I was raised Catholic and went to Catholic High School but most of my experience with the Catholic Church was post Vatican II. I have only vague memories of kneeling at the Communion rail and having to wear a veil in church. I thought all (Roman) Catholics were the same and did as the pope instructed. I was obviously wrong. Traditional Catholics reject the changes which began with Vatican II and consider the new, modernized church to be more Protestant than Catholic.
They have a point.
The principal architect of the liturgical changes made to the Roman rite was an Italian priest by the name of Annibale (Hannibal) Bugnini. With the help of several Protestant advisers, he created the new liturgy. He became quite powerful in the church and was made an archbishop in 1972. Then suddenly, in 1975, he was dismissed from his position and sent to Iran. Apparently, the reason for his exile was that Pope Paul VI believed him to be a Mason. Catholics consider freemasonry to be an enemy of the Church. So, Hannibal was a Mason.
