To-night, my brethren, a vision meets my eye hardly less beautiful than that which met the eye of the prophet. How beautiful a sight is this church and this congregation! This church is raised to the honor of the true God. Its walls are salvation and its gates praise. And this congregation, beautiful as it is in the assemblage of a multitude of living, intelligent beings--where I see the old man with his crown of silver hair, the young man and the young woman in the freshness of their bloom and youth--is much more so regarded as a Catholic congregation, as professing the true faith. But tell me--for I cannot look into your hearts as the prophet did--tell me, does God see, beneath this beautiful, outward appearance, the abominations of iniquity? Does God this night see in this church some heart that is in mortal sin? Some Catholic who has renounced, if not his faith, at least the practice of his faith? Some child of passion who has swerved from the path of justice, lost his conscience and the sense of sin, and given himself to the service of the devil? Are there any here to-night in mortal sin? There may be. I will confess, and you will not think me uncharitable in doing so, I believe there are some. I know not how many, but from what I know of the world, I believe there are some here, in this congregation, whose consciences tell them they are in mortal sin. Oh! then, let me tell them what they have done. Let me show them what mortal sin is. Let me prove to them that it is an evil and a bitter thing for them to have left the Lord their God. This is my subject to-night. I will show you the dreadfulness of mortal sin: first, from its nature; secondly, from its effects on the soul; and thirdly, from its eternal consequences. {228}
