51 The same veneration the Bishops should endeavor daily to increase and perfect among the faithful committed to their care, encouraging all those initiatives by which men, filled with apostolic zeal, laudably strive to excite and foster among Catholics a greater knowledge of and love for the Sacred Books. Let them favor therefore and lend help to those pious associations whose aim it is to spread copies of the Sacred Letters, especially of the Gospels, among the faithful, and to procure by every means that in Christian families the same be read daily with piety and devotion; let them efficaciously recommend by word and example, whenever the liturgical laws permit, the Sacred Scriptures translated, with the approval of the Ecclesiastical authority, into modern languages; let them themselves give public conferences or dissertations on biblical subjects, or see that they are given by other public orators well versed in the matter.
