Immaculate Heart of Mary School (Massachusetts)

Slaves of the Immaculate Heart of Mary refers to a number of different religious communities which all trace their roots to the St. Benedict Center, founded in 1940 by Catherine Goddard Clarke in Harvard Square, Cambridge, Massachusetts.

In 1945, Leonard Feeney became chaplain of the center. Clarke and Feeney formed the Slaves of the Immaculate Heart of Mary, an independent Catholic community. The group relocated to Still River, a village in the town of Harvard, Massachusetts.

After Clarke's death, around 1968, the group separated into three groups: the St. Benedict Abbey, the Sisters of St. Benedict Center, Slaves of the Immaculate Heart of Mary (Saint Anne's House), and the Slaves of the Immaculate Heart of Mary of Saint Benedict Center. In the mid-1980s, a fourth group split from the latter and founded a separate self-identified Catholic community in New Hampshire.
