Early in the eighteenth century, Catholic missionaries evangelized Choctaw, Chinchuba, and other Indian tribes and sub-tribes on the northern shore of Lake Pontchartrain. Among the pioneer priests was Fr. Michael Baudouin, S.J., superior of the Jesuit Mission in Louisiana and Vicar General to the Bishop of Quebec, Canada. Fr. J. Outendrick was the first resident pastor when the Mandeville congregation was organized in 1850. Fr. Adrien E. Rouquette, "Chahta-Ima," also labored here and elsewhere in St. Tammany Civil Parish. The present church was dedicated in 1953 during the pastorate of Fr. Canisius Bluemel, O.S.B., one of several Benedictines serving here since 1890.
