Church father

The Church Fathers, Early Church Fathers, Christian Fathers, or Fathers of the Church are ancient and generally influential Christian theologians, some of whom were eminent teachers and great bishops. The term is used of writers or teachers of the Church not necessarily ordained^[1]and not necessarily "saints"—Origen Adamantius and Tertullian are often considered Church Fathers but are not saints owing to their views later deemed heretical^[2]—although most are honored as saints in the Roman Catholic Church, the Eastern Orthodox Church, Oriental Orthodoxy, the Church of the East, Anglicanism and Lutheranism, as well as other churches and groups. The era of these scholars who set the theological and scholarly foundations of Christianity largely ended by 700 AD.

700 AD - 1300 AD

doctor (n.) 

c. 1300, "Church father," from Old French doctour, from Medieval Latin doctor "religious teacher, adviser, scholar," in classical Latin "teacher," agent noun from docere "to show, teach, cause to know," originally "make to appear right," causative of decere "be seemly, fitting" (see decent).

Meaning "holder of highest degree in university" is first found late 14c.; as is that of "medical professional" (replacing native leech (n.2)), though this was not common till late 16c. The transitional stage is exemplified in Chaucer's Doctor of phesike (Latin physica came to be used extensively in Medieval Latin for medicina). Similar usage of the equivalent of doctor is colloquial in most European languages: Italian dottore, French docteur, German doktor, Lithuanian daktaras, though these are typically not the main word in those languages for a medical healer. For similar evolution, see Sanskrit vaidya-"medical doctor," literally "one versed in science." German Arzt, Dutch arts are from Late Latin archiater, from Greek arkhiatros "chief healer," hence "court physician." French médecin is a back-formation from médicine, replacing Old French miege, from Latin medicus.

doctrine (n.)
