Evolution of Canon Law

The Corpus Juris Canonici (complete body of Canon Law) was codified during the 11th century by clerics associated with the University of Bologna. In previous centuries Church laws were based on a set of Ancient Canons that had been voted on by Church councils. The Corpus Juris Canonici has been appended, revised, and reissued several times, most recently in 1983. The Evolution of Canon Law to its modern form proceeded as follows:

Ancient Canons (to 1050 A.D.)

Decretum Gratiani (~1150)

Decretals Gregorii IX (~1250)

Post-Tridentine Revision of Corpus Juris Canonici (1582)

Pio-Benedictine Revised 1917 Code of Canon Law (Pius X, Benedict XV)

Johanno-Pauline 1983 Code of Canon Law (John XIII, Paul VI)
