Anything but sedevacantism.
Actually, I would unironically say
yes, especially in situations like this. When I see this kind of partisan divide-and-conquer it makes me SICK.
"Rah-rah my team. And my team is sedevacantism." What motivates a man to be so partisan? Were sedes responsible for you finding and marrying a wife, or something? Were sedes responsible for your job and/or career? There has to be some human, earthly reason for this motivation.
Because I would say to sedevacantism, "you're no prize yourself". As you mentioned 40 years, 50 years, 60 years -- that's how long of an "interregnum" Sedevacantists say there is. With every passing year, sedevacantism becomes more flawed and unlikely as an answer to the Crisis. The distorted, epic length of "interregnum" is one of the main Achilles' heels of the Sede position. And given the flow of time in one direction -- that Achilles' heel becomes larger with every passing year!
I'm tempted to get all rah-rah MY team and bash sedevacantists right now. But frankly that's become tiresome. Nowadays, instead, I preach in and out of season that
the Crisis in the Church is a supernatural mystery that can ONLY be solved/untangled by Our Lord Himself. DIRECTLY.The answer is not to find flaws in each of the "positions" and stay aloof from all practice of religion -- no, we need the Sacraments. The Faith is a habit of life. We need Mass and the Sacraments. So pick your poison -- the position that seems best to you -- and go with it.
Here's something else to chew on: when you've cut yourself off from, and completely vilified all the other "positions" except yours, you're just ONE BAD PRIEST away from ceasing practice of the Catholic Faith. Imagine if someday you are sorely disappointed in sedevacantism? You would then have nowhere left to turn.
