In the name of the Father, the Son, and the Holy Spirit, one God. Amen.
This lesson follows the teaching of St. Athanasius the Apostolic, 20th Pope of Alexandria, in his foundational work On the Incarnation. In it, he answers the most profound question in all of theology: Why did God become man? The answer begins not with the cross, but with creation itself.
Created in the Image and Likeness
In the book of Genesis, God said:
"Let Us make man in Our image, according to Our likeness." - Genesis 1:26
But notice something remarkable. When God actually created man, the Scripture says:
"So God created man in His own image." - Genesis 1:27
The word "likeness" disappears. Why? Because God creates us in His image - giving us intellect, infinite ambition, and life itself - and then leaves us to grow into His likeness through our own free will. The likeness is the destination: kindness, righteousness, doing good. The image is the starting point. God gave us the image as a gift; the likeness is what we are meant to become.
St. Athanasius the Apostolic wrote:
"God created man for incorruption and made him in His own image."
And we pray in the Basilian Liturgy:
"God the great and eternal, who formed man in incorruption."
This means that humanity received two blessings from God: first, existence from nothing - we did not have to exist, but God called us into being out of love. Second, He gave us the gift of eternal life through the divine image within us. Without the image, there is no reason for eternal life. Think of it this way: a page from the Bible and a page from a newspaper are both paper. But the Bible page carries the word of God, and therefore you treat it with reverence. Remove the word, and it is just paper. In the same way, without God's image, a human being has no basis for immortality.
The Fall and Death
But what happened? Man sinned. And when man sinned, the image of God within him became distorted.
God had warned:
"On the day that you eat of it, you shall surely die." - Genesis 2:17
This was not arbitrary punishment. It was a statement of reality. When God's image ceases to function in a person, death is the natural consequence - because life itself comes from God. The fall came through pride. The serpent said, "You will be like God" - and man reached for divinity on his own terms rather than receiving it as a gift through communion with God.
Think of a refrigerator. When it is connected to electricity, it keeps things cold. Disconnect it, and everything inside decays. The refrigerator did not break - it was separated from its source of power. In the same way, man was not destroyed by some external punishment. He was disconnected from God, and disconnection from God is the very definition of death.
St. Paul put it plainly:
"The wages of sin is death." - Romans 6:23
Death is not God's revenge. It is the inevitable result of separation from the Source of life.
Why Was the Incarnation Necessary?
St. Athanasius the Apostolic, in On the Incarnation, lays out six devastating reasons why the Incarnation was not optional but absolutely necessary. This is not mere theology - it is the logic of God's own character:
1. It Was Impossible to Escape the Judgment of the Law
God had decreed that the consequence of sin is death. This is not a suggestion. It is the law of the universe established by God Himself. If this judgment could simply be set aside, then God's word means nothing, and the entire moral order collapses. The law must be fulfilled.
2. It Was Not Appropriate for God to Refrain from Executing the Death Judgment
If God said, "On the day you eat of it, you shall surely die," and then simply chose not to enforce it - God becomes a liar. And if God is a liar, then nothing He says can be trusted, and the entire foundation of faith collapses. God cannot contradict Himself.
3. It Was Not Fitting for Rational Creation to Perish Due to Satan's Deception
Humanity did not invent sin independently. We were deceived by Satan. For rational beings, created with intelligence and purpose, to be permanently destroyed because of another creature's deception - this does not fit the wisdom of God. It would mean Satan wins, and God's highest earthly creation is lost forever through trickery.
4. It Was Inappropriate for Humanity in God's Image to Continue Deteriorating
If God created humanity in His own image and then allowed that image to decay into nothingness, it would reflect poorly on God Himself. An artist who watches his masterpiece being destroyed and does nothing is called negligent. How much more would it be for God to watch His image-bearers disintegrate?
5. If God Neglected His Creation, It Would Imply Weakness
If God saw humanity falling into corruption and did not act, one might conclude that God lacked the power to save. But God is almighty. Inaction in the face of the destruction of His creation would suggest either weakness or indifference - and God is neither weak nor indifferent.
6. Allowing Corruption to Continue Would Contradict God's Goodness
God is good by nature. His goodness is not passive - it is active and creative. To allow the corruption of His creation to stand unchallenged would be a denial of His own goodness. A good God must act to restore what has been corrupted.
These six points create an inescapable conclusion: God had to act. And the only One who could act effectively was the Word of God Himself.
