At last the cause of her beatification was introduced upon occasion of an appeal addressed to the Holy See, in 1869, by Mgr Dupanloup, Bishop of Orléans, and, after passing through all its stages and being duly confirmed by the necessary miracles, the process ended in the decree being published by Pius X on 11 April, 1909. A Mass and Office of St. Joan, taken from the "Commune Virginum," with "proper" prayers, have been approved by the Holy See for use in the Diocese of Orléans. St. Joan was canonized in 1920 by Pope Benedict XV.Collect:
O God, you have chosen Saint Joan of Arc to defend her country against the invading enemy. Through her intercession, grant that we may work for justice and live in peace. We pray through Jesus Christ, your son, living and reigning with you and the Holy Spirit, one God forever and ever. Amen.
O Lord, on this feast of Saint Joan of Arc, accept this pure offering of the victim who is our salvation. Grant that we may love you in all things and more than all things so that we may live for the praise of your glory. We pray through Christ our Lord. Amen.
You have strengthened us, O Lord, with bread from heaven from which Saint Joan of Arc so frequently found light and comfort. May this heavenly nourishment sustain us in the service of our brothers and sisters. We make our prayer through Christ our Lord. Amen.
