Our opinion is that you must follow God’s lead on this one. When (not if) you and you family’s Faith is being undermined and destroyed by staying inside the SSPX then you must be prepared to lead your family and leave. We should be prepared to travel, to hunt out a Mass.
Priests will come to serve those who NEED the sacraments - that is how the SSPX get their emergency faculties and that is how Resistance priests obtain their faculties. If all you can offer them is a room in your house, or a site demountable on a piece of land that is all that you will need. You can build up the rest to offer glory to God later… I would advise that you build up a loyalty to a Mass centre and have a hierarchy in your mind of what you will and will not compromise on (in terms of pastoral advise and on doctrine) and reassess as the years creak on by.
We have our recusant persecution as example on how to behave. They had a valid TLM offered by validly ordained priests - the martyrs did not assist at Masses offered by these Henrican priests who served the old and the new regime, in Britain there were faithful who sat both sides of the fence - THEY did not save their souls (or the souls of those they had authority over!) by going to these insulting Masses. (Just google Lord Stourton 1596(ish) and Mortal Sin!)
The main thing is Keep Holy the Sabbath because that is God’s command, going to Mass is a man made rule of the Church and if the Church cannot provide an uncompromised Mass that is not your fault.
Stay strong - hold each other up!
In Him
