Alas! the unregenerate pastor becomes terribly mischievous too, for of all the causes which create infidelity, ungodly ministers must be ranked among the first. I read the other day, that no phase of evil presented so marvellous a power for destruction, as the unconverted minister of a parish, with a 1200-pound (British currency, not weight) organ, a choir of ungodly singers, and aristocratic congregation. It was the opinion of the writer, that there could be no greater instrument for damnation out of help than that. People go to their place of worship and sit down comfortably, and think they must be Christians, when all the time all that their religion consists in, is listening to an orator, having their ears tickles with music, and perhaps their eyes amused with graceful action and fashionable manners; the whole being no better than what they hear and see at the opera—not so good, perhaps, in point of aesthetic beauty, and not an atom more spiritual. Thousands are congratulating themselves, and even blessing God that they are devout worshippers, when at the same time they are living in an unregenerate Christless state, having the form of godliness, but denying the power thereof. He who presides over a system which aims at nothing higher than formalism, is far more a servant of the devil than a minister of God.
