In the Roman Catholic Church, a Doctor of the Church (Latin doctor, teacher, from Latin docere, to teach) is a saint recognized as having made significant contribution to theology or doctrine through their research, study, or writing. This honor is given rarely, only posthumously, and only after canonization. The Roman Catholic Church has, to date, named 33 Doctors of the Church.
The proclamation of a pope about naming a Doctor of the Church does not mean to declare that the teaching of any Doctor is free from error.
All these Doctors of the Church advanced the knowledge of God through their writing on theology, spirituality, mysticism, or through their defense of the faith in the face of heresy and schism.
The list below includes all the doctors of the Church and where their shrines are located, if any.
The title was first given in the Middle Ages, and originally, there were four great Doctors of the Church:
St. Ambrose (Milan, Italy) 4th century bishop of Milan
St. Augustine (Pavia, Italy) 5th century bishop of Hippo
St. Gregory the Great (Rome, Italy), who was pope at the start of the 7th century
St. Jerome (St. Mary Major, Rome, Italy) the 5th century biblical scholar and translator.
