In this age of doctrinal latitude and speculative innovation there is a pressing need for a comprehensive source book on authentic Catholic dogma that is magisterially anchored while at the same time both practical and non-voluminous. You have such a book in this English translation of Father Heinrich Denzinger’s Enchiridion Symbolorum et Definitionum. Since it was first published a century and a half ago, this handbook or collection (enchiridion) of articles (symbols) of faith and morals has enjoyed universal appeal and approbation since the pontificate of Blessed Pope Pius IX. The Enchiridion has been updated periodically; the edition being offered here by Loreto is that issued in 1957. The collection includes all articles and creeds of the Catholic Faith beginning with that of the twelve apostles, all dogmatic definitions stamped with the Petrine authority of the apostolic See (ex cathedra), decrees of the solemn magisterium, papal bulls, encyclicals and letters, as well as some of the more weighty decisions of the Holy Office prior to 1957. Although not every entry in this 653 page compendium of Church teaching is definitional (i.e. ex cathedra) it still should be considered the "locutus est" for every wayfaring Catholic whose patria, this side of heaven, is Roma. In addition to a general index there is a scriptural index plus an invaluable systematic or topical index making for very easy reference. Note, too, this edition comes with a one page Corrigenda which is a list of sixteen corrections that must be applied to errors (usually omissions) that escaped the eyes of editors in previous editions.
