It is a commonplace in devotional literature, historical scholarship, and papal writings that Saint Teresa of Avila played a key role in the development of veneration of Saint Joseph. Saint Joseph and the Carmelite Reform of Saint Teresa of Avila unpacks this commonplace by recovering the often-overlooked back story to Teresa's story, namely, the extraordinarily rich liturgical cult of Saint Joseph in the Ancient Order of Carmel which fully flowered in the Teresian Carmel and beyond, to the universal Church.

This volume charts a narrative arc from the liturgical cult of Saint Joseph in the Carmelite Order of Ancient Observance; to Saint Joseph's vital formative presence in Saint Teresa's life and reformed Carmel as father, teacher of prayer, and intercessor in every need; to the Carmelite family as a whole giving liturgical expression to its privileged relationship with Saint Joseph by the establishment of the Feast of the Patronage of Saint Joseph; to this feast becoming widespread outside Carmel and ultimately extended to the Universal Church (1847); and, finally, to Saint Joseph's proclamation as Patron of the Universal Church (1870).

An epilogue considers the absence of Joseph's title "Patron of the Universal Church" in the post-Vatican II liturgical calendar and books, while the papal magisterium has consistently insisted that this patronage is ever necessary for the Church as not only a protection against all dangers, but also an impetus for its mission of evangelization and re-evangelization. An appendix reprints the letter, "Saint Joseph, Patron of Carmel," jointly issued by the Prior General of the Order of Carmelites of the Ancient Observance and the Superior General of the Order of Discalced Carmelites, to mark the 150th anniversary of the proclamation of Saint Joseph as Patron of the Universal Church.
