Let's concede, for the sake of argument only, that the Church teaches Baptism of Desire. Let's look at the sources Ambrose compiled on another thread that allegedly teach BoD. In each case, I will point out that the teaching in question limits BoD to the very specific / concrete case of THE CATECHUMEN.
St. Augustine -- catechumen
St. Ambrose -- catechumen (Valentinian)
BoB Fathers -- catechumens
St. Emerentiana et al. -- catechumens
Innocent III -- more than catechumen ("priest not baptized")
St. Thomas Aquinas -- catechumen-like persons (those with explicit Catholic faith)
Council of Trent -- catechumens
Catechism of Trent -- catechumens (adults preparing for Baptism)
St. Robert Bellarmine -- catechumens (question: "Whether catechumens who die before receiving the Sacrament of Baptism can be saved.")
St. Alphonsus -- catechumens
1917 Code of Canon Law -- catechumens
Every single one of these was specifically dealing with the case of CATECHUMENS. Catechumens in the early Church enjoyed a very specific quasi-canonical status in the Church. They were signed with the Sign of the Cross in a formal ceremony and allowed to be called "Christians".
If the Cushingite heretics on this board would limit themselves to BoD for catechumens, i.e. for those who have the Catholic faith and who intended and willed and even planned to become Catholic and receive the Sacrament of Baptism, to those who had all the dispositions as described by the Council of Trent leading up to the famous passage they claim teaches BoD, then I would grant that theirs was an opinion tolerated by the Church and would not call them heretics.
WHEN on the other hand these Cushingite heretics, as they ALWAYS and INVARIABLY do, extend BoD (without ANY authority whatsoever) to heretics, schismatics, infidels, pagans, Muslims, Hindus, Jews, etc. they become heretics in denying the dogmatic definitions of EENS which EXPLICITLY state that schismatics, heretics, infidels, etc. cannot be saved. When the Father(s), Doctors, etc. speak of BoD they are not talking about ANY of these; they're talking about those who are not schismatic, heretic, infidel, Jew, Muslim, Hindu, etc. but rather of those who have accepted the Holy Catholic Faith, i.e. about catechumens.
In the 1700s and 1800s the Jesuits in particular started to dabble in expanding BoD to these classes and began the undermining of EENS that would lead inexorably and inevitably to Vatican II. These are the same Jesuits that dabbled in inculturation, etc. that led to the same Vatican II depravities we see today. These are the same Jesuits that were sponsoring Ecuмenical conferences under Pius XII. Fastiggi in the Sanborn debate points out all these precendents and logical antecedents to Vatican II.
Bishop Williamson rightly traces the modern evils of Vatican II to the rise of subjectivism that starts in the Renaissance.
You Cushingite heretics always dishonestly quote these sources above as PROOF for your false allegation that the Church teaches how non-Catholics (heretics, Muslims, Jews, pagans, etc. can be saved). Consequently, most so-called Traditional Catholics promote the VERY SAME heresies in Vatican II. Consequently, they're schismatic for rejecting Vatican II. +Lefebvre, +Fellay, +Sanborn, +Kelly, +McKenna, CMRI, SSPX, etc. have all gone on record saying that non-Catholics (heretics, pagans, schismatics, Jews, Muslims, etc.) can be saved and therefore have publicly embraced and taught HERESY !!!
You guys claim to be defending the Church's magisterium wherein point of fact you're heretics who deny the dogma that OUTSIDE OF THE CHURCH THERE IS ABSOLUTELY NO SALVATION. Your theology is no different than that of Karl "Anonymous Christian" Rahner. Your ecclesiology / soteriology is no different than that of Vatican II. You are enemies of the Catholic Church and the Catholic Faith, not its defenders.
