Benoit, O.P., Yves de Montcheuil, S.J., Gerald Vann, O.P., Cardinal Newman, Archbishop Goodier and the distinguished editors themselves contribute to the formation of a book on Catholicism that has great depth, clarity, internal consistency and existential import. The second section provides the reader with first-hand sources of information and material to be savored for its beauty and truth in the form of ""the documents"" of Catholicism, such as the various creeds that have been formulated, the texts of the Mass, of the rites of the Sacraments, and of the liturgical and devotional prayers in use in the Church, excerpts from the great books of Catholic spirituality, and quotations from modern papal pronouncements.
