The finest sermon I have heard since I have been in Paris--and, I am almost inclined to think, the finest I ever heard anywhere--was preached yesterday by the Abbé Deguerry at St. Roch. It was a discourse calculated to benefit all Christian souls of every sect and denomination whatever--had no shade of doctrinal allusion in it of any kind, and was just such a sermon as one could wish every soi-disant infidel might be forced to listen to while the eyes of a Christian congregation were fixed upon him. It would do one good to see such a being cower and shrink, in the midst of his impotent and petulant arrogance, to feel how a "plain word could put him down."
The Abbé Deguerry is a young man, apparently under thirty; but nature seems to have put him at once in possession of a talent which generally requires long years to bring to perfection. He is eloquent in the very best manner; for it is an eloquence intended rather to benefit the hearer than to do honour to the mere human talent of the orator. Beautifully as his periods flowed, I felt certain, as I listened to him, that their harmonious rhythm was the result of no study, but purely the effect, unconsciously displayed, of a fine ear and an almost unbounded command of language. He had studied his matter,--he had studied and deeply weighed his arguments; but, for his style, it was the free gift of Heaven.
Extempore preaching has always appeared to me to be a fearfully presumptuous exercise. Thoughts well digested, expressions carefully chosen, and arguments conscientiously examined, are no more than every congregation has a right to expect from one who addresses them with all the authority of place on subjects of most high importance; and rare indeed is the talent which can produce this without cautious and deliberate study. But in listening to the Abbé Deguerry, I perceived it was possible that a great and peculiar talent, joined to early and constant practice, might enable a man to address his fellow-creatures without presumption even though he had not written his sermon;--yet it is probable that I should be more correct were I to say, without reading it to his congregation, for it is hardly possible to believe that such a composition was actually and altogether extempore.
