Fausto Appetente Die §4

⁴ In the Dominican preaching three qualities shine forth: great solidity of doctrine, the fulness of fidelity towards the Apostolic See, piety towards the Virgin Mother. For although Dominic felt himself mature for preaching, yet he did not undertake that office until he had worked hard in the Palentine Athenaeum of philosophy and theology. Long familiar with the Fathers, under their guidance and teaching, he first, as it were, received into his blood and marrow the riches of Sacred Scripture, and especially of Paul.
