Before the civil wars, even those who most disliked the opinions and manners of the Puritan were forced to admit that his moral conduct was generally, in essentials, blameless; but this praise was now no longer bestowed, and, unfortunately, was no longer deserved. The general fate of sects is to obtain a high reputation for sanctity while they are oppressed, and to lose it as soon as they become powerful: and the reason is obvious. It is seldom that a man enrolls himself in a proscribed body from any but conscientious motives. Such a body, therefore, is composed, with scarcely an exception, of sincere persons. The most rigid discipline that can be enforced within a religious society is a very feeble instrument of purification, when compared with a little sharp persecution from without. We may be certain that very few persons, not seriously impressed by religious convictions, applied for baptism while Diocletian was vexing the Church, or joined themselves to Protestant congregations at the risk of being burned by Bonner. But, when a sect becomes powerful, when its favour is the road to riches and dignities, worldly and ambitious men crowd into it, talk its language, conform strictly to its ritual, mimic its peculiarities, and frequently go beyond its honest members in all the outward indications of zeal. No discernment, no watchfulness, on the part of ecclesiastical rulers, can prevent the intrusion of such false brethren. The tares and wheat must grow together. Soon the world begins to find out that the godly are not better than other men, and argues, with some justice, that, if not better, they must be much worse. In no long time all those signs which were formerly regarded as characteristic of a saint are regarded as characteristic of a knave.
