I certainly do not understand this.
I grew up during the reign of Paul the VI and from my earliest memories it was not permitted for a catholic to be a member of the Freemasons.
Even today one can not be a member of the Knights of Columbus and a Freemason.
So how is it that Paul VI opened the church to Freemasonry?
A few years ago I attended a Masonic funeral service in a Catholic parish hall for a man who had been both a Catholic and a Mason--but he had been a Mason before he converted to the Catholic Church. There was nothing anti-Catholic in the Masonic ritual that they went through. Probably there are many Masons who are unaware of the traditional anti-Catholicism of Freemasonry.
Andrew Jackson was a Mason but he appointed the first Catholic Chief Justice of the United States, Roger Taney.
Back about 1959 the Catholic newspaper Our Sunday Visitor ran a series of articles on anti-Catholic groups in the US--one of the articles was about the Masons.
