AN EXPLANATION ON THE MYSTERY OF THE INCARNATION FOR ELAINE

The Mystery of the Incarnation is the Center of the Christian Faith, the Hinge of Our Covenantal Theology, a Revealed and Incomprehensible Activity of the Holy Trinity, and the Economy of Salvation that Transforms the Whole Universe

Dear Daughter in Christ, 

Your question about how you can explain the Incarnation to your Muslim friends touches on the very core of the Christian Faith. “How is it that Christ is fully God and fully Man?” is the question over which the Ancient Church labored, and the Apostles preached, the Martyrs suffered, and the Fathers contended with tears and precision in the Holy Ecumenical Councils. Indeed, it is no exaggeration to say that the entire life of the whole Church gathered itself around this single confession: Who is Jesus Christ?

And the Church, receiving rather than inventing, speaks with a voice at once reverent and exact:

“I believe… in one Lord Jesus Christ,

the Only-begotten Son of God…

God of God, Light of Light, Very God of Very God…

Who for us men and for our salvation came down from heaven,

and was incarnate… and was made man.”

So confesses the Nicene-Constantinopolitan Creed, that luminous boundary within which all faithful speech must dwell. And the holy Council of Chalcedon, refining this confession against error, declares that the one Lord Jesus Christ is...

“perfect in Godhead and perfect in manhood… truly God and truly man… in two natures, without confusion, without change, without division, without separation.”

Here we stand already at the threshold of mystery: not a confusion of thought, but a precision guarding what exceeds thought.

For when we say that Christ is “fully God,” we do not speak metaphorically, nor ascribing to Him a borrowed divinity. We confess with the Evangelist:

“In the beginning was the Word, and the Word was with God, and the Word was God.” (John 1:1)

He is the eternal Logos, not a creature elevated, nor a prophet adorned, but God Himself, Light from Light, sharing the very being of the Father. As St. Athanasius, that great defender of the Faith, wrote with uncompromising clarity, “He became man that we might become god.” For only God can unite man to God; only He who is Life by nature can restore life to the dying.

Yet with equal force, and here lies the scandal to many minds, we confess that this same Word “was made flesh, and dwelt among us” (John 1:14). Not in semblance, nor in illusion, but in truth. He took upon Himself all that belongs to our humanity: body and mind, will and affection, growth and weariness, suffering and even death itself. The Epistle to the Hebrews presses this point with pastoral urgency:

“He was in all points tempted like as we are, yet without sin.” (Hebrews 4:15)

And thus St. Gregory the Theologian gives us a rule as sharp as any blade: “What is not assumed is not healed.” If Christ were not fully man, then some portion of our humanity would remain forever outside the reach of redemption.

We are therefore compelled by Scripture, by the Fathers, by the very logic of salvation, to hold together what seems, at first glance, impossible: that Christ is wholly God and wholly man. But the Church does not say that He is two beings, nor that He is divided within Himself. Rather, she speaks of one Person, one Hypostasis, the eternal Son, who has taken a human nature into His divine life.

The Fathers, seeking language adequate to this wonder, spoke of the union as one “without confusion and without division.” They likened it, at times, to iron placed in the fire: the iron glows with the energy of the flame, yet remains truly iron; the fire penetrates it, yet remains fire. So in Christ, the divine does not overwhelm the human, nor does the human diminish the divine; both remain what they are, yet belong wholly to the one Lord Jesus Christ.

This is what the Church calls the Hypostatic Union, which is not a theory to be solved through speculation, but a reality to be confessed and adored by the whole Church as something revealed by the Holy Spirit and faithfully kept in Apostolic Succession.

Your question, however, presses further, and rightly so: how did this union appear in the life of Christ as He walked among us? For the Scriptures themselves present us with a striking duality. On the one hand, we are told that He “knew all men… and needed not that any should testify of man: for he knew what was in man” (John 2:24–25). On the other, we read that “Jesus increased in wisdom and stature” (Luke 2:52), and even that “of that day and hour knoweth no man… neither the Son” (Mark 13:32).

Here again the Church refuses both simplification and contradiction. She teaches that Christ possesses two modes of operation, according to His two natures. As God, He knows all things eternally and without limitation. As man, He truly lives within the conditions of human existence. He learned, grew, and experienced time and limitation. Yet these are not the acts of two persons, but of one Person acting through both natures.

St. Maximus the Confessor, whose subtlety is matched only by his fidelity, explains that each nature operates “according to its own mode,” yet in perfect communion within the one Christ, so much so that their duality is sometimes invisible, God's will seamlessly working through both natures. The divine does not abolish the human; the human does not constrain the divine. Rather, the Incarnation reveals, for the first time, what humanity is meant to be when united perfectly to God, the potential that Adam denied and that was fully realized in Christ. 

