How about the “scriptures” left out by the Council of Laodicea 300 year after the resurrection when the Bible was assembled ? Are the “God Breathed”? What is a “scripture” ?
“What is a scripture ?”
In that verse, it means the Torah and Tanakh of the Hebrews. The word used translated literally as “writings”, with the implied sense of “holy writings”, and those were the only holy writings that would have been recognized by the people being spoken to.
There were none that were left out. The vast majority of the canon was already decided before this council. This council confirmed what was already known by the church.
