"Hi Lou! Happy New Year! Loved your write up on St. Raymond of Penyafort (patron of canon lawyers!). The publication of the Decretals of Gregory IX took place in 1234, not 1274-- indeed, the stamp for the International Juridic Conference that took place in 1934 was for the seven hundredth anniversary of that publication, as the stamps themselves note, "VII saeculo a decretalibus Gregorii IX promulgatis." Those decretals, which came to be called the Liber Extra were indeed a major reference point for all canon laws that followed, as you noted." (bolding added for emphasis)
