LYONNARD, Jean. - Jesuit, writer on ascetics, b. at Remoulin (diocese of Nîmes) on 27 Dec. 1819, d. at Vals (Le Puy) on 9 Jan. 1887.
He adopted as a particular form of his asceticism and as the aim of his ministries the apostolate through the sanctification of suffering, especially on behalf of the dying. For this reason he promoted the Archconfraternities of the Agonizing Heart and, in order to exercise a more regular and continuous action, he founded with the cooperation of Madame Tradadoux the Institute of the Religious of the Agonizing Heart (1859) and propagated his idea through his writings.
Besides the numerous articles he composed for the *Messager du Sacré-Cœur de Jésus*, he wrote his principal work, often republished and translated: *L’apostolat de la souffrance* (Paris 1865, Italian ed. Turin 1942), preceded and followed by others: *Devotion au Cœur agonisant de Jésus* (Avignon 1850); *Devotion au Cœur compatissant de Marie* (ibid. 1850); *Le Cœur agonisant de Jésus et les agonisants de chaque jour* (Paris 1852); *L’intercession perpétuelle au Cœur compatissant de Marie pour les quatre-vingt-mille agonisants, qui meurent, chaque jour* (ibid. 1867); *L’œuvre du salut des mourants* (Le Puy 1883).
