See. There is no denial from the Vatican.
1. They agree that Lumen Gentium 8 is not an exception to the exclusivist ecclesiology of the Church on salvation.
2.They agree that all Catholic religious communities and lay Movements can interpret LG 8 as not being an exception or relevant to Feeneyite extra ecclesiam nulla salus(EENS).
Vatican Council II can be interpreted in harmony with EENS as it was known to the missionaries and Magisterium of the 16th century.
Vatican Council II is also in harmony with the Syllabus of Errors and an ecumenism of return.-Lionel Andrades
