Pope Shenouda III
God Alone Redeems and Saves the Human Race
  The Holy Bible explicitly testifies to this. It is written in the  Book of Psalms:  "None of them can by any means redeem his brother,  nor give to God a ransom for him...
 But God will redeem my soul from the power of the grave"   (Ps.  49:7,15). David the Prophet repeats the same meaning when he says:   "Bless the Lord, 0 my soul, bless His holy name!.. who forgives all   your iniquities... who redeems your life from destruction" (Ps.  103:1-4). And the Book of Isaiah the Prophet confirms this matter in  more than one testimony. It is written: "Thus  says the Lord, the King  of Israel, and his Redeemer, the Lord of  hosts: 'I am the First and I am  the Last; besides Me there is no God "  (Is. 44:6),  Therefore  the  Redeemer is This One God who is the Lord of hosts who is the First  and  the Last. Isaiah the Prophet repeats the same thing and says: "As for  our Redeemer, the Lord of hosts is His name, the Holy One of  Israel"  (Is. 47:4) and:  "Thus says the Lord, your Redeemer, the Holy One of  Israel 'I am the Lord  your God"'  (Is. 48:17). And God says:   "For I, the Lord your  God, will hold your right hand..' says the LORD and   your Redeemer, the Holy One of  Israel"  (Is. 41:13,14).
