Sola Scriptura represents the dissolution of authority into individualism.
Anytime someone claims something, you can square that with (your reading of) Scriptura.
And if it does not fit, it is not Sola. A-HA! Gotcha, Pastor! Scholarship will not save’ya. Charisma will not save’ya. Erudition and charisma is no substitute for legitimate authority.
Sola Scriptura is the single grand transfer of authority from the legitimate Church to the individual (ab)using it.
John Lennon, you are so very outdated. „Power to the people” was invented four hundred (400) years before you, in the melting pot of the Reformation.
Power (to interpret the scripture) to the people! And the people got power indeed.
Now you got it! Now handle it!
