There’s one mess (mass) we can all agree is invalid.  What next, concelebrating with the Dali Lama?
Or at 770 with R. Yehuda Krinsky?  In the tunnel? 

No, it's not valid to question it.  Matthew unequivocally stated that he has verified the conditional consecration as fact.  You can call Matthew a liar then, but be open about it.  I also have sources who have directly asked Bishop Williamson, and Bishop Williamson confirmed it to them ... and they're not liars either.  Not only that but I've seen it confirmed by Bishop Faure in writing, and it was also confirmed by Father Chazal.
