Who has the privilege of destroying God's Church? Is it given to Islam? No. Regarding the modern controversies, is it given to the atheistic socialists? No. Pope Blessed Paul VI wrote the new rites. In a certain sense, God's Church must self-destruct. Only God destroys his Church. Nothing really can destroy God's Church but God, because this Church is infallible. So, the great falling away at the end of time, is from God. It appears to be a great falling away, but God also preserves his own Church. There is an orthodoxy preserved, although perhaps not scholastic in nature. This is the mystery of iniquity. No one destroys God's Church but God.
