Lots of Catholics on FR have already answered this question of yours, in countless threads across the years. Yet, somehow, you fail to understand, and must continually ask. Why should anyone bother, anymore?
It only makes sense that they must denigrate what we believe in: the Faith. The Mass and Christ’s own Church are the only things keeping this world and creation from slipping into the Abyss. Remember St. Pio’s statement: “It would be easier for the world to survive without the sun than to do without Holy Mass.”
The OPC is just another front for FreeMasonry. Just as the FreeMasons call the Almighty Eternal One, “The Architect of the Universe”, so also do the Calvinists.
Calvin, in his Institutes of the Christian Religion (published in 1536), repeatedly calls the Christian god “the Architect of the Universe”, also referring to his works as “Architecture of the Universe”, and in his commentary on Psalm 19 refers to the Christian God as the “Great Architect” or “Architect of the Universe.
I have no doubt that the FreeMasons took some of Calvin’s thoughts into their own particularly peculiar practices and beliefs and agendas.
Rev. James Anderson, Calvinist, btw, in 1723 wrote the definitive rules and Constitution for FreeMasonry, “The Constitutions of the Free Masons; containing the History, Charges, Regulations, &c. of that Most Ancient and Right Worshipful Fraternity. For the Use of the Lodges. London. In the year of Masonry 5723, Anno Domini 1723.”
Anderson was also Grand Warden of the Grand Lodge of London and Westminster. FreeMasonry and Presbyterianism have a long history of going hand-in-hand.
Freemasonry is incompatible with the Catholic Christian faith or any Christian faith. It’s syncretist; beyond heresy into paganism. Historically, one of Masonry’s primary objectives has been the destruction of the Catholic Church. But, it is not for that reason alone that the Church calls it destructive and soul deadening. It’s indifferentism by a great order.
The incomprehensible hatred and loathing of the Church by OPC when viewed from these facts becomes more clear.
There is a very strong history of Freemasonry in the Presbyterian clergy and in their followers.
