Book excerpt: The Sources of Catholic Dogma is a translation of the Enchiridion Symbolorum. It contains dogmatic pronouncements and decisions of the Councils of the Church and the Roman Pontiffs. This is a valuable tool for anyone who wants to know what the Catholic Church truly teaches. This edition has been corrected, as some slight errors made it into the original English translation. These are noted on the pages and the correction page is appended at the end.
