The CMRI does not have valid priests?

Dear Mr. & Mrs. K., You are not correct about this. Paul IV’s Bull is referring to acts proper to an office; he is not referring to the administration of the Sacraments. It is heresy to say that heretics cannot validly consecrate the Eucharist. This is why the Church has always acknowledged that heretics like the Greek “Orthodox” have valid priests and valid Masses. A heretic can also absolve from sins in certain situations, which is why a Pope and Saints have taught that a Catholic could even go to a Greek “Orthodox” in danger of death. Someone has clearly misled you in this area. The CMRI is definitely heretical, that is clear, and so no one is required to attend their Masses, but their priests are valid and their sacraments are valid. It seems as if you have been speaking with some of the heretics in the Northwest who promote the idea that none of the traditionalist priests have jurisdiction, which is completely wrong. Almost all of those people also deny the dogma Outside the Church There is No Salvation, by the way.
