To be honest, neither the Resistance nor the SSPX has produced much fruit.
The Resistance after 13 years:
- Main men Pfeiffer and Hewko off in the woods some place.
- Other main man Fr. Chazal - how many vocations in his seminary?
- How many priests has the Resistance produced after 13 years?
The SSPX after 50+ years:
- Got into bed on the quiet with GREC basically right after +Lefebvre died - ouch
- Fellay/Vasal, etc., covering up and moving around pervy priests
- Loses a huge percentage of priests they've ordained and don't conditionally ordain others
- Huonder lol
Not produced much fruit? Since the SSPX started from nothing and is now all over the world, and the Resistance which came from the SSPX and is still growing - that is fruit. Even many (most?) of the sede groups with valid priests and bishops came from the good Archbishop Lefebvre's SSPX.
Consider that there was a time in the beginning of this crisis that you could not find a priest, or a Mass and sacraments anywhere, because the very, very few that were around hid themselves - but that all changed with the birth of the SSPX. So please don't say they haven't produced much fruit.
Your post above demonstrates the devil will never stop using his "Divide and conquer" tactic, he works hardest on those trying, the others not so much.
