In Catholic tradition, patron saints are holy men and women whose lives and intercession are considered especially suited to particular needs, groups, or situations. The Church's practice of invoking saints reflects the doctrine of the Communion of Saints — the belief that the faithful departed remain united with the living in the one Body of Christ and can intercede before God on our behalf.
The designation of a patron saint for "Professors" reflects centuries of Catholic popular devotion and, in many cases, formal proclamations by popes or bishops recognizing a saint's particular connection to this intention through the circumstances of their life, death, or documented miracles.

Saint John of Kanty is invoked as patron of professors. Jan z Kety, known in Latin as Joannes Cantius, was born on June 24, 1390, at Kety in the foothills of the Beskid mountains of Lesser Poland to a comfortable family of the local burgher class. He studied at the University of Krakow, founded only forty-six years before by Saint Hedwig of Anjou and her husband King Wladyslaw II Jagiello, took successive degrees there, and was ordained priest.
