The Declaration of Truths is meaningless for the liberals, since Cardinal Raymond Burke,Bishop Athanasius Schneider and the other signatories do not affirm the old interpretation of extra ecclesiam nulla salus(EENS). So since the dogma and doctrines on salvation have changed for them, everything is open to change.

The Declaration of Truths is meaningless for the liberals, since Cardinal Raymond Burke,Bishop Athanasius Schneider and the other signatories  do not affirm the old interpretation of extra ecclesiam nulla salus(EENS). So since the dogma and doctrines on salvation have changed for them, everything is open to change.

Cardinal Walter Kasper pointed this out directly a few years back in an interview. He said if ecclesiology could be changed then why cannot the Eucharist  be given to the divorced  and re-married.

In another interview, when he was made a cardinal, he said, that no one today believes in the Eucharist.This is a common liberal line.

Why cannot the Eucharist be given to every one, Pope Francis is now asking?

So since Cardinal Burke and Cardinal Pujac and the other signatories have accepted  that unknown cases of LG 8, LG 14, LG 16, UR 3, NA 2 ,GS 22 etc are personally known exceptions to EENS, this is a new revelation in the Church and so the liberals , other teachings and doctrines can be changed.

They could not say that all non Catholics in 2019 need to enter the Catholic Church to avoid Hell and there are no known exceptions for us humans beings. Hypothetical possibilities are not practical exceptions to extra ecclesiam nulla salus.Vatican Council II cannot contradict EENS, the past exclusive ecclesiology and an ecumenism of return.The Council does not contradict the Syllabus of Errors and the Athanasius Creed.-Lionel Andrades
