Context, sir...
In regards to the quote above:
1. Bellarmine is talking about a morally evil pope who gives morally evil commands — not one who, like the post-Vatican II popes, teaches doctrinal error or imposes evil laws.
2. The context of the statement is a debate over the errors of Gallicanism, not the case of a heretical pope.
3. Bellarmine is justifying “resistance” by kings and prelates, not by individual Catholics.
4. Bellarmine teaches in the next chapter of his work (30) that a heretical pope automatically loses his authority.
The above is from Father Cekada. I don't agree with a lot of things Father Cekada has to say, but what he states above rings true.
There is an observation made by St. Bellarmine in which he considers the case of a heretical bishop teaching false doctrines. Although a Pope is different from a bishop, the case presented here does give us an insight into the saint's reasoning. He says:
“It is true that the people should discern the true prophet from the false, but not by any other rule than the following: Observe carefully if what he teaches is contrary to what his predecessors have said, [70] or that which is said by other pastors, ordinaries, and above all the Apostolic See and the principal Church; for it is commanded that the people should listen to their pastors: Luke X: He who listens to you listens to me; and Matt. XXIII, do that which they tell you to do. The people ought not to judge their pastors except when they introduce innovations or doctrines which are in disagreement with those of the other pastors.” [71]
“Moreover, it is necessary to observe that the people can clearly discriminate, by the rule that we have given, between true and false prophets. But for all that they cannot depose of a false pastor if he is a bishop and substitute another in his place. For the Lord and Apostle only commanded that false prophets not be listened to by the people; but not that the people should depose them. It has always been the practice of the Church to depose heretical bishops by councils of bishops or by an act of the sovereign pontiffs.”
First, the manner of distinguishing a true pastor from a false one, is nothing but the
Catholic Principle of non-Contradiction. Because we know that God is Truth and Truth does not change, whenever there is a teaching which is contrary to what has always been taught as true, then that it is sign indicating a false pastor.
Second, St. Bellarmine does make a distinction between the loss of Authority and the juridical deposition following it. In the example, the people
can and should judge that a contradiction has occurred, then, as a result, they should refuse listening to the false pastor. He has lost his Authority because he is no longer an instrument of Christ. However, if such a false pastor is not as yet deposed, he must be deposed by proper Authority according to the laws of the Church. In the mean time, he continues to
materially occupy the office.
