Jesus and Blasphemy (Luke 22:65)

Luke writes: KAI hETERA POLLA BLASFHMOUNTES ELEGON EIS
AUTON. The NWT renders Lk. 22:65 "And they went on
saying many other things in blasphemy against him."
The NAB states: "they reviled him in saying many
other things against him."

Does this text indicate that Christ is Almighty God?
What about when Stephen the martyr was accused of
"speaking blasphemous sayings against Moses and God" (Acts 6:11?)
Why was Stephen charged with uttering blasphemous speech?
Were these charges merited? Lastly, notice that he spoke not only against
God, but also against Moses. Admittedly, as the
context shows, Moses equals Torah in this case. Yet there
was a sense in which ancient Judaism thought it was
possible to blaspheme representatives of God.

In Isa. 51:7 and Zeph. 2:8, we read of Israel having
blasphemy directed toward her by ungodly men. Are we to
conclude that such actions suggest the nation of
Israel was somehow equal to God? I don't think
any reader of this blog would draw that conclusion.
From this discussion, we learn that it is possible
to blaspheme an entity who is not ontologically
equal to Jehovah, the SUMMUS DEUS.
