I'm sure Pope John Paul ll is a good man, however I think that there are evil forces at work in the Vatican and there is a battle going on there as well.
After saying Mass, Pope Leo XIII was privy to a conversation between the devil and God. The devil said he could destroy the church and he could do it in 100 years. God gave him permission to try. After hearing this conversation, the Pope went to his apartment and wrote the St. Michael prayer. This prayer used to be said after every Mass, but no more. By the way, this all took place around the year 1900.
Actually, in 1884. The Prayer was published on 25 September 1888:
SANCTE Michael Archangele, defende nos in proelio, contra nequitiam et insidias diaboli esto praesidium. Imperet illi Deus, supplices deprecamur: tuque, Princeps militiae coelestis, Satanam aliosque spiritus malignos, qui ad perditionem animarum pervagantur in mundo, divina virtute, in infernum detrude. Amen.
