If I feel spiritually nourished by the Novus Ordo, should I go? I know, I'll check to see what +Williamson has to say. He's always right.

You bring up an interesting point, his grace Bishop Williamson did say that the Novus Ordo can nourish one’s faith, Bishop Zendejas recent sermon states that the doubt applied is not “systematic” which means it’s not intrinsically evil, which goes against the entire pre-2012 SSPX position.  

+Lefebvre, Father Hesse and others have clearly taught otherwise. 

However just because Bishop Williamson has also said to do what you “need to do to nourish your faith”it does not mean you should take his advice and attend the Concilliar SSPX of Bishop Fellay.
