. Mike emphasizes that every element of Christ’s passion, the whole thing, is one, single sacrifice, and when we celebrate the Mass, we are participating in that same sacrifice. He also reiterates that the Eucharist is both a noun and a verb. It “re-presents” the sacrifice of the Cross. Today’s readings are Catechism paragraphs 1362-1368.

Together with Fr. Mike, we continue our examination of the sacrament of the Eucharist. Fr. Mike takes us back to the Book of Genesis, the sacrifices of Cain and Abel, and the Book of Exodus, the story of Moses and Pharaoh. He emphasizes that the point of freedom in life is to be led to the freedom to worship God and that it matters to God that we freely choose to attend the Holy Sacrifice of the Mass. Today’s readings are Catechism paragraphs 1356-1361.
