Matthew 19:3

Seeing the Lord thus tempted, let none of His disciples who is set to teach think it hard if he also be by some tempted. Howbeit, He replies to His tempters with the doctrines of piety.

But not so to the Pharisees, but even for this self-same thing they become more fierce, and come unto Him tempting Him. For because they could not lay hold of the works that were doing, they propose to Him questions. O folly! They thought to silence Him by their questions, although they had already received certain proof of this power in Him. When at least they argued much about the Sabbath, when they said, "He blasphemeth," when they said, "He hath a devil," when they found fault with His disciples as they were walking in the corn fields, when they argued about unwashen hands, on every occasion having sewed fast their mouths, and shut up their shameless tongue, He thus sent them away. Nevertheless, not even so do they keep off from Him. For such is wickedness, such is envy, shameless and bold; though it be put to silence ten thousand times, ten thousand times doth it assault again. But mark thou, I pray thee, their craft also from the form of their question. For neither did they say unto Him, Thou didst command not to put away a wife, for indeed He had already discoursed about this law; but nevertheless they made no mention of those words; but took occasion from hence, and thinking to make their snare the greater, and being minded to drive Him to a necessity of contradicting the law, they say not, why didst Thou enact this or that? but as though nothing had been said, they ask, "Is it lawful?" expecting that He had forgotten having said it; and being ready if on the one hand He said, "It is lawful to put away," to bring against Him the things He Himself had spoken, and to say, How then didst Thou affirm the contrary? but if the same things now again as before, to bring against Him the words of Moses. What then said He? He said not, "tempt ye me, ye hypocrites?" although afterwards He saith this, but here He speaks not thus. Why can this be? In order that together with His power He might show forth His gentleness also. For He doth neither always keep silence, lest they should suppose they are hidden; nor doth He always reprove, in order that He may instruct us to bear all things with gentleness.

That they might have Him as it were between the horns of a syllogism, so that, whatever answer He should make, it would lie open to cavil. Should He allow a wife to be put away for any cause, and the marriage of another, he would seem to contradict Himself as a preacher of chastity. Should He answer that she may not be put away for any cause whatsoever, He will be judged to have spoken impiously, and to make against the teaching of Moses and of God.

But, as when you see one much pursuing the acquaintance of physicians, you know that he is sick, so, when you see either man or woman enquiring concerning divorce, know that that man is lustful and that woman unchaste. For chastity has pleasure in wedlock, but desire is tormented as though under a slavish bondage therein. And knowing that they had no sufficient cause to allege for their putting away their wives, save their own lewdness, they feigned many divers causes. They feared to ask Him for what cause, lest they should be tied down within the limits of fixed and certain causes; and therefore they asked if it were lawful for every cause; for they knew that appetite knows no limits, and cannot hold itself within the bounds of one marriage, but the more it is indulged the more it is kindled.
