In the sense of “4. malign, vilify, revile.” He exposed the false teachers, false prophets, and money changers using whips and strong words. So did the Apostle Paul, Jude, Peter, and others.
Now this raises an interesting question, for which I think I know the answer, but could be persuaded otherwise.
Jesus never speaks harshly to sinners, to those who are outside the religious realm. He only speaks harshly to hypocrites and heretics within the religious realm: to the Sadducees concerning the resurrection, to the Pharisees concerning their hypocrisy, to the moneychangers concerning their misuse of religion for personal gain.
This teaches me how to relate to others within a presumably Christian society. If I am talking to someone outside the church, I present the gospel without condemnation; if I am talking to someone inside the church, particularly those in authority, I speak truth to power. When I talk with the co-worker who laughs at Christianity, I simply present the gospel in word and deed. When I talk to those within the church who desecrate the gospel by, among other things, promoting abortion, or homosexuality, or money-grubbing, or socialism, who deny the deity of Christ or His saving power, then I do not mince words, any more than Christ minced words in Matthew 23, or Paul when he said that the circumcisers should go all the way and emasculate themselves.
So when Christians deal with Islam, which is it? Do we present the gospel without condemnation, or do we refuse to mince words? I think the answer is this. As individual Christians, we present the gospel with kindness to individual Muslims--not the jihadists with guns drawn, mind you, the individual Muslim co-worker or neighbor, just as one would with any other individual co-worker or neighbor. As the church, however, we should brand Islam for what it is, a hypocritical heresy that proclaims peace but makes war, proclaims equality but establishes dhimmitude, that proclaims respect for the peoples of the Book but aims for annihilation of all Jews and believing Christians, and most importantly proclaims Jesus as a "prophet" but refuses to worship Him as God the Son. Every Christian, from Pope Francis and the Metropolitans and the Protestant denominational leaders to the most minor layperson everywhere, should excoriate Islam and those who lead it, not primarily for jihad--though jihad deserves to be excoriated in the strongest of terms and strongest of actions as well--but even if there were never to be a jihadist attack again, because of heresy--because all who proclaim Jesus as anything less than God the Son have denigrated Him, and put something else in His place, as did the Pharisees who worshipped the Law instead of the God who gave the Law, as the moneychangers who worshipped mammon instead of the God who gave the mammon.
Let's stop trying to play games. The disease of Islam isn't jihad; the disease of Islam is Islam, and jihad is simply a symptom that wracks the world in pain and suffering. Speak the truth--for Jesus is the way, the truth, and the life, and no one comes to the Father but through Him.
