Matthew Poole and continuators on John 2:18

18 ¶ Then answered the Jews , and said unto him , What sign shewest thou unto us, seeing that thou doest these things l?

Which of the Iews, whether some of the Magistrates, or the Priests, (who were more specially concerned for their profit) or the common people, or all together, is not said. They undertake not to justifie their fact, nor could they deny it, but they ask him what sign he could shew them, to justifie his Divine Authority. For this seemeth to have been their principle, That let Corruptions and Abuses in a Church be never so great, yet they were not to be reformed, but either by the ordinary Authority of the Magistrate, or by an extraordinary Authority from God. Such an extraordinary Authority they would acknowledg in Prophets, but they expected that those who pretented to such an extraordinary Divine Mission, should be able to confirm that Mission by some miraculous Operations, (as Moses did, Exod. 4.30.) They had had no Prophets now for 400 years amongst them; the Iews required therefore a sign, 1 Cor. 1.22 The Papists were at the same point with the first Reformers; but they mistook; for they brought no new Doctrine; but still cried, to the Law, and to the Testimony; and where the true Doctrine and Sacraments are upheld, there is a true Church, which hath power to call and send out Preachers.
