The Sources of Catholic Dogma (by Denzinger)

The Sources of Catholic Dogma, commonly known as Denzinger’s Enchiridion Symbolorum, is a foundational compilation of doctrinal texts, papal encyclicals, conciliar decrees, and other authoritative statements from the Catholic Church’s history. Assembled originally by Heinrich Denzinger in the 19th century, it has been expanded and revised through the years to include documents up through the 20th century.
