I am no expert, but John XXIII is the first of the popes whose orthodoxy I question.
:applause:
It's been said that Pope Piux IX made one "off" comment and he spent years living it down.
Pope Leo XIII made have made a blunder in the political realm but that's not theological.
With Pope John XXIII and the conciliar posts, you have to sift through everything they say because at last 20% of what they say is "off" and some of it has you scratching your head saying "Say, that seems pretty close to heretical. Am I seeing what I'm reading?"
