The following situation is hypothetical, but not without real-world applications. Please do not use this thread to resurrect historical controversies.
Let’s say Bishop (or Patriarch, or Cardinal) Q is the leader of a particular group in communion with the Church.
Due to his frustration with certain actions or policies of the Church, Bishop Q goes into schism and takes his followers with him. Though schismatic, this group does not propagate any heretical teachings.
Pope X, leader of the Church responds by excommunicating Bishop Q.
Several years later (50 or 500, as long as you want), one of Pope X’s successors, Pope Y, decides to try and bring the schismatic group founded by Bishop Q back into communion. Bishop Q’s successor, “Bishop” R, accepts.
As part of the reconciliation, Pope Y lifts the excommunication of Bishop Q.
Now here’s the question:
Being excommunicated, Bishop Q is outside the Church and (presumably) goes to Hell upon his death (unless he repented and confessed / made an act of perfect contrition for the sin of schism before dying.)
**Does lifting the excommunication change this?
Or, given Divine foreknowledge, will God send Bishop Q to Purgatory rather than Hell to be purified of his sin (of schism), knowing that Pope Y will lift his excommunication one day and permit him to be saved?**
Thinking caps on.
