Often, the worst judges of Popes are those that are alive during their Papacy, but I think he will be remembered as "The Great." I have been one of his freq. critics because he doesn't excommuncate these Bishops but I am willling to admit that perhaps, just perhaps, he knows a bit more than do I....
It is not like he doesn't know what is going on, so, one has to asume he knows that excommunicating a bevy of Bishops would not improve the situation. While it certainly would make ME feel better if he did defrock a bunch of Bishops , I am positive the Pope knows what is best for the Faith worldwide
