最も強力な祈りは？ 聖務日課＞聖母の小聖務日課＞ロザリオ

The Officium Parvum Baetae Mariae Virgin (LIttle Office of the Blessed Virgin Mary) is essentially an excerpt from the Divine Office. It is prayed by several traditional orders of sisters and by those who are enrolled in the Confraternity of the Brown Scapular of Our Lady of Mount Carmel.
