There is a sort of logical error in using Bible scripture to argue sola scriptura is not Biblical.

Not at all.

If one claims that the Bible alone is the rule of faith, then the Bible itself should contain an assertion that it is itself the rule of faith.

One doesn't need to believe that the Bible is the only authority to believe that the Bible has authority.

This is similar to the Unitarian argument that Trinitarianism is false doctrine because the bible never uses the word Trinitarian.(The bible never uses the word Unitarian either.)

Poeple may follow what ever prophet/vicar/synod/temple etc but as for myself I will try to follow Testament of Jesus Christ.
