When Christ Offended the Pharisees

Knowest thou that the Pharisees were offended? [Matthew 15:12] As the scribes were presumptuous and rebellious, Christ did not take great pains to pacify them, but satisfied himself with repelling their hypocrisy and pride. The offense which they had formerly taken up was doubled, when they perceived that--not through oversight, but seemingly on purpose--Christ despised their washings as trifles. Now when Christ did not hesitate to inflame still more, by keen provocation, wicked and malicious persons, let us learn from his example, that we ought not to be exceedingly solicitous to please every one by what we say and do. His disciples, however--as is usually the case with ignorant and unlearned people--no sooner perceive the result to be unfavorable, than they conclude that Christ's reply had been unseasonable and improper. For the object   of their advice was, to persuade Christ to soothe the rage of the Pharisees by softening the harsh expression which he had employed.  

It almost always happens with weak persons, that they form an unfavorable judgment about a doctrine, as soon as they find that it is regarded with doubt or meets with opposition. And certainly it were to be wished, that it should give no offense, but receive the calm approbation of all; but, as the minds of many are blinded, and even   their hearts are kindled into rage, by Satan, and as many souls are held under the benumbing influence of brutal stupidity, it is impossible that all should relish the true doctrine of salvation. Above all, we ought not to be surprised to behold the rage of those who inwardly nourish the venom of malice and obstinacy. Yet we ought to take care that, so far as may be in our power, our manner of teaching shall give no offense; but it would be the height of madness to think of exercising greater moderation than we have been taught to do by our heavenly Master. We see how his discourse was made an occasion of offense by wicked and obstinate men; and we see at the same time, how that kind of offense which arose from malignity was treated by him with contempt.

v. 14. Let them alone. He sets them aside as unworthy of notice, and concludes that the offense which they take ought not to give us much uneasiness. Hence has arisen the distinction, of which we hear so much, about avoiding offenses, that we ought to beware of offending the weak, but if any obstinate and malicious person take offense, we ought not to be uneasy; for, if we determined to satisfy all obstinate people, we must bury Christ, who is the stone of offense, (1 Peter 2:8.) Weak persons, who are offended through ignorance, and afterwards return to just views, must be distinguished from haughty and disdainful men who are themselves the authors of offenses. It is of importance to attend to this distinction, in order that no one who is weak may be distressed through our fault. But when wicked men dash themselves through their obstinacy, let us walk on unmoved in the midst of offenses; for he who spares not weak brethren tramples, as it were, under foot those to whom we are commanded to stretch out the hand. It would be idle to attend to others, whom we cannot avoid offending, if we wish to keep the right path; and when, under the pretext of taking offense, they happen to fall off and revolt from Christ, we must let them alone, that they may not drag us along with them.
