Again, Moral certainty isn't dogma.
Moral certainty doesn't cut it. Take note of the dogma of the Assumption, where the encyclical says:
45. Hence if anyone, which God forbid, should dare willfully to deny or to call into doubt that which we have defined, let him know that he has fallen away completely from the divine and Catholic Faith.Person 1: "They found the remains of Christ's mother in Jerusalem."
Person 2: "It cannot be, because the dogma of the Assumption means Our Lady's body is with her in heaven"
Person 1: "Are your raising to a dogma that the body they found is not Christ's mother?"
Person 2:
"It's not a dogma, but it calls into question a dogma, so it is as CERTAIN and serious as a dogma to deny it is Christ's mother"This is the case with sedevacantists:
R&R: "A pope approved of heresy at Vatican II for the whole Church"
Sede: "A pope cannot approve of heresy to the whole Church"
R&R: "Are you raising to a dogma that these men are not popes"
Sede:
"It's not a dogma, but it calls into question a dogma, so it is as CERTAIN and serious as a dogma to deny these men were/are true popes"
