Most Traditionalists SAY they believe in EENS, with SAY being the operative word.
At the end of the day, however, they interpret EENS the same way Bergoglio does and in this they share the same heresy that's at the root of all the Vatican II errors.
They claim that non-Christians can be saved by following the lights of their consciences. Archbishop Lefebvre, alas, proclaimed this same heresy in his "Against the Heresies".
This is THE heresy of Antichrist. St. John refers to Antichrist as "dissolving Christ". So now Christ is present everywhere in almost a pantheistic way, whereas only Catholics used to be members of Christ. Catholic Church used to be synonymous with the Christ's Body. Now Christ is dissolved and diffused among all "people of good will" everywhere.
Rome will lose the faith and become the seat of the Antichrist. We're there.
Most Traditionalists refuse to see this and are more concerned with whether you kneel or stand during certain parts of the Mass than with this CORE HERESY of our day. There's outrage when SSPX wants to have people stand during the Sanctus. They're more interested in how Bergoglio wore a clown nose or allowed tango at a mass than in the real heresy. They're more interested in the proper dimensions of the lavabo cloth.
