An important passage describes Jesus’ trial before the Jewish leadership (Mark 14:60-64). They asked him point blank, “are you Messiah, the Son of the blessed one?” Jesus response is powerful: “I am,” said Jesus. “And you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven.” Now there is a lot here. But the most important point is this, Jesus is quoting Daniel 7:13-14 and refers to himself as the “Son of Man.” If you go back and read the Daniel passage you will see that the Son of Man is in the presence of the Ancient of Days (God himself) and is given authority by him (cf. Ps 110).
The Jewish leadership, who knew the Hebrew Scriptures well, got the message loud and clear responding that this was blasphemy and that Jesus deserved to die for claiming to be God (Mark 14:63-64). People don’t get crucified for spouting off moral platitudes or loving everybody (though Jesus certainly loved people and was not promoting immorality). Something more is needed. No one denies that Jesus died by roman crucifixion. So why was he crucified?
This passage is your answer. The Jewish leadership clearly understood who Jesus claimed to be—God—and they had him crucified because of it. The early church did not turn Jesus into a God 400 years later at a church council as many today are saying. Jesus was so clear on this point, that it got him crucified.
