Sisters Slaves of the Immaculate Heart of Maryof Saint Benedict Center • Harvard, Massachusetts
Brides of Christ
The Sisters MICM take vows as Brides of Christ and live a traditional active religious life of prayer and work nourished by the Traditional Latin Liturgy and dedicated to Jesus through Mary.
The Slaves of the Immaculate Heart of Mary of Saint Benedict Center is a traditional, active Order founded by Fr. Leonard Feeney and re-founded by Brother Hugh MacIsaac in 1976.
The community lives the spirit of True Devotion to Mary as described in the treatise written by Saint Louis Marie de Montfort. Consecrating themselves to Our Lady, they give her everything even the merits of all their actions without exception.
Our monastery, named after Saint Benedict, reflects our life of work and prayer. We are a Public Association of the Faithful in the Diocese of Worcester, Massachusetts.
Traditional Liturgy
The Slaves of the Immaculate Heart of Mary have an unbroken history of Tridentine Liturgy, on which their prayer life is based.
Active Religious Life
Our commitment to Total Consecration enables us to embrace many apostolates to reach souls and bring them to Jesus through Mary.
Living True Devotion
The title, the Slaves of the Immaculate Heart of Mary, taken from the writings of Saint Louis Marie de Montfort, is both bold and beautiful. It captures the complete consecration of the only religious community that has dared to use this title and to glory in its lowliness.
