It's very simple.... Abp. Lefebvre started the SSPX in order to continue the line of tradition and to avoid modernism. Bp. Fellay is taking 'tradition' back to 'modernist' Rome where it will be crushed. Remember, the Abp. said that going back to Rome before her conversion would be ѕυιcιdє! Therefore, Bp. Fellay must be resisted if tradition is to continue on. He is allowing modernism to take over the SSPX! Being the highest authority in the SSPX and guardian of tradition makes him the focus.
And, if the resistance is causing a ruckus: mission accomplished! Resistance is shown by making objections heard and by taking action to alert others to the dangers at hand.
Say a prayer, then go to truetrad.com and check under "77 Poisonous Statements" made by Bp. Fellay. There's lots to resist!
What do you mean by "tradition and the Church" need a true resistance?
I and many do not need to be convinced of Bishop Fellay's infidelity. It is an established fact.
And what I mean is a true resistance would have as its center engaging itself against the modernist criminals in Rome, (starting in the papal hotel), in the chanceries, and in the pulpits, who are still moving almost unimpeded, in the continuation of the revolution and the destruction of the Church.
As long as the resistance so called limits itself to Bishop Fellay's modernism, without going beyond the closed circle of the SSPX, it is not a resistance in the context of the larger Church. Bishop Fellay and the Society are now a symptom, not the cause, and the resistance has diagnosed the symptom. The SSPX, as it was, is not coming back.
It is time to turn and confront the cause which now needs to be resisted and overcome, if it is God's will.
