Reparation is a work destined to save society. ~Pope Pius IX A layman of extraordinary sanctity... The admirers of our holy friend will find him portrayed with his noble and calm physiognomy, the heroic perfection of his virtues, the charming traits of his character, his exuberant piety. He is always the man of God, the "just" living the "life of faith" and prayer. But he is particularly and above all, the man of reparation, the adorer of the Holy Face. This controlling feature is presented entire, and with the prominence it deserves. The work of reparation, such as the social wounds of our age demand, and such as Mr. Dupont inaugurated in his parlor, is exhibited in its origin, development, and early results, with its expressive emblem, and the efficacious means our Lord Himself deigns to offer: adoration of the Holy Face. From the example of this worthy servant of Christ and the Church, we hope the reader may be induced to follow the providential impulse which is, at the present time, so strongly urging generous souls to works of reparation, and which seems to be the pledge of the Divine mercy, the harbinger of a brighter future. We dedicate this volume to the friends of Mr. Dupont and to all the servants of the Holy Face. By their aid and under their auspices, may it be circulated, read, and attain the end for which it was written-the glory of God and the salvation of souls! ~The author, Fr. Pierre Désiré Janvier (M. l'Abbé Janvier)
