As I said, Jesus never claimed to be a "mediator" through any "ransom" he may have offered. Since the "ransom" doctrine is patently ridiculous, any claim that it is a "mediation" between God and man is also ridiculous.

Jesus never said He was the mediator because He didn't have to. The Jews of His day knew that the Messiah would be the mediator. Isaiah 9:6-7 verse 7 states that the messiah would firmly establish God's kingdom and sustain it by means of justice and by means of righteousness. God's justice demands and eye for an eye or a life for a life. In giving His perfect life, Jesus satisfied that justice so that we could stand in front of God, justified. He was the only corresponding ransom and therefore He is the only mediator.
