individual bishops may excommunicate as they see fit. My point was the change in the Code of Canon Law 1983 edition. Under the 1918 code free masonry was listed as an ex communicable offense. Under the new code it's not. In addition, then cardinal Ratzinger himself pointed out that while this was the case mbership was a grave sin.
The catholic encyclopedia is a great tool. But current documents have to be examened. I love my Raccolts for example, but many of the prayers in it are no longer indulgenced.
