A Doctor of the Church is a saint recognized by the Catholic Church for their outstanding contribution to theology or doctrine through their writings, teachings, or preaching. Their work is considered exemplary and beneficial for the universal Church.
The title dates back to the Middle Ages, with the first Doctors—St. Ambrose, St. Augustine, St. Jerome, and St. Gregory the Great—officially recognized by the Church in 1298 by Pope Boniface VIII. The designation has since expanded over time.
The Church names Doctors to honor their exceptional wisdom and holiness, and to recommend their teachings as reliable guides for understanding the faith, inspiring both clergy and laity in their spiritual and intellectual lives.
To be declared a Doctor, a saint must exhibit three qualities: eminent learning (outstanding theological insight), a high degree of sanctity (holiness of life), and official proclamation by the Church, typically by a pope or council.
Notable Doctors include St. Thomas Aquinas (philosophy and theology), St. Teresa of Ávila (mystical prayer), St. Augustine (grace and original sin), and St. Thérèse of Lisieux (spirituality of simplicity), among others.
Doctors of the Church provide timeless insights into faith, morality, and spirituality. Their works help Catholics deepen their understanding of doctrine and apply it to contemporary challenges, enriching the Church’s intellectual tradition.
As of March 2025, there are 37 Doctors of the Church, including both men and women from various eras and regions, reflecting the diversity and universality of the Church’s teaching heritage.
No, their writings are not infallible, but they are highly authoritative and aligned with Church doctrine. They may contain personal opinions, but their core contributions are endorsed as trustworthy by the Church.
Catholics can read their works for spiritual growth, such as St. John of the Cross on contemplation or St. Catherine of Siena on charity, applying their wisdom to prayer, study, or addressing modern ethical questions.
