Today in 1906, Pope St. Pius X issued the encyclical Pieni L’Animo, which focused on the clergy in Italy. Here’s an excerpt:
Let the seminaries be jealously guarded in order that a proper atmosphere will be maintained. Let them always be destined exclusively for preparing youths, not for civil careers, but for the noble vocation of being ministers of Christ. Let philosophy, theology, and the related sciences, especially Sacred Scripture, be studied along the lines of pontifical directives: according to the teaching of Saint Thomas which Our venerable Predecessor so often recommended, and We Ourselves recommended in the Apostolic Letter of January 23, 1904.
