We live in confusing times when many are losing their faith. They listen to the world and ask, "Why doesn't the Church change this or that teaching?" Some seem to think that the Church's teachings should be decided by a poll. But the Church is the Body of Christ and it is under authority. It must be obedient to God. It can't make up new teachings or change old ones. If it did, it would lose its authority and become one opinion among many.
Before we receive communion we remember the words of the centurion: "Lord, I am not worthy." We can receive this marvelous gift because the priest has the authority to change ordinary bread into the Blessed Sacrament. He has the authority because the Church has the authority to ordain priests. This authority comes from obedience.
