In Mark 14:55-65, Jesus is accused of blasphemy, which can be seen as a violation of the
First Commandment, not the Second.
Here's why:
* The First Commandment is "You shall have no other gods before me." Blasphemy, claiming to be God or acting as if one is God, would violate this commandment by placing oneself on the same level or above God.
* The Second Commandment is "You shall not make for yourself an image in the form of anything in heaven above or on the earth beneath or in the waters below. You shall not bow down to them or worship them; for I, the Lord your God, am a jealous God, punishing the children for the sin of the parents to the third and fourth generation of those who hate me, but showing love to a thousand generations of those who love me and keep my commandments." This commandment prohibits idolatry, the worship of graven images.
The charge against Jesus in Mark 14:58 was that he would destroy the temple that is made with hands, and in three days he would build another, made without hands. The high priest then asks Jesus in Mark 14:61, "Are you the Messiah, the Son of the Blessed One?"
Jesus replied in Mark 14:62, "I am," and then went on to say, "and you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven."
In Mark 14:64, the high priest says that Jesus is guilty of blasphemy.
By claiming to be the Messiah and the Son of God, and by stating that he would be seated at the right hand of God, Jesus was seen as making claims that were reserved for God alone. This was seen as blasphemy and a violation of the First Commandment.
