Is Sola Scriptura Biblical?

Sola Scriptura (by scripture alone): the belief that all truth necessary for our salvation and spiritual life is taught either explicitly or implicitly in Scripture.

‭‭2 Timothy ‭3‬:‭13-17 ‭NIV‬‬

while evildoers and impostors will go from bad to worse, deceiving and being deceived. But as for you, continue in what you have learned and have become convinced of, because you know those from whom you learned it, and how from infancy you have known the Holy Scriptures, which are able to make you wise for salvation through faith in Christ Jesus. All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the servant of God[a] may be thoroughly equipped for every good work.

All scripture is God-breathed (infallible)... are the writings of the early church Fathers "God-breathed"?
‭‭2 Thessalonians ‭2:15 ‭NRSVCE

So then, brothers and sisters, stand firm and hold fast to the traditions that you were taught by us, either by word of mouth or by our letter.

Were the traditions practiced by Paul and the early churches the same as the traditions being taught by Catholics?
