Why do Catholics pray the Hail Mary?

Catholics pray the Hail Mary because its words come from Scripture itself—the angel Gabriel's greeting and Elizabeth's blessing at the Visitation—joined to a humble petition asking Mary, the Mother of God, to intercede for us now and at the hour of our death.

Catholics pray the Hail Mary because it is one of the oldest and most Scriptural prayers in the Church, drawing directly on the words the Holy Spirit inspired at the Annunciation and the Visitation. Far from being an invention added onto the Gospel, its first half is the Gospel itself, spoken back to God in praise of what He accomplished in Mary.

The prayer's second half is a simple plea for intercession: 'Pray for us sinners, now and at the hour of our death.' Catholics ask Mary to pray for them because she is the Mother of the Church and the most powerful intercessor among the saints, who now shares fully in the life of her Son in heaven.

The Scriptural Roots of the Prayer

The first line comes from the Archangel Gabriel's greeting: 'Hail, full of grace, the Lord is with thee: blessed art thou among women' (Luke 1:28). The second phrase is drawn from Elizabeth's Spirit-filled exclamation when Mary visited her: 'Blessed art thou among women, and blessed is the fruit of thy womb' (Luke 1:42). When Catholics pray the Hail Mary, they are literally repeating inspired Scripture, echoing heaven's own greeting to the Mother of God.

The title 'Mother of God' reflects the Church's confession that Mary bore in her womb the Son who is truly God and truly man (CCC 495). Because Elizabeth, filled with the Holy Spirit, called Mary 'the mother of my Lord' (Luke 1:43), the Church has always honored Mary with the same reverence given by Scripture itself.

Why Ask Mary to Pray for Us?

Asking Mary's intercession does not compete with Christ's unique mediation; rather, her prayer draws its whole power from union with Him (CCC 2673-2679). Just as we ask fellow believers on earth to pray for us, Catholics ask Mary and the saints in heaven, who are alive in Christ and see God face to face, to intercede for us before the throne of grace (CCC 956, 2683).

Mary's own words at Cana, 'Do whatsoever he shall tell you' (John 2:5), show her constant role of leading souls to her Son. The Hail Mary asks her to do this very thing for us today, and again at the final and most decisive moment, the hour of our death.

A Prayer of Praise and Trust

The Church teaches that the Hail Mary is at once a joyful blessing of Mary for the graces given her and a confident request that she stand with us in life's greatest need (CCC 2676-2677). It is fitting that Catholics repeat this prayer often, especially in the Rosary, since it unites the believer's voice with the very words of the angel and of Elizabeth, keeping the Incarnation ever fresh in the heart.
