The source and summit of the Christian life, the sacramental center for Catholics, is the holy Eucharist. Like Christ, the holy Eucharist is controversial and divisive. When Jesus initially taught crowds of people about the holy Eucharist, many of them left (see the Gospel of John 6:60). Today, the question still comes to us: “will you also go away?” (John 6:67). Is the holy Eucharist actually a sacrifice? Should we worship the Eucharist?
