Pope Francis includes this prayer to Saint Joseph in the apostolic letter:
Hail, Guardian of the Redeemer,
Spouse of the Blessed Virgin Mary.
To you God entrusted his only Son;
in you Mary placed her trust;
with you Christ became man.
Blessed Joseph, to us too,
show yourself a father
and guide us in the path of life.
Obtain for us grace, mercy and courage,
and defend us from every evil. Amen.
