Baptism is the only sacrament absolutely necessary to salvation. If you were put in a gulag for thought crimes against wokeness, would you be able to live without the sacraments? Many saints had to do just that, just like St. Maximilian Kolbe. Of course, I hope we all have the sacraments up to and including our own death beds. But if not, we need to practice living in sanctifying grace for the rest of our lives, even if we were to never meet another priest again.
