All salvation referred to in Vatican Council II i.e saved in invincible ignorance (LG 16), imperfect communion with the Church(UR 3).,seeds of the Word (AG 11), good and holy things in other religions (NA 2) are either:
implicit or explicit for us.
hypothetical or known in reality.
invisible or visible in the flesh.
dejure ( in principle) or defacto ( in fact ).
subjective or objective.
So one can choose from the left hand side or the right hand side column.
If the right hand side column is chosen then Vatican Council II contradicts the dogma extra ecclesiam nulla salus, the Syllabus of Errors and Tradition in general on other religions and Christian communities and churches. There are known exceptions in 2014 to the dogma on exclusive salvation in the Cathlic Church. The dead- saved are visible.
If the left hand side column is chosen then Vatican Council II does not contradict extra ecclesiam nulla salus, nor Tradition on other religions and Christian communities and churches.
Most people interpret Vatican Council II with the right hand side values.
So the baptism of desire and being saved in invincible ignorance was never ever an exception to the literal interpretation of Fr.Leonard Feeney, unless one is using the right hand side column.There were and are no known exceptions.
In 2014 the Padre Pio Prayer groups, the Neo Catechumenal Way, Charismatic Renewal, all the religious communities and most of the Diocesan priests and the Society of St.Pius X (SSPX) are using the irrational column in the interpretation of Vatican Council II, the Catechism of the Catholic Church and the Letter of the Holy Office to the Archbishop of Boston 1949.
