The Dimonds and MHFM ... hold that those who obstinately accept the Vatican II antipopes (i.e. in the face of the evidence) are heretics.
Ok, here's a few questions that I have, that i've never gotten an answer to, from any Sede.
1. What does "accepting" a papacy mean? This needs to be defined VERY well, for it's open to a LOT of interpretation.
2. Does rejecting a papacy allow you to split the papacy between the spiritual and temporal powers? (i.e. spiritually, a heretical pope loses office, but he still holds the temporal office of governance, until removed by a council?...which is probably what is happening today).
3. Does the "rejecting" of a bad pope happen in the internal forum only (i.e. mental) or must it be public?
4. If public rejection is required, how often? By what means? Do I have to tell someone? Do I have to start a website? Take a blood oath?
5. What if I change my mind or waffle in the decision? Must I go to confession? What would i confess?
6. Does rejecting a V2 pope restrict me from attending any Trad masses?
a. Assuming you believe that an 'una cuм' mass is wrong, then the answer is "yes, you can only go to masses where the priest does NOT pray in union with the pope".
b. If you don't believe that the 'una cuм' prayer affects the morality of a mass, then the answer has to be "No, you can go to any valid tridentine mass".
7. Most importantly, where in canon law does it require any catholic to make a determination on the papacy, with moral consequences?
a. Where in the catechism is anyone taught this requirement?
b. HOW does one properly discern such things? Is there a theology manual somewhere? What rules govern this decision?
