I was reading The Decline and Fall of the Roman Church by the late Fr. Malachi Martin. Fr. Martin was famous for his books regarding exorcsim and the third secret of Fatima. He knew about six languages, translated the dead sea scrolls, and his vows of poverty and obedience lifted by Pope Paul VI. He is very popular in traditional cirlces, SSPX included.
Which is why his book is confusing to me. His central thesis is that the current loss of the faith is related to Constantine merging the church and state in the fourth century. I think he argues this never should have happened. However, traditional catholics- especially SSPX advocate for the church/state bridge. Can anyone explain this?
