Did Jesus really speak all the words the Gospels say He said?

A:

Probably not. The original known accounts of Jesus' mission are Mark's Gospel and the hypothetical 'Q' document so any Words, attributed to Jesus but not in these two books, are unlikely to have been spoken by Jesus.

Even Mark's author used poetic licence in attributing Words to Jesus. He says that Jesus's last Words on the cross were, "My God. My God. Why hast thou forsaken me?" But this was taken verbatim from Psalm 2:1, something a dyingman would not think to do.
