                               The faithful who devoutly visit an image of the Virgin Mother of God of "Guadalupe," exposed in some church or public oratory,
                                on any of the five Sundays immediately preceding the feast of the Apparation of Our Lady of Guadalupe may gain:
                                 A plenary indulgence, if they make their confession, receive Holy Communion and pray for the intentions of Holy Mother the Church.
 


Also from the Raccolta- A prayer to Our Lady of Guadalupe                                       Our Lady of Guadalupe, mystical rose, make intercession for Holy Church, help all those who invoke thee in their necessities, and since thou art the ever Virgin Mary and Mother of the true God, obtain for us from thy most Holy Son the grace of keeping our faith, sweet hope in the midst of the bitterness of life, burning charity and the precious gift of final perseverance.  Amen.
   An indulgence of 500 days.