Thus, Christ may hunger and yet feed thousands; He may weep at the tomb of Lazarus and yet call the dead to life; He may grow weary upon the road and yet uphold the universe by the word of His power. These are not contradictions, nor theatrical gestures, but the living expression of one divine Person in the fullness of both natures.

And this brings us, finally, to why all of this matters. For the doctrine is not an abstract puzzle, nor an exercise in metaphysical subtlety. It is the very ground of our salvation. If Christ were not truly God, He could not save; if He were not truly man, He could not heal. But being both, He becomes, as the Apostle says,

“the one mediator between God and men, the man Christ Jesus.” (1 Timothy 2:5)

He does not merely bridge the gap between God and man: He is that bridge, the living union of Creator and creature. As St. Irenaeus declares with luminous simplicity, “He became what we are, that He might bring us to be even what He is.” And C.S. Lewis, in a later age, echoes the same truth: “The Son of God became a man to enable men to become sons of God.”

We must therefore resist the temptation to imagine that this mystery can be fully resolved within the limits of human reasoning. It is not irrational, but it is, as the Fathers would say, beyond human reason, drawing the mind upward rather than closing it in upon itself. Gerard Manley Hopkins, an English poet and Catholic priest, catching something of this vision, writes that “the world is charged with the grandeur of God.” In Christ, that grandeur is not merely perceived. God is made flesh, touched, heard, crucified, and risen.

So, take heart dear daughter. You did not fail in your conversation by being unable to express the profound mystery of God made Man; you arrived at the edge of the Church’s deepest confession. There is no shame in pausing before such a mystery, because such pause and silence is the beginning of all wisdom. We speak of something that even the Angels cannot understand. 

For in the end, we do not solve Christ; we worship Him. We confess with the Apostle:

“Great is the mystery of godliness: God was manifest in the flesh.” (1 Timothy 3:16)

And in that confession, we find not confusion, but eternal union with God through the shared life of the Holy Trinity.

May our Lord Jesus Christ, very God and very Man, grant you both clarity and wonder, firmness in truth and gentleness in speech, that you may bear witness to Him with both mind and heart, to share the depths of God's revelation to humankind through the impartation of the Holy Spirit!

A Meditation on the Incarnation

O Christ, Eternal Word of the Father,

Silence before all worlds,

Brightness hidden within uncreated Light,

Thou who didst enter the frailty of our flesh

without ceasing to fill heaven and earth:

grant unto us hearts that do not merely analyze Thy mystery,

but stand before it in reverent wonder.

Teach us to behold Thee rightly:

not as an idea fashioned by human reasoning,

nor as a distant prophet clothed only in symbols,

but as the Living God made visible,

the Infinite dwelling among the finite,

the Holy One who entered hunger, sorrow, weariness, tears, and death,

that death itself might be shattered from within.

Thou hast united in Thyself

what our violence had torn apart:

God and man, eternity and time,

spirit and dust, glory and suffering.

And in Thy Incarnation,

the universe is no longer abandoned to meaninglessness,

for matter itself has been touched by fire divine.

Grant us therefore the mind of the Fathers:

precise in truth,

humble before mystery,

fearless in confession,

and filled with love.

Preserve us from the arrogance that seeks to reduce Thee

to the scale of our own understanding.

For Thou art not conquered by argument,

nor contained within the boundaries of language.

Thou art the abyss of divine mercy

into which prophets gazed,

martyrs descended,

and saints were transformed.

When doubts arise within us,

let them become doors into deeper contemplation.

When the mystery seems too high,

let us remember that love itself surpasses comprehension.

And when we speak of Thee before the world,

grant that our words may carry not merely information,

but the fragrance of holiness,

the peace of truth,

and the radiance of Thy presence.

For Thou didst not become man

so that we might win debates,

but so that humanity might again partake of divine life;

that the lost might be found,

the fractured healed,

the fearful made bold,

and the dead raised incorruptible.

O Jesus Christ,

Very God and Very Man,

Image of the invisible Father,

Firstborn from the dead,

and Bridegroom of redeemed creation:

draw us ever deeper into Thy life,

until every thought becomes prayer,

every breath becomes thanksgiving,

every wound is transfigured by Thy love,

and every fragment of our fallen nature made radiant by Thy life.

For unto Thee are due all glory, wisdom, worship, and adoration,

with the Father who is without beginning,

and Thy All-Holy, Good, and Life-giving Spirit,

now and ever, and unto ages of ages. Amen.
