No it is not, in fact the Canon of Scripture as being what was universally held to be the Canon was not formally defined till the 4th century. That is a fact.
Even ole James White, Mr. I have been debating for over 30 years finally conceding that sola scriptura was not even possible to bind everyone in the early Church before the 4th century since there was no agreed upon Canon of the Scripture.
Total 16th century Protestant novelty
Jesus had defined the OT and it does not include the books that Rome added at Trent.
We do have a good indication the canon was generally agreed upon by the end of the 2nd century. Some were in question due to authorship, but they were not rejected.
Paul's letters were already recognized as Scripture.
IIRC Athanasius was the first to provide a list of the books in the NT. However, this was recognizing what the church had already recognized. And IIRC, he excluded the books Rome has in the Apocrypha.
