Our Lady of Guadalupe,
make intercession for the holy Church,
protect the Sovereign Pontiff,
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,
and the precious gift of final perseverance.
