Genesis 22:15Meaning & Commentary from the Church Fathers

He reiterates His promises, declaring: “And the angel of the Lord called to Abraham a second time from heaven, and said: ‘I swear by me, saith the Lord, that because thou hast done this work, and hast not spared thy son, thy only son, I will bless thee, and multiply thy seed as the stars of heaven, and as the sand upon the seashore; and thy seed shall possess the cities of their enemies; and all the nations of the earth shall be blessed in thy seed, because thou hast obeyed my voice.’” The Lord emphasizes Abraham's obedience, saying, “By Me I swear, saith the Lord,” assuring that His promises will be faithfully fulfilled. Just as people reinforce their commitments with oaths to provide assurance to others, the Lord adopts this human practice, affirming, “By Me I swear, saith the Lord, that since thou hast done this work, and hast not spared thy son, thy only son, for Me.”

Consider the Lord’s empathy in His words: “Thou hast not spared thy son, thy only son, for Me,” while He Himself rewards the son with life. Do not simply focus on the conclusion of the event, dear ones; instead, reflect on the heartfelt willingness with which the forefather obeyed without hesitation. The sincere commitment of Abraham was such that he had already raised the knife, poised to offer the sacrifice. Thus, the Lord, acknowledging the intent as if the sacrifice had truly taken place, commends the righteous man, stating, “Thou hast not spared thy son, thy only son, for Me.” Yet, because you did not withhold him for My command, I have spared him for your faithfulness.

This blessing is greater than the previous ones, for while God assured Abraham that his descendants would flourish, in this case, He declares: "And in your seed shall all the nations of the earth be blessed because you have obeyed My voice" (Gen. 22:18). Therefore, let us heed the voice of our God and follow His commands if we seek to earn His favor.

During the services of Holy Saturday, we remember the suffering, death, burial, and resurrection of Christ the Saviour. It becomes clear then why in one of these services, Vespers, the reading of the account of Isaac's sacrifice is included. This event serves as a foreshadowing of the suffering, death, and resurrection of Christ. Here are the parallels between the image and the events they reflect: (1) Just as Abraham, out of love for God, was willing to sacrifice his beloved son Isaac, the Father did not withhold His only begotten Son, but gave Him up for all of us (John 3:16, Romans 8:32). (2) Isaac journeys away from his home to the place that God designated for sacrifice, while Christ was called to leave Jerusalem and suffer outside its gates (Hebrews 13:11). (3) Isaac left behind his servants as he ascended the mountain for his slaying; similarly, Jesus was forsaken by His disciples as He went up the mount of propitiation. (4) Both Moriah, where Isaac's altar was prepared, and Golgotha, where Christ was offered, are part of the hills surrounding Jerusalem. (5) Isaac carries the wood for his own sacrifice, while Jesus bears His cross before being lifted up on it. (6) Isaac willingly submits to his father for the sacrifice; likewise, Jesus fully complies with His Father’s will through His suffering, remaining obedient unto death, even death on a cross (Philippians 3:8). (7) Isaac is condemned without guilt; Jesus, in contrast, endures suffering and death for the transgressions of others despite being sinless and holy. (8) Isaac, who is spared from death, prefigures Christ, who triumphed over the bonds of death in His resurrection. (9) While Isaac did not genuinely suffer but allowed for the ram, Jesus suffered only in His humanity, paralleling the ram’s symbolism. (10) On the third day after the sacrifice, Isaac’s mother sees him alive; likewise, after three days, the Church witnesses the resurrection of Christ, as Chrysostom states. (11) The sacrifice of Isaac brought abundant blessings upon all of Abraham's descendants, just as the sacrifice of Jesus Christ brings countless blessings to all who believe in Him, regardless of their lineage or tribe.
