What is CIC 1917 notable for?

• A. First complete codification of canon law for the Latin Church
• B. Introduction of new calendar reform
• C. Translation of canon law into English
• D. Establishment of the Congregation for the Doctrine of the Faith

Answer: (A)

The main idea is that the 1917 Code of Canon Law is notable for being the first complete codification of Latin Church law, bringing centuries of scattered legal materials into one organized, authoritative code. Before this codification, canon law lived in a mix of sources—decretals, papal constitutions, local customs, and earlier collections—without a single, systematic structure. The 1917 code arranged norms into a coherent framework with books, titles, and canons, making the law more accessible, easier to apply, and uniformly binding across the Latin Church. It also marked a modernization of how canon law was produced and applied, centralizing authority and providing clear rules for areas like sacraments, marriage, church governance, rights of the faithful, and ecclesiastical tribunals. This code remained the standard until it was revised by the 1983 Code of Canon Law.

The other options don’t fit because calendar reform is not a matter of canon law, there was no English-language translation as the defining achievement of the Code in 1917, and the Congregation for the Doctrine of the Faith existed long before 1917 (originally Holy Office dating back to the 16th century).
