I’m not even sure if Ratzinger was a valid pope, except in name only.
But I’m 100% sure that “Benedict” resigned in the way he did, to sow discord and confusion, like the heretic Modernist that he is.
So was Benedict the pope until his death? Or is Francis the pope now? Who cares, because they are both Modernist.
Whether we have a temporal-only, Modernist pope or no pope at all - practically speaking, it makes no difference, because either way, the Church is without a true Shepherd. Bad pope or no pope - the end result is chaos, either way.
