"...schism is the refusal of submission to the Supreme Pontiff or of communion with the members of the Church subject to him." (CIC, 751). “It is imperative for every priest who wishes to remain Catholic to be separated from the Conciliar Church until such time as it has returned to the traditional Magisterium of the Church and the Catholic Faith,” [Archbishop Marcel Lefebvre, ‘Spiritual Journey,’ 1990].
After 15 years of retirement, Pete Vere, is back to analyze the SSPX status. Read here: SSPX Consecrations and Impending Schism - Where Peter Is For those who have been in the Trad world for a while, you may recall Pete's co-authorship of a book with Patrick Madrid, More Catholic than the Pope. This was back when mainstream Traditionalists were not sympathetic to the SSPX. The SSPX, after all, was in competition with the FSSP, ICK, Indults, etc. for the TLM flock. If individuals were pro-SSPX, it was "under the radar".
