Roberto dei Mattei, Christopher Ferrara, Fr.Nicholas Gruner, John Vennari, Louie Verrecchio, Ann Barnhardt, David Domet, Eric Sammons and Michael Matt, were all interpreting Vatican Council II with the Boston Heresy. It was the same with Mons. Brunero Gherardino, Mons. Joseph Clifford Fenton, Fr. John Hardon and Fr. William Most. This was the mistake of Archbishop Marcel Lefebvre and the SSPX and SSPX Resistance bishops.

 Roberto dei Mattei, Christopher Ferrara, Fr.Nicholas Gruner, John Vennari, Louie Verrecchio, Ann Barnhardt, David Domet, Eric Sammons and Michael Matt, were all interpreting Vatican Council II with the Boston Heresy. It was the same with Mons. Brunero Gherardino, Mons. Joseph Clifford Fenton, Fr. John Hardon and Fr. William Most. This was the mistake of Archbishop Marcel Lefebvre and the SSPX and SSPX Resistance bishops.

The Boston Heresy is the rejection of the past ecclesiocentrism of the Catholic Church, it puts aside the dogma extra ecclesiam nulla salus (EENS). It re-interprets the Nicene Creed and the Catechisms of Trent and Pius X. It does this by confusing invisible cases of the baptism of desire and being saved in invincible ignorance as being visible examples of salvation outside the Church and so practical exceptions for EENS and the past ecclesiocentric ecclesiology of the Church. It is a subtle philosophical mistake which produces a New Theology which says outside the Catholic Church there is known salvation; there is salvation.

The Boston Heresy of the 1949 Letter of the Holy Office to the Archbishop of Boston (LOHO) is there among the traditionalists and liberals.

Bishop Robert Barron interprets LG 16 with the Boston Heresy and then says not everyone needs to enter the Catholic Church for salvation, as if he can judge an exception for the dogma EENS. So he says that we can have a reasonable doubt that most people are saved.

Michael Voris, like the SSPX, goes back to Tradition, to the popes and saints and says most people are oriented to Hell, since they die outside the Church and with mortal sins on faith and morals. I agree with him. But Michael trips himself on Vatican Council II which he interprets with the Boston Heresy of Pope Pius XII. He contradicts the pre-1949 popes and saints on EENS.

Cardinals Kasper, Muller and Brandmuller in Germany and bishops Dominique Rey and Roland Minnerath in France interpret Vatican Council II with the same common irrationality.

The Boston Heresy is an objective error which 

can be verified in public. I avoid it. - Lionel Andrades
