Sola Scriptura means Scripture is viewed as the ultimate authority for the faith. It does not therefore ignore tradition or the Church in discerning truth, rather both of these are subject to God-Breathed scripture.(1)
As for it being a concoction of Dr. Martin Luther, several noted fathers spring to mind who also appear to have upheld its sufficiency for matters pertaining to the faith, as Sola Scriptura means. St.Athanasius for example - “For although the sacred and inspired Scriptures are sufficient to declare the truth…” (Against the Heathen) (2)
The Catholic “Material sufficiency” view seems to come close to it, but still stresses the need for an infallible guide, the position of the majority of the various Protestant traditions stress this is not needed. With Material sufficiency, I always see the Catholic Church showing the sufficiency of scripture to the extent no external, unwritten apostolic tradition is needed, seems its all in scripture anyway? At least thats my perception, im always up for some discussion
As for the Acts 20 quote “It is better to give than recieve”. Firstly - Amen! Moving on; Does the Catholic Church know of any others not recorded in Scripture? Continuing, St.Luke in the opening of his Gospel - Luke 1:3-4
“It seemed good to me also, having diligently attained to all things from the beginning, to write to thee in order, most excellent Theophilus, That thou mayest know the verity of those words in which thou hast been instructed.” (Douay Rheims) (3)
Here St.Luke appears to suggest that with scripture, Christ’s words are solidified in a “veritable” or “truthful” way, that the truth may be reliably known in an unchanging way. This passage seems rather unnecessary to me unless by it he means before writing scripture they didnt have this truth with absolute certainty? It does i am happy to agree, show that St. Luke here can also be shown to affirm that before his Book they had the same truths, but as ive already stated, its now told to Theophilus that all is now solidified in writing, in an unchanging way.
As for the classic “how does a Protestant know which books belong in the bible?” - How does a Catholic? Obviously from the pronouncements of the Council of Trent. Before Trent? The councils of Rome and Carthage are often used here, but after a basic analysis, it is clear these councils were not ones regarded as infallible and ecumenical, rather, local ones.(4) In effect, no infallible pronouncement until Trent, after the Reformation was well under way. Rather the early Church recognised the books already authoritative in themselves, the Scriptures are authoritative not because the Church says what books they are, but because they are God-Breathed.(5)
That’s just some of my thoughts on the topic. Sola Scriptura does not mean I abandon tradition or church, rather Scripture is viewed by mainline Protestants as the ultimate authority over them.
Hope I have added to the discussion in a charitable way, thats how i would begin to defend SS. Forgive if I also am slow to respond to anything, I wanted to make a basic response but may not have the time to keep checking for responses.
In Christ, have a blessed day.
