When Jesus corrected their mistaken view on the resurrection He did not do so with what would be clear texts from Scripture that they did not believe to be God’s word. Instead, He quoted from the books that they held to be Scripture (Mat 22:31-32)
It's also interesting to see that Jesus and the Apostles quote from the Greek Septuagint as the very words of God. They use the common version of the day...without referencing "the Hebrew really says..."
What does this mean for us today?
