The apostolic digest

Does the Catholic Church today adhere completely to THE APOSTOLIC DIGEST
(A Digest of Tradition) COMPILED BY MICHAEL MALONE?
If so, that presents some very difficult questions concerning some of the statements.
For example: Neither the true faith nor eternal salvation is to be found outside the Holy Catholic Church. (Ven. Pope Pius IX).
It is difficult for me to believe that great Protestant preachers such as Billy Graham are not true Christians and are doomed to Hell.

Perhaps you could focus on the Vatican II documents, specifically UNITATIS REDINTEGRATIO

I must tell you that the church does not adhere to the teachings of a book, since the Catholic Church HOLDS the teachings to which we must adhere, being that, the book must adhere to the teachings of the Church.
