I’ve gone to SSPV and received absolution and Communion, WITH PERMISSION OF A SSPV PRIEST, not Fr. Jenkins. Nobody from the laity interrogated me. Yes, I still sometimes attend SSPX if they’re the only ones in town. If I saw a doubtful priest from novus ordo or it was in a novus ordo church, I’d make it a solo read your Missal and extra prayers day. There are some matters I do not believe anyone, be he priest or even bishop has the authority to bind the faithful in conscience until we have a pope who professes the Catholic Faith.
Of course, if the priest turns denies me the Sacraments, if there’s sin, it’s on him. If the faithful are fanatics and heave garbage at me or attempt to burn me at the stake in the parking lot, I’ll do them a favor and leave lest they add assault and murder to the sins of rash judgment or Jansenism.
