This Homiliary provides a comprehensive guide to doctrinally based preaching for the entire Church year, presented in the Dominican tradition: a preaching of Scripture which takes doctrine as guide to the clarification of the Bible's main themes. Doctrine is necessary to preachers because in its absence the Scriptural claims and themes do not easily hang together. The grace the Word imparts always has a reference to the Mystical Body which mediates all the grace that is given by Christ as the Head. So, precisely as a fruit of grace, preaching is necessarily related to ecclesial awareness. Doctrine ensures that preaching does not fall short of its true dimensions - expressing the biblical revelation, the faith of the Church.
