I assume the expression "Unite the Clans" comes from the famous movie Braveheart (1995, starring Mel Gibson).
It's one of those soundbites that SOUNDS GOOD until you give it more than 60 seconds' thought. It's a slogan for the current age, the age of distractions, the age of clickbait, Social Media, and shallow slogans and propaganda.
But to return to my point --
In the movie "Braveheart", the Scottish nobles' constant in-fighting weakens the Scottish cause and allows the English to run roughshod over them, dominate them politically and militarily, and make their lives miserable.
But in that movie (historical reality aside), there was a clear leader that everyone would and SHOULD rally around: Robert the Bruce.
In the Crisis of the Church, and the world of Tradition, there IS no such leader or heir-apparent. There is no one that stands out as different from everyone else. All are doing the same things, with the same justifications: practicing pre-Vatican II Catholicism, offering Mass and pre-V2 sacraments despite lack of Roman permission and in some cases in defiance of Roman authority, etc.
I'm serious. In all of Traddieland, who is the heir-apparent of rightful Church Authority, who all the other Trad groups, priests and bishops should bend their will to and follow if they were smart?
Who, in all of Traddieland, has God appointed and annointed as the one we all should follow? Unfortunately for us, the reason the Crisis has continued so long, is because God has not done this yet -- such is God's will. God has chosen, as part of the punishment and for His greater glory, to "stay out of it" thus far.
If God wants the Crisis to continue, who am I to withstand God?
But the idea that the scattered sheep should have solved this on their own by now -- that scattered sheep in dozens of lifeboats *clearly* should have all followed the leader of lifeboat #37 as their new king -- that argument holds zero water and no one can expect that of any human being. Each lifeboat full of sheep is just trying to survive. All the lifeboats (chapels, priests, bishops) are essentially equal.
Essentially, there is no difference between the greatest SSPX chapel with $5 million of real estate value, hundreds of parishioners, millions in the bank, a 30-year history of operation -- and a small mission chapel with 25 parishioners, monthly Mass, inferior equipment, minimal decor, and founded less than 5 years ago. Looking at the accidents, the SSPX chapel is superior in almost every way. But fundamentally, in all the essential elements, they are equal.
In fact, there is no guarantee about who is right and wrong about anything during the Crisis. All we have is pre-Vatican II writings, manuals, and the words of the Saints -- but we all know how inadequate that has been to break up all disagreements in the world of Tradition...
