Playing the devil's advocate here, since my official position is one of total confusion, and I would not play armchair theologian because I am not qualified to have an opinion.

R&R claim to recognize Paul VI thru Francis as true popes but then, as individuals and often on their own authority or guided by their pet priest, then decide which papal teachings, laws, sacramental rites, or commands are 'kosher', and which can be rejected, resisted or denounced.

It is pointless having such a "Pope".  Besides, I find it difficult (no impossible) to conceive that there will ever come a day when all Trads agree that the new man is a Pope they can all obey and who possesses not only a “Primacy of honour and supreme and full power of jurisdiction over the universal Church, both in matters of faith and morals, as well as in those things that pertain to the discipline and rule of the Church spread throughout the world."

The only answers that make sense to me are

1.  Confusion.  I simply don't know and have no way to know.

2.  The Church is not what it claims to be.

JP2's canonisation removes the first option.  There cannot be a "St". JP2 and St. Pope Pius Xth in any world where I retain my rationality.

Non-infallible canonization is a stupid concept.

This, I am as sure of as that the sun will rise in the morning or that I exist. And I know plenty of SSPX Trads who think the same.  So SVism will get a boost from at least some of them I reckon; if the canonisation goes ahead.

They have told me as much.
