Honestly though Plenus, if we recommend people to go to SSPX Masses, even on a "case by case basis", it's going to be difficult to motivate people to support them. Because by doing things like that we completely undermine the Truth of our position.
SSPX is morally equivalent to the Resistance by this logic.
I don't think this is the way to uphold truth, and I don't think this is Catholic logic.
In 19th century France, for example, do you think you would have been exonerated by the episcopal authorities from not fulfilling your Sunday obligation because your only option for Mass was one of the countless liberal or Gallican priests? Do you think Pope Pius IX would have commanded you not to attend the Mass of Archbishop Darboy, for example?
I think that is a valid comparison? Gallicanism and Ultramontanism are not morally equivalent, nor were they before the First Vatican Council.
