This book offers an English translation of the document of the Congregation for the Doctrine of the Faith, accompanied by five comments explaining the importance of the document.
The Congregation for the Doctrine of the Faith (CDF) (Congregatio pro Doctrina Fidei), previously known as the Supreme Sacred Congregation of the Holy Office, and sometimes simply called the Holy Office is the oldest of the nine congregations of the Roman Curia of The Catholic Church. Among the most active of these major Curial departments, it oversees Catholic doctrine. The CDF is the modern name for what used to be the Holy Office of the Inquisition.
