Roman Catholic priest in the context of "Pedro Calderón de la Barca"

Religious activities generally need some infrastructure to be conducted. For this reason, there generally exist religion-supporting organizations, which are some form of organization that manages:

• the upkeep of places of worship, such as mosques, churches, temples, synagogues, chapels and other buildings or meeting places.

Despite being a devout and believing Roman Catholic priest, Fray Luis was descended from a family of Spanish Jewish Conversos and this, as well as his vocal advocacy for teaching the Hebrew language in Catholic universities and seminaries, drew false accusations from the Dominican Order of the heresies of being both a Marrano and a Judaiser. Fray Luis was accordingly imprisoned for four years by the Spanish Inquisition before he was ruled to be completely innocent of any wrongdoing and released without charge. While the conditions of his imprisonment were never harsh and he was allowed complete access to books, according to legend, Fray Luis started his first post-Inquisition University of Salamanca lecture with the words, "As I was saying the other day..."

Heinrich Maier (German: [ˈhaɪnʁɪç ˈmaɪɐ] ; 16 February 1908 – 22 March 1945) was an Austrian Roman Catholic priest, pedagogue, philosopher and a member of the Austrian resistance, who was executed as the last victim of Hitler's regime in Vienna.
