I figured that since you obviously hadn't read the relevant decrees you must have been citing another source. Guess I was wrong.
All the previous laws were abrogated. See the Apostolic Constitution of JP II I posted above.
Are you going to say what books by St. Josemaria you have read to judge his sanctity?
If 2000 years of tradition and canon law was summarily dismissed as you claim and as it appears, the post-conciliar problem is much, much worse than I realized. The process of saintmaking has become a novel creation. Whether the Magisterium has the authority to reinvent Catholicism is the issue.
If I have time I'll go back and research the details. For now, you can have the point.
