I know nothing and I believe it is possible that he was a mason.
What I was trying to express is that if Pius IX was a freemason now every pope can be a freemason and that would be really tiring, so I would want a break from that.
Honestly, I really don't want to now investigate popes before Pius XII.
It was just an off-the-cuff comment, didn't mean to start a discussion.
