I don't claim to be any kind of theologian, so I'm not inclined to comment on whether specific Popes adhere closely to "orthodoxy" or not. But it is quite clear to me that Pope Francis, at least, is not a particularly good Defender of the Faith. His intellectual arguments are weak and his moral positions on a range of issues appear to be steeped in the gospel of Social Justice, not the Gospels themselves.

Again, I could be off base; my knowledge of Christian orthodoxy is pretty poor. But I get the distinct impression that the current Pope is the weakest that the Church has had for a long time. And if history is any guide, weak Popes are disastrous for the Faith.

I think that is why Benny 16 renounced… he was probably forced to do so by the bishops who were terrified at his willingness to look past their bullshit.
Franky, of course, is a totally controlled tool that endorses heresy at every opportunity. While he may not be the 'false prophet' of revelations (revelations have been 'current' far too many times to take them seriously), he is absolutely the enemy of both the catholic and christian faith, and thus the culture that has sprung from those faiths.
