Magister (Latin, "teacher") denotes a master or person entitled to teach in a medieval university. In some systems of higher education it is the name of a degree, such as a B.A., M.S., PhD, M.Phil., or MD.
The feminine form of Magister is Magistra.
For example: the May 15, 1961 Encyclical of Pope John XXIII On Christianity and Social Progress is entitled Mater et Magistra ("Mother and Teacher"), from the first words of the body of the official Latin text:
- "Mother and Teacher of all nations—such is the Catholic Church in the mind of her Founder, Jesus Christ..."
A Master Teacher in some mystery religions or new age circles and esoteric groups may hold the official title of Magister, or in other groups or circles which do not use this title he or she may be respectfully addressed or referred to informally as "Magister", or as a "magister" or one of the "magisters".
