In a hypothetical reunion, which schismatic group would be the easiest to bring back to Rome and which would be the hardest?
In a hypothetical scenario where we see a massive momentum toward Christian unity, I’ve been thinking about which groups are closest to and furthest from returning to Rome.
Here is my current take:
The Easiest (Traditionalists): The SSPX probably has the highest chance of returning to full communion. If we go down the rabbit hole, even more extreme offshoots like Sedevacantist Carmelites or the Palmarians *could* theoretically return if they ever "wake up" from their current state, given their Catholic roots.
The Next In Line (Eastern Orthodoxy): After them, my bet would be on some (or all) of the Eastern Orthodox Churches. At the end of the day, both Nicene communions share relatively cordial diplomatic relations. It's clear to almost everyone that, alongside Catholicism, they truly trace their roots back to Jesus and Peter. Plus, the existence of Eastern Catholic Churches already provides a working blueprint for full communion.
So, here is my question for the community:
In a hypothetical universe or historical turning point, which schismatic religion, denomination, or movement do you think would be the absolute hardest to bring back into communion with Roman Catholicism, and which would be the easiest?
Feel free to challenge my assumptions about the SSPX or Orthodoxy too!
