Sources of Catholic Dogma
Enchiridion Symbolorum et Definitionum, a compilation of sources of Church teaching, has become synonomous with the last name of its original author, Heinrich Joseph Dominicus Denzinger.
Denzinger contains nothing but passages from magisterial writings: the chief decrees and definitions of councils, lists of condemned propositions, letters and other writings from popes and bishops, etc.
Since its first publication in 1854, it has become a standard reference for those looking to see how the Church has continuously taught doctrine.
How To Read Denzinger
Denzinger is not, strictly speaking, a scriptural commentary.
However, Sermonry includes passages from Denzinger that themselves cite the scripture in the propers.
Each paragraph or section in Denzinger is numbered. Since 1963, there are two numberings: the old, Denzinger numbering, and the new, Denzinger-Schönmetzer numbering.
Sermonry uses the old numbering for the main reason that editions using the older editions are out of copyright, and free to reproduce.
