For the Son of man is Lord even of the sabbath day.
All Commentaries on Matthew 12:8 Go To Matthew 12

You will also thus observe that knowing God is more necessary than resting on the sabbath. The sabbath was given to the Jews when, in Egypt, they were turned toward idolatry. And the sabbath was given for this reason: so that they would not call the world uncreated and outside the sphere of providence, but that they would acknowledge that God is both the One who planned it and that it is he himself who made the world in six days and on the seventh day rested. When God commanded them to do no work on the sabbath, it was to remind them of this. Subsequently, the fact that God is the Maker of the universe has become known to all, and so much of the detailed sabbath law has become superficial. If these extreme arguments about the sabbath were truly useful, they would have been applied not only to human beings but even to the sun and moon. Imagine that the very sun would cease working its benefits to us on the sabbath day. No. This commandment has been given to human beings, even from the foundation of the world.
