Patron Saint of Astronomers

Category: Science & Technology

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 "Astronomers" 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 Dominic is invoked as patron of astronomers. Saint Dominic was born Domingo de Guzman at Caleruega in Castile in 1170, of the noble Guzman family. He received his early education under his uncle, the archpriest of Gumiel, and his higher studies at the University of Palencia, where he distinguished himself by selling his books and parchment manuscripts to feed the poor during a famine.
