What about Gratian and the Corpus Juris Canonici, that wasn't a "codification" in relation to the localized grab-bags of laws that had come before? And those localized grab-bags, that wasn't a codification in relation to what came before, when the laws were probably known by "word of mouth," for lack of a better term, but weren't collected in any one place?
It seems to me that the organization of information has been getting steadily more refined through history, along with the improved means of communication, and that the 1917 Code was a refinement, not a break. Apart from that, I'm no historian of canon law, so I'll shut my trap.
TKGS, besides the editorial board of the Remnant, I can think of a certain other group whose MO is to drag everything about the Church through the mud, often saying, with an accuracy that leaves much to be desired, that "many Popes were heretics" in order to justify the Vatican II impostors. The amount of people who have taken up the art of contortionism to justify formal, manifest heretics who have nearly destroyed the entire Church is a phenomenon of our time that future generations will marvel at -- if it's possible to marvel while crouching over a bucket and puking copiously.
