Through reading Church history my dear fellow. He like his successors, St Pius X and Pius XII was a man much maligned by liberals and modernists as he cleared them out. I don't know why you say I am devoted to him, well I do really and it is not working, I have great respect for him, though and his successors whom I named above.
Alas, around 50 years ago the door was left ajar and they have sneaked back in and are causing havoc again but at least we know that they can win. They should know this themselves for Christ promised that, "the gates of hell would not prevail".
