Thus here also they prove themselves liars, proud men, and revilers. Since they are accustomed to fight against God, they will receive fitting punishment from the Almighty Judge.
Here again we must seek the reason why they call the Lord a Samaritan and possessed by a demon. Their preceding words, "Do we not say well?" show that for certain reasons they both revile Him as a Samaritan and dare to give Him another name.
They call Him a Samaritan because He seemed indifferent to the commandments of the Law and counted the breaking of the Sabbath as nothing. For the Judaism of the Samaritans was incomplete. Their worship was a kind of mixture with foreign and Hellenic customs.
Or they call Him a Samaritan for another reason. The Samaritans were accustomed falsely to boast of their purity and to condemn others as defiled. On this pretext, I think, "the Jews have no dealings with Samaritans," as it is written (Jn 4:9).
They also refuse communion with certain others, turning away, as they suppose, from the defilement that would follow. This chatter appears to them to be just.
The Lord, condemning the evil character of the Jews, called them sons of the devil. He declared Himself free from sin, bearing witness to His complete purity in the words, "Which of you convicts Me of sin?" (Jn 8:46).
In these words He most plainly ascribes to Himself perfect purity, because He cannot fall under sin. By calling the Jews children of Satan, He condemns them as defiled and as having a mind filled with every uncleanness, which is true.
For this reason they call Him a Samaritan. They also revile Him as possessed, because demons are accustomed to claim for themselves the honor due to God. They shamelessly steal the glory of God.
In their opinion, this is precisely what Christ does when, being man, He places Himself in the position of God. He says, "He who is of God hears the words of God" (Jn 8:47). In this way He shows that these words of God are also His own words.
Such was the pretext by which the Jews blamed Him, or rather blasphemed Him. Moved by this, they spoke the words cited above to Him. By this they secured eternal fire for themselves.
Here again I must wonder at them. They are angry because they have often been called sons of the devil and liars. Yet by their deeds they show that this charge is present in them. On the contrary, they ought to have turned the accusation aside by striving for virtue.
Love of reviling, and calling something present in a man when it is not present, is certainly not proper to those numbered among God's children. It belongs to the sons of the devil.
But these wretched men not only revile, uttering falsehood against their own heads, not to say against Christ. They also insist that they do this "well," being in no way conscious of their wickedness. This is proof of extreme blindness.
