I think the problem with “doubtful orders” is terrible. The SSPX should continue to ordain anyone from the NO. I was in the same boat trying to get a priest to see a dying relatives. I actually have had fantastic success with all of the SSPX priests I have asked. They do want the person to be receptive of their presence, but all of them have responded. Unfortunately, there wasn’t a priest in close proximity to one of my relatives. I even contacted a sedevacantist priest who said no. However, I ended up getting a FSSP priest to help and was grateful for his support. I hope at least my relative was able to ask forgiveness for his sins, even if they were not able to be forgiven by the priest , since he had doubtful orders imo. Please NO priests, try to receive conditional orders if possible. I am sure it won’t hurt, and will actually allow the Church to be healed.
