Father Feeney became famous for his public stand for the dogma Outside the Catholic Church There is No Salvation in the 1940’s and 1950’s.  Most people fail to realize that, at that time, the world’s bishops were by no means staunch traditionalists.  Most of the world’s bishops had already embraced the heresy of indifferentism, which explains why almost all of them signed the heretical Vatican II docuмents just a short time later. ... In fact, during his time, Father Feeney wrote to all of the bishops of the world about the dogma Outside the Church There is No Salvation and received only three positive responses.  In other words, only three of the world’s bishops at that time manifested a positive belief in the dogma Outside the Catholic Church There is No salvation as it had been defined.  It is no wonder that Vatican II went through with virtually no resistance from the Episcopate.

Father Feeney believed and preached the dogma – as it had been defined – publicly in Boston.  He believed and preached that unless a man embraces the Catholic Faith – whether he be a Jєω, Muslim, Protestant or agnostic – he will perish forever in Hell.  Many converted, and many were angry.  He had not a few enemies, especially among the increasingly modernist, politically correct and compromised clergy.

One of his main enemies was the Archbishop of Boston, Richard Cushing, a B’nai Brith (Jєωιѕн Freemasons) man of the year, and someone who called the dogma Outside the Catholic Church There is No Salvation “nonsense.”  In April of 1949, Cushing silenced Fr. Feeney and interdicted St. Benedict Center (the apostolate affiliated with Fr. Feeney).  The reason given by Cushing was “disobedience,” but the real reason was Father Feeney’s public stand for the dogma Outside the Catholic Church There is No Salvation.  It was not due to Father Feeney’s stand against the theory of baptism of desire either, since this wasn’t first published until 1952.  Cushing’s dissatisfaction with Fr. Feeney was strictly based on Father Feeney’s stand for the defined dogma that only Catholics – and those who become Catholics – can be saved.

Cushing had allies with other heretical clergymen in Boston, the area where the controversy erupted.  Father John Ryan, S.J., head of the Adult Education Institute of Boston College, stated in the fall of 1947: “I do not agree with Father Feeney’s doctrine on salvation outside the Church.”  Father Stephen A. Mulcahy, S.J., Dean of the College of Arts and Sciences of Boston College, termed it: “Father Feeney’s doctrine that there is no salvation outside the Church.”  And Father J.J. McEleney, S.J., Provincial of the New England Province of the Society of Jesus, told Father Feeney in a personal meeting, that he was being ordered to transfer to Holy Cross College because of “Your doctrine.”  Father Feeney quickly responded, “My doctrine on what?”  To which Fr. McEleney replied, “I’m sorry, we can’t go into that.”
...
On December 2, 1948, the President of Boston College, Father William L. Keleher, S.J., held an interview with Dr. Maluf, who was an ally of Father Feeney in the stand for the dogma.  Fr. Keleher stated:
“Father Feeney came to me at the beginning of this situation and I would have liked to do something except that I could not agree with his doctrine on salvation… He (Fr. Feeney) kept repeating such phrases as ‘There is no salvation outside the Catholic Church.’”
...
On April 13, 1949, Fr. Keleher (the President of Boston College) fired Dr. Maluf, James R. Walsh and Charles Ewaskio from the faculty at Boston College for accusing the school of heresy against the dogma Outside the Church There is No Salvation.  In his April 14 statement to the press explaining the reason behind their dismissal, Fr. Keleher stated:
“They continued to speak in class and out of class on matters contrary to the traditional teaching of the Catholic Church, ideas leading to bigotry and intolerance.  Their doctrine is erroneous and as such could not be tolerated at Boston College.  They were informed that they must cease such teaching or leave the faculty.”

In fact, I very deliberately avoided any mention of Baptism of Baptism of Desire, precisely to see how many people would interpret that as "Feeneyism", to illustrate precisely what's going on.

Most people don't know that Father Feeney's position on Baptism of Desire came later.

This is what Father Feeney was up against.  Cardinal Cushing:  "No salvation outside the Church?  Nonsense."  (quote from a biographer favorable to Cushing)

Most of the above happened in 1949, and it wasn't until about 1952 that "Baptism of Desire" came up.
