John Chrysostom

Let us imitate him, since he also was an imitator of Christ. If he, with enemies, who went even to the length of murder and slaughter, said nothing offensive to them, what pardon shall we deserve, who in reviling and abuse become infuriated, calling our enemies villains, detestable wretches? Just as Christ also said: I have not a devil, but I honor My Father: but ye do dishonor Me.

Homily on Acts 50 ↗

Cyril of Alexandria

Gentle is the word, but nevertheless very pointed. For most emphatically does He say, I have not a devil, and putting Himself in contradistinction to them, He shows that He is free from their railing and that it is true of them. For unless themselves had a devil, they would (it is likely) have shuddered at calling Him possessed Who was attested to them by His Deeds as God. Most excellently therefore does He say, I have not, transferring the speech to them and allotting it rather to them by reason that so it was in truth. …

Commentary on the Gospel of John, Book 6 ↗

Theophylact of Ohrid

Thus they insult Him, yet He accepts their insults without malice. However, when they call themselves sons of God, He strongly rebukes them, standing up for the truth; but when He Himself is insulted, He does not defend Himself.

How does He honor the Father? …

Commentary on John ↗

Augustine of Hippo

And to imitate His patience first, if we would attain to His power. But though being reviled, He reviled not again, it was incumbent on Him to deny the charge. Two charges had been made against Him: Thou art a Samaritan, and hast a devil. In reply He does not say, I am not a Samaritan: for Samaritan means keeper; and He knew He was a keeper: He could not redeem us, without at the same time preserving us. Lastly, He is the Samaritan, who went up to the wounded, and had compassion on him. (Tr. xliii. …

Catena Aurea by Aquinas ↗

Gregory the Dialogist

See; when God suffers a wrong, He does not reply reproachfully: Jesus answered, I have not a devil. An intimation this to us, that when reproached by our neighbours falsely, we should not retort upon them by bringing forward their evil deeds, however true such charges might be; lest the vehicle of a just rebuke turn into a weapon of rage. (Hom. xliii. …

Catena Aurea by Aquinas ↗

Thomas Aquinas

Then when he says, Jesus answered: I have not a demon, our Lord rejects the response of the Jews. Now they had taxed Christ with two things, that he was a Samaritan and that he had a demon. Concerning the first, our Lord makes no apology, and this for two reasons. First, according to Origen, because the Jews always wanted to keep themselves apart from the Gentiles. But the time had now come when the distinction between Jews and Gentiles was to be removed, and everyone was to be called to the way of salvation. …
