The post-synodal apostolic exhortation on the word of God in the life and mission of the Church, following the 2008 Synod of Bishops and given on the memorial of Saint Jerome. Its three parts are Verbum Dei, on the God who speaks and the human response of faith, with Mary as the model hearer; Verbum in Ecclesia, on Scripture in the liturgy, the homily, lectio divina, and the relationship of exegesis and theology; and Verbum Mundo, on the Church's mission to proclaim the word to the world, in dialogue with culture, in commitment to justice, and in the care of creation.
