Mighty Joe Young,
Thank you for your interest and comments.This is a very important subject.It is necessary that the Catholic Church issue a clarification on this subject.
I respect Monsignor Fenton, Fr.William Most and others, who as good Catholics and with good intentions, accepted the Letter of the Holy Office 1949.
However the principal error that the Letter made was factual and not theological.
The Letter used a false premise, a false proposition. Then it built a new theology upon this objective error.
The Letter assumed that exceptions to the dogma were known and visible to us in real life.In other words they assumed that the dead who are now in Heaven, saved with the baptism of desire or in invincible ignorance, were exceptions to all needing the baptism of water on earth. So for the Letter these invisible cases became explicit exceptions to the traditional teaching of the dogma according to Fr.Leonard Feeney and the St.Benedict Center.
It is a fact of life that we cannot see the dead on earth. It is a fact of life that we cannot see or know any exceptions to the dogma.
This was not noticed by Mons. Fenton or Fr.William Most, otherwise, good apologists.
Even when the confusion was carried over into Vatican Council II,(LG 16 etc) the error from the Letter of the Holy Office, was not detected and corrected.
