Perhaps they simply accept them now as is, I don't know, but they used to investigate each one brought to them and then make some kind of "determination" about whether it was legitimate or not ... which is extremely problematic.
Keep in mind the nature of the SSPX and every other Trad lifeboat. They are there to provide the Mass and sacraments in a time of emergency. Who is welcome? Do you have to look into each person, and see if they are in the state of grace? Or is salvation more-or-less the responsibility of each individual person? The priest is only allowed/obligated to refuse communion to PUBLIC, NOTORIOUS sinners. Like a known prostitute in the town, or a public atheist.
The priest must do his job, yes. He should make us aware of, and feel guilty for, each of our sins. If he fails in this duty, HE will be held to account. But in the end,
it's each person's responsibility to be right with God.Isn't it the worst thing when independent priests/small groups try to "play God" and pontificate about this or that opinion, position, or issue? "You can't receive Communion here unless you ______". That is exactly what priests should NOT be doing.
In the end, the Catholic Church is the great net, enclosing fishes both good and bad.
God will sort them out.Long story short, the SSPX (and others) might be advised to consider annulments legit, but that does NOT mean God is OK with that annulment.
You are responsible for your own soul. You should be concerned what GOD thinks, not the Conciliar Church, the SSPX, a trad group, a trad priest, or your friend group.
