Pope Shenouda III
As we mentioned  before, the salvation of the world from sins  needed an infinite  propitiation and none is Infinite except God alone.  Since the Lord  Jesus Christ offered the propitiation and completed it to  the uttermost  and redeemed all the people from every iniquity, saving  them eternally  from the curse of the Law, therefore, He is Infinite and  thence He is  God.
 The act of redemption is an excellent  proof confirming that  Christ is God because if He were not so, the  redemption would not  have been considered valid and would not have been  sufficient for the  salvation of the whole world from all their sins.
