The Pharisees were not wrong to love the Sabbath. It was one of God’s great gifts to Israel: a day when no one, not even a slave, had to work. But they had surrounded it with so many rules that it had become a burden. They watched hungry men pick grain and saw only a broken rule.
Jesus reminds them why the day exists. God made it for people: for rest, worship and being together. It was never meant to make life harder for the hungry. And he says he is its lord, which means he decides what it is for.
For Christians, Sunday has become our day of rest and worship. It is easy to let it become either a burden of obligations or just another busy day. Jesus offers a better way: let it be a gift. Come to the Qurbana, rest, eat together, and look out for anyone who is hungry.
