Matthew 12:11

11.What man shall there be among you who shall have a sheep? Christ again points out what is the true way of keeping the Sabbath; and, at the same time, reproves them for slander, in bringing as a charge against him what was a universal custom. For if any man’s sheep had fallen into a ditch, no person would have hindered it from being taken out: but in proportion as a man is of more value than a sheep, so much the more are we at liberty to assist him. It is plain, therefore, that if any man should relieve the necessity of brethren, he did not, in any degree, violate the rest which the Lord has enjoined. Mark and Luke take no notice of this comparison, but only state that Christ inquired, Is it lawful on the Sabbath to do good or to do evil?

He who takes away the life of a man is held to be a criminal; and there is little difference between manslaughter and the conduct of him who does not concern himself about relieving a person in distress. So then Christ indirectly charges them with endeavoring, under the pretense of a holy act, to compel him to do evil; for sin is committed, as we have already said, not only by him who does any thing contrary to the Law, but also by him who neglects his duty. Hence also we perceive, that Christ did not always employ the same arguments in refuting this slander; for he does not reason here about his divinity as he does in the case mentioned by John, (John 5:18.) Nor was there any necessity for doing so; since the Pharisees were completely refuted by this single defense, that nothing could be more unreasonable than to pronounce a man, who imitated God, to be a transgressor of the Sabbath.
