Roman Relations with: The Oblate Sisters of Providence (OSP) is a Catholic women's religious institute founded by Mother Mary Elizabeth Lange, and Father James Nicholas Joubert in 1829 in Baltimore, Maryland for the education of girls of African descent.

The Oblate Sisters were free women of color who served to provide Baltimore's African-American population with education and "a corps of teachers from its own ranks.

After his ordination, Father Joubert was given charge of the black French-speaking Catholics of St. Mary's chapel, who were primarily also from Saint-Domingue.

A little over a year later, on 2 July 1829, the first four sisters, Mary Elizabeth Lange from Santiago, Cuba (she was born in Saint-Domingue); Mary Rosine Boegues of Saint Domingue (Haiti); Magdelaine Frances Balas of Saint Domingue (Haiti); and Theresa Maxis Duchemin of Baltimore, made their vows.

The OSPs established seven missions in Cuba but left in 1961 when the regime of Fidel Castro made it impossible for them to continue their work.

By 1910 the sisters conducted schools and orphanages at Baltimore, Washington state, Leavenworth, Kansas, and St. Louis and Normandy, Missouri.

[8] The Cosbys made another donation in 2012 to assist St. Frances Academy in building a community center in East Baltimore.

[10] "The original inspiration of the Oblate Sisters of Providence is that gift of the Spirit so evident in the life of Mother Mary Lange.

This charism enables us, with total trust in God's Providence, to bring joy, healing and the liberating, redemptive love of the suffering Jesus to the victims of poverty, racism, and injustice despite contradictions, prejudice and pain.

The Oblate Sisters continue in Baltimore, Maryland; Miami, Florida; Buffalo, New York; and Alajuela and Siquirres, Costa Rica.

The motherhouse contains the administrative offices, a health care unit, a novitiate (there is also a novitiate in Costa Rica), the Mother Lange Guild (supporting the cause for canonization of Mother Lange), and the Oblate Sisters of Providence Archives and Special Collections Library.
