He also gave him authority to execute judgment, because he is a son of man.
      I. The doctrine laid down, by which he justified what he did on the sabbath day (John 5:17; John 5:17): He answered them. This supposes that he had something laid to his charge: or what they suggested one to another, when they sought to slay him (John 5:16; John 5:16), he knew, and gave this reply to, My Father worketh hitherto, and I work. At other times, in answer to the like charge, he had pleaded the example of David's eating the show-bread, of the priests' slaying the sacrifices, and of the people's watering their cattle on the sabbath day; but here he goes higher and alleges the example of his Father and his divine authority; waiving all other pleas, he insists upon that which was instar omnium--equivalent to the whole, and abides by it, which he had mentioned, Matthew 12:8. The Son of man is Lord even of the sabbath day; but he here enlarges on it. 1. He pleads that he was the Son of God, plainly intimated in his calling God his Father; and, if so, his holiness was unquestionable and his sovereignty incontestable; and he might make what alterations he pleased of the divine law. Surely they will reverence the Son, the heir of all things. 2. That he was a worker together with God. (1.) My Father worketh hitherto. The example of God's resting on the seventh day from all his work is, in the fourth commandment, made the ground of our observing it as a sabbath or day of rest. Now God rested only from such work as he had done the six days before; otherwise he worketh hitherto, he is every day working, sabbath days and week-days, upholding and governing all the creatures, and concurring by his common providence to all the motions and operations of nature, to his own glory; therefore, when we are appointed to rest on the sabbath day, yet we are not restrained from doing that which has a direct tendency to the glory of God, as the man's carrying his bed had. (2.) I work; not only therefore I may work, like him, in doing good on sabbath days as well as other days, but I also work with him. As God created all things by Christ, so he supports and governs all by him, Hebrews 1:3. This sets what he does above all exception; he that is so great a worker must needs be an uncontrollable governor; he that does all is Lord of all, and therefore Lord of the sabbath, which particular branch of his authority he would now assert, because he was shortly to show it further, in the change of the day from the seventh to the first.
