“The Septuagint version of Scripture, from which Christ quoted, includes the Deuterocanonical books.”
Yes, and Jesus quoted none of them...
And if memory serves, Jesus never quoted from Ezra, Nehemiah, Esther, Ecclesiastes, Song of Solomon either.
So, I guess for you that must mean they’re not really scripture, right?
"you who have made all things by your Word." (Wisdom 9.1)
"In the beginning was the Word ... All things came to be through Him ... "(St. John 1.1,3)
