The fiery zealot
There are many other enthusiasts of this sort. Such, for instance, is the fiery zealot for religion — or (more probably) for the opinions and modes of worship which he dignifies with that name. This man also strongly imagines himself to be a believer in Jesus, yes, that he is a champion for the faith which was once delivered to the saints (Jude 3). Accordingly all his conduct is formed upon that vain imagination. And allowing his supposition to be just, he would have some tolerable plea for his behavior; whereas now it is evidently the effect of a distempered brain as well as of a distempered heart.