What Only the Word of God Could Do
St. Athanasius the Apostolic shows that the Word of God - the Second Person of the Holy Trinity - was uniquely qualified to accomplish what no angel, no prophet, and no mere creature could do:
1. Pay the Debt for Everyone
Humanity owed a debt of death. Every person, without exception, was under this sentence. No individual human could pay the debt for all of humanity - each person owed his own death. But the Word of God, by taking on a human body and offering it on the cross, paid the debt for everyone at once. One death for all.
2. Transform Corruption into Incorruption
Imagine a body with necrotic tissue - dead, decaying flesh. A doctor cannot simply forgive the necrosis. He must cut it out and replace it with living tissue. In the same way, humanity's nature had become corrupted - not just sinful in action, but corrupted in essence. The Word of God entered human nature and transformed it from the inside, turning corruption into incorruption.
3. Recreate Humanity in God's Image
The image of God in humanity was distorted beyond human repair. The Word of God, who is Himself the original Image, came to recreate that image in us. This is what happens in baptism - the new birth. We are not merely forgiven; we are remade.
4. Make the Mortal Immortal
Death had become the defining reality of human existence. The Word of God, by uniting immortal divinity with mortal humanity in His own Person, broke the power of death from within. He made it possible for mortal beings to become immortal - not by their own power, but by union with Him.
5. Teach Humanity About the Father
Humanity had fallen so far that it no longer knew God. Idolatry had spread everywhere. People worshipped the sun, the stars, animals, and images made by their own hands. The Word of God became visible so that through His visible works, people could know the invisible Father. He came to destroy idolatry by revealing the true God in a way humanity could understand - through a human life.
Can Repentance Alone Save?
This is one of the most important questions St. Athanasius the Apostolic addresses. Many people assume that if humanity simply repented, God could forgive and everything would be resolved. But St. Athanasius makes a crucial distinction:
"Repentance cannot change human nature fallen into corruption. It can only stop further sins."
Think of drug addiction. A person addicted to a substance can decide to stop using it - that is repentance. But the damage already done to his body, his brain, his organs - that requires healing. Stopping the drug does not undo the harm. Repentance stops the sinning, but it cannot reverse the corruption that sin has already caused in human nature.
Consider this analogy: a child has a terrible infection. She is dying. Her father finds her and says, "I forgive you for playing in the dirt." Does the forgiveness heal the infection? Of course not. What the child needs is not just forgiveness - she needs medicine. She needs iodine on the wound, antibiotics in her blood, a doctor's skilled hands. Forgiveness alone does not heal a dying child.
So the question becomes: should God forgive, or should God heal? The answer of the Incarnation is: both. But healing requires more than a decree. Once humanity existed and had become corrupted, God could not simply issue a command from heaven and undo the corruption. He had to come Himself, enter human nature, and heal it from within.
Could God have simply issued a decree? St. Athanasius says no - because the problem was not merely legal. It was ontological. Human nature itself was corrupted. You cannot fix a broken nature with a spoken word from a distance. The doctor must come to the patient. The Word became flesh.
Why the Son Specifically?
Why was it the Son - the Second Person of the Trinity - who became incarnate, rather than the Father or the Holy Spirit?
The answer lies in the concept of the image. St. Paul writes:
"He is the image of the invisible God, the firstborn over all creation." - Colossians 1:15
"Who, being in the form of God, did not consider it robbery to be equal with God." - Philippians 2:6
"Who being the brightness of His glory and the express image of His person." - Hebrews 1:3
Christ is not merely an image of God - He is THE Image. We are made in His image - like copies of the original. When a copy is damaged, you need the original to restore it. You cannot restore a copy from another copy.
St. Athanasius the Apostolic gives a beautiful parable: imagine a king commissions an artist to paint his portrait on a wooden panel. Over time, an enemy comes and disfigures the portrait - scratching, staining, and distorting the image until it is unrecognizable. What must happen for the portrait to be restored? The artist must come back. But the artist needs the king's son - the living likeness of the king - to sit before him as the model. Without the original, the portrait cannot be repainted.
Christ is the Original Image. The Holy Spirit is the Divine Artist who restores God's image in us. And we are the disfigured icons being restored. This is why it had to be the Son - because He is the Original after which we were made. To restore the copy, the Original Himself had to come.
Christ's Death and Resurrection
Here we arrive at the greatest paradox in all of existence. Christ is Life itself. He is the Word through whom all things were made. He is the source of all life in the universe. And yet - He had to die.
