Feeneyism:It is the old theology and philosophical reasoning which says there are no known exceptions past or present, to the dogma extra ecclesiam nulla salus (EENS).There are no explicit cases to contradict the traditional interpretation of EENS.It is practical. There obviously are no known cases of the baptism of desire (BOD),baptism of blood(BOB) and being saved in invincible ignorance(I.I) in 2017.So there are no practical exceptions to EENS.Neither was BOD,BOB and I.I an exception to Feeneyite EENS in 1949 when the Letter of the Holy Office was issued to the Archbishop of Boston. The cardinals made an objective mistake.Similarly mentioning BOD and I.I in Vatican Council II (AG 7,LG 14) relative to the traditional teaching on salvation was superfluous.
Cushingism: It is the new theology and philosophical reasoning.It assumes there are known exceptions, past and present, to the dogma EENS, on the need for all to formally enter the Church.It assumes that the baptism of desire etc are not hypothetical but objectively known.In principle hypothetical cases are objective in the present times.
We can interpret Vatican Council II and the Catechism(1994) with Feeneyite or Cushingite theology and the conclusion is different.
The CDF uses Cushingism.The Jesuit Missionaries and I use Feeneyism to interpret the Nicene Creed.
It is the same Creed today (2018) but our understanding and interpretation of it is different.
Check the blog Eucharist and Mission(Lionel’s Blog) for Nicene Creed(right hand column). Also check Vatican Council II(Feeneyite) and Vatican Council II(Cushingite). At least for yourself end the doctrinal confusion.-Lionel
