Catholic Encyclopedia (1913)/Association of Priestly Perseverance
Association of Priestly Perseverance, a sacerdotal association founded in 1868 at Vienna, and at first confined to that archdiocese. In 1879, chiefly through the influence of its periodical organ, "La Correspondance", it spread into other dioceses and countries, and in 1903 counted 14,919 living members, belonging to 150 dioceses in Austria, Germany, Switzerland, and other countries. This organization is very similar to that of the Apostolic Union of Secular Priests (q. v.).
