Indeed, a good article from Dr. Lamont for One Peter Five. I write for 1P5 and it's nice to see how seriously Catholic the folk there are. But there's no question of him "attacking the SSPX", rather serious Catholics are thinking together of how best to deal with these heresies. Fr. Gleize's point is more that, for the last 50 years, there have been errors coming from the Council; this was also what Fr. Pagliarani said recently, "we cannot allow the point of reference to go back than Saint John Paul II" or something close to that. Dr. Lamont is saying Pope Francis has shown himself, in some ways, more hostile to Traditional Teaching than his predecessors. Dr. Lamont and the other signatories of the Open Letter urge the Catholic Bishops to take remedial measures for correcting the Pope. The ideal way for all of this would be settled would be, for e.g. the Pope correcting himself, or a Successor correcting him, as Pope John XXII's error on the Beatific Vision was corrected by his Successor.
