Sedevacantists say that the Novus Ordo is invalid because they say the new rites of ordination and consecration are invalid.
Let's be clear. This has been explained many, many times, but certain people just can't get it through their heads. I used to think it was an innocent misunderstanding, but I am beginning to think that it is a malicious way to paint all sedevacantists in a desired light for dishonorable purposes.
Sedevacantism means
one thing and one thing only. The current claimant to the papacy, Jorge Bergoglio is not a true pope. There is no other issue that one can pin on "sedevacantists".
What Matto says does certainly apply to many (I'd even be willing to say most) sedevacantists, but it is most definitely NOT true of all sedevacantists. This sedevacantist does not understand why the new rite of orders for priests would be invalid. At most, it is doubtful. The new rite of orders for bishops, on the other hand, is, I am convinced, invalid. Thus, a priest ordained in any rite by a bishop consecrated in the new rite, remains a layman. His Mass would never be valid. I know sedevacantists, however, who completely disagree with me.
Archbishop Lefebvre, in his
Open Letter to Confused Catholics, was very clear in saying that the Conciliar seminaries are so deficient in teaching seminarians that there is less and less assurance that Novus Ordo priests are capable of having the proper intention necessary to produce a valid Novus Ordo regardless of any other factors. This was the reason he felt it necessary to continue to operate seminaries for the SSPX.
While the New SSPX may say that it is valid, it is clear they do so because Bishop Fellay is seeking re-integration with the Vatican and not because he follows the founder of the Society. This is evidenced by the fact that the SSPX used to require conditional ordination of any Novus Ordo priest who wanted to work with the SSPX but no longer does so.
I don't know what people in the Resistance think.
