“Such a standard shows unfamiliarity with the word of God. The Holy Spirit Himself testifies the scriptures are not the entirety of God’s word.”
No, but they are quite clearly enough to bring one to salvation and to prepare him fro a life of good works.

If the Creator of the Universe pronouncing the words "This is My Body" aren't enough "Scriptural support" for you, nothing would be.
