Servant of God Frank Duff is the founder of the Legion of Mary.

God our Father, You inspired your servant Frank Duff with a profound insight into the mystery of Your Church, the Body of Christ, and of the place of Mary the Mother of Jesus in this mystery. In his immense desire to share this insight with others and in filial dependence on Mary he formedher Legion to be a sign of her maternal love for the world and a means of enlisting all her children in the Church’s evangelising work.

We thank you Father for the graces conferred on him and for the benefits accruing to the Church from his courageous and shining faith. With confidence we beg You that through his intercession you grant the petition we lay before You . …………… We ask too that if it be in accordance with Your will, the holiness of his life may be acknowledged by the Church for the glory of your Name, through Christ Our Lord, Amen.
