Matthew 11:6

This saying, that they were blessed from whom there should be no offence in Him, showed them what it was that John had provided against in sending them. For John, through fear of this very thing, had sent his disciples that they might hear Christ.

And blessed is he who shall not be offended in me, is directed against the messengers; they were offended in Him. But He not publishing their doubts, and leaving it to their conscience alone, thus privately introduced a refutation of them.

(Hom. in Ev. vi. 1.) Otherwise; The mind of unbelievers was greatly offended concerning Christ, because after many miracles done, they saw Him at length put to death; whence Paul speaks, We preach Christ crucified, to the Jews a stumbling-block. (1 Cor. 1:23.) What then does that mean, Blessed is he who shall not be offended in me, but a direct allusion to the humiliation of His death; as much as to say, I do indeed wonderful works, but do not disdain to suffer humble things. Because then I follow you in death, men must be careful not to despise in Me My death, while they reverence My wonderful works.

Knowing therefore, as being God, the mind with which John had sent them, He straightway cured blind, lame, and many others; not to teach him (for how should He him that was convinced), but these that were doubting: and having healed them, He saith, "Go and show John again those things which ye do hear and see; the blind receive their sight, and the lame walk, and the lepers are cleansed, and the deaf hear, and the dead are raised up, and the poor have the gospel preached unto them." And he added, "And blessed is he, whosoever shall not be offended in me;" implying that He knows even their unuttered thoughts. For if He had said, "I am He," both this would have offended them, as I have already said; and they would have thought, even if they had not spoken, much as the Jews said to Him, "Thou bearest record of Thyself." Wherefore He saith not this Himself, but leaves them to learn all from the miracles, freeing what He taught from suspicion, and making it plainer. Wherefore also He covertly added His reproof of them. That is, because they were "offended in Him," He by setting forth their case and leaving it to their own conscience alone, and by calling no witness of this His accusation, but only themselves that knew it all, did thus also draw them the more unto Himself, in saying, "Blessed is he, whosoever shall not be offended in me." For indeed His secret meaning was of them when He said this.
