John Lightfoot on John 16:2

[They shall put you out of the synagogues.] This, I presume, must be understood of a casting out from the whole congregation of Israel, because I know the Jews always proceeded in that manner against the Samaritans; and certainly the disciples of Jesus were full as hateful to them as the Samaritans could be. Nay, they often call the Christians by the name of Cuthites, as well as those.

Those that were cast out of the church they despoiled of all their goods, according to Ezra 10:8: which they also did to those that were shammatized. Whence it may be a question, whether shammatizing did not cast out of the whole congregation; and again, whether one cast out of the whole congregation might be ever readmitted.

We may take notice of what is said in Avodah Zarah. No one that relapseth may be received again for ever. The Gloss tells us that the passage concerns the plebeians or laics, who having taken upon themselves any religious rule of life, go back again from that profession: they do not admit them into that order and society again. Whether therefore those that fell off from the gospel, returning to their Judaism again, were ever admitted into the Jewish church after they had voluntarily forsaken it, might be an inquiry. But these things only by the by.

There was, in truth, a twofold epocha of the persecution of the apostolical church, namely, both before that apostasy of which we have such frequent mention, and also after it. Our Saviour had foretold the apostasy in that tremendous parable about the unclean spirit cast out, and returning again with seven worse. "So shall it be also (saith he) unto this wicked generation," Matthew 12:45. The footsteps of this we may discern almost in every epistle of the apostles.

It is worthy observation, that of 2 Thessalonians 2:3: "The day of the Lord shall not come, except there come a falling away first, and that man of sin be revealed." The day of the Lord here spoken of was that wherein Christ should come and reveal himself in that remarkable vengeance against Jerusalem and the Jewish nation, of which kind of expression we shall say more on chapter 21:22. The 'apostasy' or 'falling away,' and revelation of 'the man of sin,' was to precede that day: which might be easily made out by a history of those times, if I were to do the business either of a historian or a chronologer.

When therefore the severe and cruel persecution was first raised by the unbelieving Jews before this falling away of Christians, it must needs be greatly increased afterward by them and the apostates together: which distinction we may easily observe out of this verse.

[Will think that he doeth God service.] So the zealots, of whom we have mention in Sanhedrim; the zealots kill him. Gloss: "These are those good men who are endued with zeal in the cause of God." Such who with their own hands immediately slew the transgressor, not staying for the judgment of the Sanhedrim. So in the place before quoted, "The priest that ministers at the altar in his uncleanness, they do not bring before the Sanhedrim; but they bring him out into the court, and there brain him with the pieces of wood" provided to maintain the fire upon the altar.

What infinite mischiefs and effusion of blood such pretexts of zeal towards God might occasion, it is easy to imagine, and very direful instances have already witnessed to the world. Hence was it that they so often went about to have stoned our Saviour. Hence those forty and more that had conspired against St. Paul. And those zealots whose butcherly cruelties are so infamous in the Jewish story took the occasion of their horrid madness first from this liberty.

From such kind of villains as these the disciples of Christ could have little safeguard: indeed, they were greatly endangered upon a threefold account: I. From the stroke of excommunication, by which they were spoiled of their goods and estates, Hebrews 10:34. II. From the sentence of the Sanhedrim, dooming them either to be scourged or slain. III. From these assassins; for by this name (a name too well known in Europe) we will call them. We pronounce assassin and assassination; Gul. Tyrius calls them assysins, whom it may be worth the while to consult about the original of that name.
