You refuse to answer because you know that it'll undermine everything you've been babbling nonsensically about this entire thread.
On the contrary, I acknowledge Pius XII’s legitimacy as a dogmatic fact subsisting in scripture (same as all other popes):
“Tu est Petrus...”
You, on the contrary, highlight your own inconsistency and sectarian arbitrarity by acknowledging Pius XII, but not Francis, yet still muster the effrontery to use the papacy as dogmatic fact argument, even though you reject it!
That is prima facie evidence of your sectarian bad will.
If you would counter by saying that it is I who am inconsistent by arguing that only some canonizations are dogmatic fact, but all popes are dogmatic fact, I respond that whereas all popes have their foundation in scripture, not all canonizations have their foundation/basis in scripture or tradition, and this is why you will not be able to trip me up, and subvert the truth:
Only matters based in faith are proper subject matter for infallibility.
Try as you might, you will not be able to obscure that simple fact
