?? I don't understand your question. Catholic clergy are those with canonical mission. Of course the masses they offer are valid.
When you refer to Catholic clergy with canonical mission, is that strictly novus ordo clergy?
The novus ordo is an anti-Catholic sect hatched by ʝʊdɛօ-Masonry in 1958.
Yes, so just make sure that as of 1958 you only attended the Masses of non-sect clergy and only confessed to clergy who recognized that a new sect had been founded and who testified publicly that they were not part of it.
That leaves out Siri...and everybody else.
