Ratzinger resigned of his own accord. He's not being 'held prisoner in the Vatican' either (as the real tinfoliers at times assert). It's more like relaxed retirement.
Ann Barnhardt is a whack-job in this particular area, although that's not entirely her own fault-- she's trying to make sense out of something that should have never been (and was not) from the beginning of the Church.
The WHOLE problem is "believing" in what was a lie from the get-go.
A bishop of Rome is no "bishop of bishops" ranked over and above all others. That entire way of thinking is artifice.
Get rid of that idea (of 'Papacy' as those of Rome do define it).
There is no one "Pope" whom all must pay deference to. There was never supposed to be one "Pope" that all must pay deference to.
There is one Father, in Heaven, and that's it. Not that Father plus a human 'Papa' in a religious sense.
Yeah, I get it. You’re not Catholic.
