The laity who attend SSPX churches will sooner or later face two choices, unless they lose their faith altogether.
(1) Join the Vatican II church before or after the SSPX joins the Vatican II church in approximately two years unless an awesome miracle happens.
(2) Join the Resistance, CMRI, or one of the other groups of Traditional Catholics.
If all the laity in the SSPX were to pray a novena devoutly before the Feast of the Assumption (Dormition) starting on August 6, 2019, perhaps Our Lady would intercede to Christ our God to save them. However, do not stop praying this prayer, but let it become part of your daily prayers and daily inspiration constantly imploring Our Lady to save us.
REMEMBER, O most gracious Virgin Mary,
that never was it known that anyone who fled to thy protection,
implored thy help, or sought thy intercession was left unaided.
Inspired with this confidence, I fly to thee,
O Virgin of virgins, my Mother;
to thee do I come; before thee I stand, sinful and sorrowful.
O Mother of the Word Incarnate, despise not my petitions,
but in thy mercy hear and answer me. Amen.
