“While Jesus was going through a field of grain on a sabbath, his disciples were picking the heads of grain, rubbing them in their hands, and eating them. Some Pharisees said, "Why are you doing what is unlawful on the sabbath?" Jesus said to them in reply, "Have you not read what David did when he and those who were with him were hungry? How he went into the house of God, took the bread of offering, which only the priests could lawfully eat, ate of it, and shared it with his companions?" Then he said to them, "The Son of Man is lord of the sabbath." -Luke 6:1-5
Jesus is still Lord of the sabbath and on this sabbath or any other day of the week, inside every Catholic church, Christ makes Himself present in the bread of offering, so He may feed those with Him who are hungry. If you have never experienced the Liturgy of the Word and the Liturgy of the Eucharist, ask a Catholic friend to take you and guide you through the Mass. If you’re Catholic and it has been a while, seek out the sacrament of Reconciliation, and let the Lord of the sabbath once again feed you the Bread of Life.
