My understanding of the issue is this. God saves; ONLY God saves, so no one particular human being and no one particular body of humans can claim the power to save. So, whatever concerns those outside of us (the Church), is God's discretion and we (the Church) cannot tell Him what to do. Yet, whatever is within us - the Church - we KNOW; we know that the Church is what is being saved, and as long as I stay with the Church, I am being saved (which does not automatically mean that I will stay with the Church - that requires my own work, effort, will, struggle, training, "askesis," etc.).
That's prolly about it. Best wishes to you and all yours on this Pascha Sunday,
