Prayer History

Listen to Prayer History

This little act of consecration — known from its Latin opening as the O Domina mea — is one of the most widely-prayed of all self-offerings to Our Lady. In a few lines the soul hands itself over to Mary without reserve: eyes, ears, mouth, heart, "my whole being," asking her to keep and guard what is now her own.

By long tradition the prayer is ascribed to St. Aloysius Gonzaga (1568–1591), the young Jesuit and patron of youth, who is said to have prayed it morning and evening. It stands within the wider tradition of Marian consecration — later given its fullest expression by St. Louis de Montfort (1673–1716), who taught that the surest and easiest way to Jesus is through total consecration to Mary, that she might form Christ in the soul. The O Domina mea is a simple daily echo of that same self-gift.

By long custom it is prayed morning and evening, and it was a favorite of many saints as a way of beginning and ending the day in Our Lady's keeping. To consecrate oneself to Mary takes nothing from Christ: because everything she is and has is ordered to her Son, whoever gives himself to the Mother is given all the more surely to God.

💡 Did You Know?

The prayer is called the O Domina mea after its opening Latin words — "O my Lady, O my Mother."
It is traditionally ascribed to St. Aloysius Gonzaga (1568–1591), the young Jesuit patron of youth, who is said to have prayed it every morning and evening.
By custom it is prayed both morning and evening, placing the whole day under Our Lady's protection.
The soul consecrates its senses one by one — eyes, ears, mouth, heart — asking Our Lady to keep and guard him wholly as her own.
Consecration to Mary takes nothing from God: because all she has is ordered to her Son, to give oneself to her is to be given more surely to Christ.
St. Louis de Montfort's fuller method of consecration was later embraced by Pope St. John Paul II, whose motto "Totus Tuus" ("Entirely Yours") is drawn from it.
A daily act like this one is a simple way to live out the total self-gift that the formal 33-day consecration renews.
