These individuals have provided profound insights into the Christian faith, helping to clarify and explain essential beliefs.

There are currently 37 Doctors of the Church, including notable figures such as St. Augustine, St. Thomas Aquinas, and St. Teresa of Avila. Their works are studied for their depth and clarity, serving as important resources for both clergy and laypeople in understanding the complexities of Christian doctrine.
