The Abbé Coudrin gathered by degrees a number of young persons round him, and succeeded in setting his Congregation on foot, which was recognised in 1817 by Pius VII. In the year 1837 he died, having witnessed many establishments of his Congregation in France; the foundation of one at Valparaiso: many of his disciples evangelising the Polynesian islands, and two of his children bishops, M. Bonamie, first Bishop of Babylon, and then Archbishop of Smyrna, and M. Rouchouze, Vicar Apostolic of Eastern Oceania. On his death the former was chosen for the government of the Congregation by its general chapter.
At present the Congregation has, besides twenty-four establishments in France, two houses in Chili, and two in Belgium; one at Louvain, the other at Enghien, for instruction of youth. It has about one hundred missionaries, priests and catechists, in the Sandwich Islands, the Marquesas, Oceania, and elsewhere.
The object of the institution is to retrace the four periods of our Lord's life: His infancy, His hidden life, His evangelical life, and His crucified life.
With respect to our Lord's infancy, gratuitous schools are kept for poor children; and larger schools, to which a certain number of young persons is admitted free of charge, according to the resources of each establishment. Those intended for the Church are here prepared for their sacred functions.
As to our Lord's hidden life, all members of the Congregation are to imitate it by repairing in the perpetual adoration, day and night, of the Most Holy Sacrament, the wrongs done to the Sacred Hearts of Jesus and of Mary, by the sins which are committed.
Priests imitate our Lord's evangelic life by the preaching of the Gospel, and by missions.
Lastly, all members of the Congregation should recall, so far as in them lies, our Saviour's crucified life, by practising with zeal and prudence works of Christian mortification, specially in the mastery of their senses.
In 1833 Gregory XVI. entrusted to the Society of Picpus the missions of Eastern Oceania.
There are houses for the novitiate at Issy, near Paris, at Louvain, and at Graves, near Villefranche. It continues not more than eighteen, nor less than twelve months. Here are priests and candidates for the priesthood, preparing themselves to live under the laws of religious obedience, and to devote themselves either to the instruction of youths, or to missions, or to the direction of souls, in the post assigned to them by their obedience; or to deeper studies, which shall enable them to serve the faith according to the talents God has given them.
Young men and adults likewise are received, who, without being called to the ecclesiastical state, wish to consecrate themselves to God for the advancement of His glory, and the assuring of their own salvation by the practice of religious virtues.