St. Athanasius calls this the equivalent of "dried water" - a contradiction in terms. How can Life die? And yet this is precisely what happened, and it had to happen.
Three Reasons Christ Should Not Have Died
Consider that there were three reasons why death had no rightful claim on Christ:
-
He did not inherit the judgment. The sentence of death passed to all of Adam's descendants through natural generation. But Christ was not born of a man and a woman - He was born of the Virgin Mary by the Holy Spirit. He was not under Adam's sentence.
-
He committed no sin. Death is the wages of sin - but Christ never sinned. Not once. Not in thought, word, or deed. Death had no legal basis to claim Him.
-
His body was united with immortal divinity. The body of Christ was not an ordinary human body left to its own nature. It was united - without separation, without confusion, without alteration, without mixing - with the divine nature of the eternal Word. Divinity cannot die.
He Died Willingly
And yet He died. Why? Because He chose to. Scripture says:
"It was impossible for death to hold Him." - Acts 2:24 (NKJV paraphrase)
Death could not hold Him, but He walked into it willingly. He laid down His life - no one took it from Him.
What Happened When Life Entered Death
Think of a wildfire raging out of control. Firefighters sometimes light a controlled burn - they set fire to the fuel in the wildfire's path before it arrives. When the wildfire reaches that area, there is nothing left to burn. The fire exhausts itself and dies. This is what Christ did to death. Death is a fire that consumes every human being. But when death reached the body of Christ - the body of Life Himself - it had nothing to consume. Death exhausted itself in Christ and was destroyed.
Or think of it as a debt. Imagine someone owed an enormous debt that could never be repaid. Then a wealthy benefactor comes, goes to the creditor, and presents documents proving the debt has been paid in full. The case is closed. The debtor is free. Christ presented His own death as the payment for humanity's debt, and the case was closed forever.
Or consider a death certificate. When someone dies, a death certificate is issued, and no further legal proceedings can be brought against that person. Christ's death was humanity's death certificate - the sentence was executed, death was satisfied, and no further claim could be made.
Legal and Healing - Not One or the Other
This is where St. Athanasius the Apostolic's genius shines. In Western theology, the emphasis has traditionally been on the judicial perspective - Christ paid the legal debt of sin. In Eastern theology, the emphasis has traditionally been on the healing perspective - Christ healed corrupted human nature. But St. Athanasius, writing centuries before this divide, holds both together seamlessly.
The cross is both a courtroom and a hospital. Christ both paid the debt and healed the disease. He satisfied divine justice and transformed human nature. These are not competing explanations - they are two dimensions of the same act. Any theology that holds only one and rejects the other is incomplete.
How Could the Immortal Die?
One more question remains: how could the immortal Word actually experience death? St. Athanasius uses a vivid image: imagine squeezing water from a sponge. The sponge absorbs and holds the water, and when squeezed, the water flows out. The immortal Word united Himself with a mortal human body. In that body, through the mystery of the union, the Immortal One was able to taste death for every person.
This is why our Lord Jesus said:
"I am the bread of life. He who comes to Me shall never hunger, and he who believes in Me shall never thirst." - John 6:35
And:
"Unless you eat the flesh of the Son of Man and drink His blood, you have no life in you." - John 6:53
The Holy Eucharist is the medicine of immortality. In the Eucharist, we receive the Body and Blood of the One who conquered death - and His immortal life enters our mortal bodies, healing us from the inside, transforming corruption into incorruption, one communion at a time.
Conclusion
The Incarnation of the Word is not a secondary doctrine. It is the center of everything. Without it, there is no salvation - because repentance alone cannot heal corrupted nature, forgiveness alone cannot restore the divine image, and no decree from heaven can transform mortality into immortality. Only the Word of God - the Original Image, the Source of Life, the eternal Son - could accomplish what needed to be done.
He came because the law demanded it. He came because God's truthfulness required it. He came because His wisdom would not allow rational creation to be permanently deceived. He came because His image in us could not be left to rot. He came because He is almighty and could not ignore His creation. He came because He is good, and goodness acts.
And when He came, He paid the debt, healed the disease, restored the image, conquered death, and revealed the Father. He did it all - not from a distance, but by entering our nature, wearing our flesh, and dying our death.
May we receive His Body and Blood with trembling and thanksgiving, knowing that in every Eucharist, the medicine of immortality enters us, and the Divine Artist continues to restore the image of God within us.
"And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth." - John 1:14
