To Rusticus
1. No man is happier than the Christian, for to him is promised the kingdom of heaven. No man struggles harder than he, for he goes daily in danger of his life. No man is stronger, for he overcomes the Devil. No man is weaker, for he is overcome by the flesh. Both pairs of statements can be proved by many examples. For instance, the robber believes upon the cross and immediately hears the assuring words: “verily I say unto you, Today shall you be with me in paradise:” while Judas falls from the pinnacle of the apostolate into the abyss of perdition. Neither the close intercourse of the banquet nor the dipping of the sop nor the Lord's gracious kiss can save him from betraying as man Him whom he had known as the Son of God. Could any one have been viler than the woman of Samaria? Yet not only did she herself believe, and after her six husbands find one Lord, not only did she recognize that Messiah by the well, whom the Jews failed to recognize in the temple; she brought salvation to many and, while the apostles were away buying food, refreshed the Saviour's hunger and relieved His weariness. Was ever man wiser than Solomon? Yet love for women made even him foolish. Salt is good, and every offering must be sprinkled with it. Wherefore also the apostle has given commandment: “let your speech be always with grace, seasoned with salt.” But “if the salt have lost his savour,” it is cast out. And so utterly does it lose its value that it is not even fit for the dunghill, whence believers fetch manure to enrich the barren soil of their souls.
I begin thus, Rusticus my son, to teach you the greatness of your enterprise and the loftiness of your ideal; and to show you that only by trampling under foot youthful lusts can you hope to climb the heights of true maturity. For the path along which you walk is a slippery one and the glory of success is less than the shame of failure.
