Rector of the chief SSPX seminary (Écône) Fr. Bernard de Lacoste stated that it's -- “absolutely certain that priests faithful to Tradition now benefit from a supplementary jurisdiction which allows them to validly absolve all the faithful who come to confess to them.” Says the SSPX-Rome problem is “doctrinal, not disciplinary,” adding –– “What bothers the Roman authorities today is our attachment to Catholic doctrine & our rejection of the errors of the Second Vatican Council. That is the heart of the problem.”
How can a previously invalid punishment today be valid, while what was legally and totally valid be invalid today? It is definitely not logical or sane.
