It is kind of hard to accept as a “definition” a string of qualifications that seems to attempt to hold two diametrically opposed principles at the same time?
How does this definition simply not boil down to the first sentence?
“Sola scriptura (Latin ablative, “by scripture alone”) is the doctrine that the Bible is the only infallible or inerrant authority for Christian faith, and that it contains all knowledge necessary for salvation and holiness. Consequently, Sola Scriptura demands that no doctrine is to be admitted or confessed that is not found directly or logically within Scripture.
“Sola Scriptura is not a denial of other authorities governing Christian life and devotion. Rather, it simply demands that all other authorities are subordinate to, and are to be corrected by, the written word of God.”
What is the point of all of the extra verbiage?
If “the Bible is the only authority” then playing lip service to other authorities only seems to confuse the issue.
You can’t claim the bible to be the “only” authority and then allow for other authority at the same time.
Finally, in the first sentence, I can accept inerrant, but a book cannot offer infallibility since it is incapable of making a judgment or pronouncement on any issue up for debate.
