For FSSP, ICKSP, SSPX, CMRI, RCI, IMBC, SGG
What are the populations of parishioners (including those who live far away and watch online masses from them) for each of these groups?
And what are the numbers of priests/brothers/monks/nuns for each of these groups?
A good question but one I don't think anyone besides God could answer.
The closest to answering your question that we might get would be to categorize which groups are larger or smaller perhaps?
In the U.S. I would guess:
#1. FSSP being largest
#2. Then the F-SSPX
#3. CMRI
#4. IMBC, SGG and Sanborn's groups are smaller but interconnected I think? The Resistance with Bishop Zendejas wasn't mentioned. It probably falls into about the same size of group as one of these? I am sure Matthew or someone else more connected with them knows better than I?
#5. ICKSP and RCI I am not as familiar with... So, I am guessing that they are smaller?
Anyone else have input, suggestions, or corrections for this?
