Let's think a minute.
What we do if we were Bp. Williamson?
Okay, resources are limited, but Our Lady will intercede for us:
1. Do an accounting of all the independent/SSPX Resistance chapels and find out what they need?
2. Recruit new priests and seminarians and confirm their formation and orders.
3. Develop a seminary "fast track" formation program. Be practical, you can compress it from 6 years to 5 or 4. ( We're in. Crisis... right?). Start the priestly mentoring of seminarians ( one-to-one).
4. Institute standardized Catechism programs for the faithful, young & old. Delete the heresies, e.g., "implicit Baptism for those of good will".
5. Hold regional Resistance conferences, at least two per year.
6. Organize resources and accommodations for priest
coming into Resistance tradition.
7. Coordinate priestly assignments to Resistance chapels.
Etc. ...etc.
Some of this is good, but some of it is impossible now, because the Resistance in the USA = Bishop Zendejas.
1 priest/bishop.
To the extent there really is something called the Resistance, it exists largely in France and the Philippines, and perhaps Brazil.
In America, it exists mostly only on the internet.
If you go back and scroll through the Resistance Writings compilation, most of those priests haven't been heard from in 5+ years.
Some people get mad that I am always lobbying for the SAJM or MCSPX (i.e., some kind of hierarchical congregation), but it is because that is the only way to preserve and persevere in anything: Outside of those two groups (excepting the Benedictines and Dominicans), there is no hope for anything, just a slow death.
All those Resistance priests of 2012-2013 went independent, and nobody ever heard from them again.
But to the extent there are any Resistance vocations at all, they are almost exclusively at the SAJM, MCSPX, Santa Cruz, and Avrille:
No congregation = no Resistance and no vocations.
That's just one problem with the whole "loose confederation" idea (which is not Catholic).
A loose confederation among congregations, yes. But among independents? Well, you will get what we have today:
Nothing.
