Maybe Vatican II is leading to the purification of the Church. Why do you assume it was a mistake - that it wasn't inspired by God?
Because I believe it has clearly led people away from the Faith. God might allow that but he would never author a plan that did such.
I too have had that same thought and I believe that is exactly what is happening, the Goats are being seperated from the sheep!! No doubt about it!! Those who are keeping the laws of God and those who are not. Thse who are destroying his house and those who are not. Thank You, Sir!
