In other words, +Schneider appears to have created a new, third position.
But supposing, per impossible, the cardinals declared Francis a heretic, yet bizarrely continued to honor the alleged legitimacy of his pontificate, despite being a declared heretic, would it not be tantamount to believing a non-Catholic can be pope?
In that case, there is no principled reason why the Dalai Lama or antichrist could not be legitimate popes (and have not all the theologians been unanimous in their agreement tgat a oooe must at least be a Catholic man)?
