|You Are the Chosen One|
O Mary, of All Women was written by Sulpician Priest, Fr. Michael Gannon. It was first published in 1966 as part of the Peoples Mass Book, one of the earliest english-language hymnals to correspond to the liturgical reforms of Vatican II. Fr. Gannon studied at The Catholic University of America and at the Louvain from 1957 to 1958. O Mary, of All Women is set to the 17th century Flemish tune, Au Fort de ma Detresse. An alternative tune that can also be used is Aurelia, as featured in the following video. It is used in the Liturgy of the Hours on the Feast of Mary, Mother of God.
