Wessex, I know you're complaining that they're not going for "downtown London" anymore, but honestly! The Resistance is in the right. But unfortunately the position goes very much against the World, and so the numbers (and, consequently, available resources) are very small.
It isn't a question of "choosing" a humble residential chapel over a cathedral. Do you really think they have a choice of the two? Like they're just letting their $5 million dollars "chill" while they hang out at a suburban residence for Mass?
Give me a break!
The Resistance is doing all it can, and in my opinion they are doing very much with very little.
Most people aren't interested in the truth. Full stop. This limits our "successes" more than you can imagine. It's not that we're not apostolic, or being too exclusive, being a cult, etc.
No, we're basic Catholics. We're traditional Catholics -- the Catholic Faith is inherently Traditional. And we're a particularly sane branch of Traditional Catholics (following the saintly +ABL's lead -- he grew the largest Trad organization because he attracted all kinds of SANE Catholics to him)
While some criticize R&R for being "have your cake and eat it too" or "sitting on the fence", I call it the golden mean between AND ABOVE the two extremes of Conciliarism and Sedevacantism/Church-vacantism/home-aloneism. I also call it eminently Catholic. Does it leave an element of mystery? Of course! But to me, that's why it's true. Any solution leaving out any mystery in this Crisis is obviously false.
I don't mean to get into a Sede vs. R&R debate; I'm just pointing out that the classic SSPX or ABL position is a very good one. And that is the position represented by the small number of Resistance chapels around the world today. But they are still small, because the world is always on the prowl, trying to win over (or partially win over) Traditional Catholics one by one.
(As an aside, Virtue is not "between" the two vicious extremes, but between AND ABOVE, as I learned in my 1st year Ascetical & Mystical Theology class. For example, superstition is an excess of Faith and apostasy is a deficiency of Faith. So would the "virtuous middle" be to be superstitious sometimes and incredulous sometimes? No, the virtue of Faith is in between but also ABOVE the two distorted extremes.)
So if we have small numbers, it isn't necessarily our fault. People don't want to think, talk about, or discuss what's going on in the SSPX or in the Church. People don't want to be marked "weirdos" for believing in any sort of conspiracy, even though it's eminently provable and reasonable that some men have convened (and are convening) for various secret evil plans.
