In his apostolic letter Patris Corde ("With a Father's Heart"), Pope Francis reflects on Saint Joseph and his multifaceted role as a father. The purpose of this letter, Pope Francis writes, "is to increase our love for this great saint, to encourage us to implore his intercession and to imitate his virtues and his zeal." Saint Joseph is a beloved father; a tender, loving father; an obedient father; an accepting father; a creatively courageous father; a working father; and a father in the shadows. As protector, advocate, and guardian of the Holy Family, Saint Joseph has always been venerated as a father to all Christians.

With this letter, promulgated on the 150th anniversary of the declaration of Saint Joseph as Patron of the Universal Church, Pope Francis proclaimed a Year of Saint Joseph from December 8, 2020, to December 8, 2021.

Patris Corde ends with a new prayer to Saint Joseph, and the OSV edition includes additional prayers and a litany to this beloved saint.
