There is much wisdom in thus giving to music an important part in the public ceremonies of religion. Nothing commands and enchains the attention with equal power: the ear may be deaf to eloquence, and the thoughts may often grovel earthward, despite all the efforts of the preacher to lead them up to heaven; but few will find it possible to escape from the effect of music; and when it is of such a character as that performed in the Roman Catholic church on Good-Friday, it can hardly be that the most volatile and indifferent listener should depart unmoved. This service was advertised as "The Three Hours' Agony." The crowd assembled to listen to it was immense. It is impossible to speak too highly of the composition of the music; it is conceived in the very highest tone of sublimity; and the deeply effective manner of its performance recalled to me an anecdote I have heard of some young organist, who, having accompanied an anthem in a manner which appeared greatly superior to that of the usual performer, was asked if he had not made some alteration in the composition. "No," he replied, "I have not; but I always read the words when I play." So, I should think, did those who performed the services at St. Roch on Good-Friday; and nothing can be imagined more touching and effective than the manner in which the whole of these striking ceremonies were performed and arranged there. The awful gospel of the day furnished a theme for the impassioned eloquence of several successive preachers; one or two of whom were wonderfully powerful in their manner of recounting the dreadful narrative. They were all quite young men; but they went through the whole of the appalling history with such deep solemnity, such strength of imagery and vehemence of eloquence, as to produce prodigious effect. At intervals, while the exhausted preachers reposed, the organ, with many stringed instruments, and a choir of exquisite voices, performed the same gospel, in a manner that made one's whole soul thrill and quiver within one. The suffering--the submission--the plaintive yet sublime "It is finished!" and the convulsive burst of indignant nature that followed, showing itself in thunder, hail, and earthquake, were all brought before the mind with most miraculous power. I have been told since, that the services at Notre Dame on that day were finer still; but I really find some difficulty in believing that this is possible.
