From Discourses to Mixed Congregations
by Venerable John Henry Newman, C.O.

O my dear brethren, though your conscience witnesses against you, He can disburden it; whether you have sinned less or whether you have sinned more, He can make you as clean in His sight and as acceptable to Him as if you had never gone from Him. Gradually will He destroy your sinful habits, and at once will He restore you to His favour. Such is the power of the Sacrament of Penance, that, be your load of guilt heavier or be it lighter, it removes it, whatever it is. It is as easy to Him to wash out the many sins as the few. Do you recollect in the Old Testament the history of the cure of Naaman the Syrian, by the prophet Eliseus? He had that dreadful, incurable disease called the leprosy, which was a white crust upon the skin, making the whole person hideous, and typifying the hideousness of sin. The prophet bade him bathe in the river Jordan, and the disease disappeared; "his flesh," says the inspired writer, was "restored to him as the flesh of a little child". Here, then, we have a representation not only of what sin is, but of what God's grace is. It can undo the past, it can realise the hopeless. No sinner, ever so odious, but may become a Saint; no Saint, ever so exalted, but has been, or might have been, a sinner.

Also, a thank-you to Zadok for his Oratorian-related posts.
