Father Brisson, a zealous apostle opened in 1858, a Centre where he would welcome young girls working in the mils. He decided, under the inspiration of God to establish a religious congregation to direct this important work. In Leonie Aviat he founded an incomparable co-worker and a zealous apostle, like himself. This young lady who had earlier and attraction towards the contemplative life of the Visitation Order, was affected by the plight of young factory workers and felt herself called to the attractive apostolate. Thus the congregation of the Oblate sisters came to be found. Placed under the patronage of St. Francis de Sales, the congregation completely identified with the Spiritual and identity of the Bishop.
For many years Mother Mary de Sales Chappuis, of the Visitation Sisters in Troyes, had been encouraging the Chaplin to start a Congregation of priest following the spirit and teaching of St. Francis de Sales. After some years, in 1876 he founded the Oblates of St. Francis de Sales (priest's and brothers). When the Vicar Apostolic of the Cape of Good hope, Bishop John Leonard, heard that the Society of African Missions of Lyons had decided to recall its subject from the Namaqualand and the North-Western Cape, he made a trip to Europe in 1880 in hope of finding a Congregation willing to assume the responsibility of evangelizing these areas. In 1882 Fr. Brisson sent the first missionaries to South Africa: Fr Jean Marie Simon, Fr. Jouax and Br. Giraud. They arrived in Pella on the 2 September 1882. Other missions were established afterwards: Matjieskloof 1885, Nababeep 1900 and Port Nolloth in 1904. In Namibie missions were founded: Heirachabis in 1896, Warmbad in 1907 and Gabis in 1907.
Today the Oblates are located throughout the world, in Holland, Germany, Austria, France, Switzerland, Italy, India, South Africa, Namibia, Benin, Ivory Coast, Uruguay, Brazil, Ecuador, Mexico, Haiti and the United States. They continue their mission of spreading the spiritual tradition of St. Francis de Sales a diverse congregation. Oblates live in common life, supporting one another to live authentic lives of faith. They profess the vows of Poverty, Chastity and Obedience. They are men and women of prayer, centered on Jesus and the imitation of his love of God and all humanity. Oblates of St. Francis de Sales live and spread Salesian Spirituality: humility, gentleness, optimism and above all the practice of little virtues.
