Isn't that what every Catholic is aiming for? Salvation? I don't see anything mentioning traditions, creeds, masses, rosaries, Eucharists, councils, fallible men declaring themselves and others to be infallible, etc. as making one wise unto salvation. Just Scripture.
Do you think that Catholics think the scripture is NOT able to do that?
The problem with sola scriputra is that it is self-contradicting.
Martin Luther rejected several Catholic beliefs, saying they weren’t scriptural.
The Catholic Church pointed out where our doctrines were in the scripture.
Luther then declared that, if I may paraphrase: “Oh, THOSE scriptures don’t count.”
So the Catholic Church proclaimed the necessity of Tradition to establish which scriptures “count,” declaring the mutual interdependence of Tradition and scripture.
That is, the Catholic Church’s stance is that Tradition, if it were not scriptural, would be unreliable, but that Scripture, were it not Tradition, would be not knowable.
