I don't follow Taylor Marshall that closely. Did he make up that term, or try to start such a movement ("Unite the clans"), or was he just promoting it from others?
You will note I didn't mention ONCE Taylor Marshall OR Vigano in my original post.
I was criticizing the concept, not any person(s).
Because it's a perennial idea that just won't die within Traddieland, the whole "Why don't we all just get along?" Trad-cuмenism, as it were.
This idea seems particularly popular among those NEWEST to Tradition; they act like they're above it all, like they've thought of something no one has thought of yet. They don't understand some of the fundamentals of the movement, obviously (such as: why would any bishops just capitulate to follow a fellow-bishop, who might be less qualified, educated, and/or intelligent than himself!)
While there IS One True Church (founded by, and supported by Christ Himself, outside of which no one can be saved), you can't say the same thing about the groups in Tradition.
No one can claim to have God on his side personally. They all claim to be doing God's own work, even while they fight each other *fiercely* -- some of them even resorting to committing grave (mortal) sins in the quest to out-compete and grow at the expense of their "rivals". They fight each other over money, parishioners, power, real estate, etc.
I'm not criticizing ALL in Tradition; remember that a man walking down the street could be punched in the face by anyone. Even the holiest of saints. It DOES NOT take two to tango. It depends on what you mean by "tango". If by "tango" you mean "be involved in a fight/controversy" then that could be said about Our Lord Himself, Who was the greatest of saints -- the very model of sanctity (obviously). Remember: even a complete victim is "involved" in an attack or fight. But if by "tango" you mean descend into the gutter and fight dirty, with neither side able to claim the moral high ground, then NO, MOST DEFINITELY this does not apply to all priests, bishops, and groups.
Some priests, bishops and groups fall into a cult mentality: the cult of a personality/group, and putting that group before all, even the good of souls. Telling souls to stay home rather than support my "competitors" for example. That is a good sign you're dealing with a de-facto cult.
