Catholics are often attacked by both Satan and other Christian religions. It is my personal belief that, while Satan will attack the Church, if we hold steadfast in our faith in God, and if the Papacy sticks to its guns, we will get through the final days.
God would never allow us to fall to Satan. He loves humanity far too much to let that happen, despite the gift of free will. If this is so, he will not allow the people representing him to fall.
It is my honest opinion that God will protect us in the final days. I have only just started to become Catholic, and I have not yet been received into the Church, nor have I received the Eucharist, but I truly believe that, if we stick to God’s plan for us and be faithful, there will be nothing to worry about.
I have even talked to the priest at my Church, and he says that the Book of Revelations is more of a comfort to mankind, so that we know was is to come.
If I may, I would say, don’t worry about it. Just be a good Catholic and surrender yourself to Jesus. Nobody knows when the hour is coming that God will arrive. All we know is that the believers will be protected by God’s grace.
Why worry about something that you cannot change? Why worry about when Christ comes? Nobody knows when he will come again. Just give yourself to Christ, and let God handle the rest. After all, that is why he is here.
As for Anti-Pope Christians, I don’t know what will happen to them, but God will have already had his mind made up as to what their fate will be when they get there. I don’t know if they will go to Heaven or Hell, but I will say this: God knows what he is doing, so don’t worry about it.
As the saying goes: Let go, and let God.
