Servant of God Luis María Martínez (1881–1956) was a distinguished Mexican archbishop, theologian, philosopher, and poet, renowned for his deep spirituality and leadership during a tumultuous period for the Catholic Church in Mexico. Born in Michoacán, he was ordained a priest in 1904 and consecrated as an auxiliary bishop in 1923. In 1937, he became the Archbishop of Mexico City, a position he held until his death. His tenure coincided with the Cristero War, a time of severe religious persecution, during which he provided pastoral care and guidance to his flock.

Archbishop Martínez was a prolific writer, contributing significantly to Catholic spiritual literature. His works, such as "The Sanctifier" and "Only Jesus," delve into themes of holiness, the workings of the Holy Spirit, and the interior life, reflecting his profound understanding of Christian spirituality. His writings continue to inspire and guide the faithful, emphasizing the importance of a deep, personal relationship with God.

In recognition of his virtuous life and dedication to the Church, the cause for his canonization was introduced, and he was declared a Servant of God.
