John Calvin on Acts 21:28-29

28. Men of Israel, help. They cry out as if they were in extreme danger, and they call upon all men to help them, as if all religion were in hazard. Whereby we see with what furious hatred they were inflamed against Paul, only because in showing that the full and perfect truth is found in Christ, he taught that the figures of the law had an end. Now, whereas they conceive a false opinion, having seen Trophimus, they do more betray by this headlong lightness how venomous they be. They accuse Paul of sacrilege. Why? because he brought into the temple a man which was uncircumcised. But they laid a most cruel “Atrocissimum,” most atrocious. crime to the charge of an innocent through a false opinion. Thus the boldness of those men useth commonly to be preposterous who are carried away with an opinion conceived before. But let us learn by such examples to beware of the distemperature of affections, and not to let light prejudices have the rein, lest we run headlong upon the innocent, being carried with blind force.
