The BG Difference


Partners in Mission


In post-revolutionary France, Father André Coindre, filled with compassion for the suffering of young people, established a religious institute of consecrated men, the Brothers of the Sacred Heart, to serve them. Coindre’s simple progression from viewing with open eyes the suffering of young people, to experiencing deep, heart-felt compassion for them, and then acting to alleviate that suffering came to be recognized by the Church as a “charism,” a gift given by the Holy Spirit to an individual for the good of the entire Church. Today, Coindre’s charism thrives not only at Bishop Guertin but in all 11 of the Province of the United States schools of the Brothers of the Sacred Heart. As genuine partners in mission, the Brothers and lay men and women who work in these schools strive to embody Coindre’s charism through word and through deed.
