Third Friday of Advent
19 December 2025
O Radix Jesse – O Root of Jesse
As we continue the second part of Advent,
the Church teaches us
not only who the Messiah is,
but where He comes from.
Each O Antiphon draws us deeper into Israel’s story,
naming Christ with titles that reveal how God has been working patiently, quietly, and faithfully across generations.
Today we call out to Christ as
O Radix Jesse — O Root of Jesse.
A root is hidden.
It works underground.
It grows silently.
And yet everything visible depends on it.
In the Jewish imagination,
the “root of Jesse” refers to the royal line of David.
Jesse was David’s father.
To speak of a root rather than a branch is to acknowledge something deeper than kingship or power:
God’s promise survives
even when the visible signs of that promise seem to have failed.
By the time of Jesus,
the house of David looked finished.
There was no Davidic king on the throne.
Israel was occupied.
Rome ruled and dominated.
The promises seemed buried.
But roots do not die simply because they are unseen.
That truth prepares us to hear today’s readings.
The first reading from the Book of Judges takes us back into a recurring biblical pattern:
barrenness.
Manoah’s wife is unable to conceive.
In the ancient world,
this was not only painful personally
but devastating socially.
Barrenness often symbolized hopelessness…
a future cut off.
And yet, once again,
God enters precisely there.
An angel announces that the barren woman will bear a son
— Samson —
one who will begin to deliver Israel.
The key word is begin.
Samson is not the final answer.
He is not the fulfillment.
But he is part of the root system God is growing beneath Israel’s history.
For Israel,
this story would have sounded familiar.
God brings life where there is none.
He works through weakness.
He plants hope where nothing seems possible.
This is how roots grow.
The Gospel continues the same theme,
but deepens it.
Zechariah and Elizabeth are righteous, faithful, and childless. Their barrenness is not a punishment.
It is a mystery.
And into that mystery,
God speaks again,
announcing the birth of John the Baptist.
But unlike Manoah’s wife,
Zechariah hesitates.
He asks for proof.
And in response,
he is struck silent.
This silence is not punishment in the crude sense.
It is formation.
Zechariah must learn to wait.
To trust.
To let God act without commentary.
In Jewish tradition,
silence is often associated with wisdom and reverence. Zechariah’s muteness becomes a space where God’s promise can grow without interference.
The root is growing,
quietly, invisibly
even when words fail.
The O Antiphon today addresses Christ as the Root who stands as a sign to the nations,
before whom kings fall silent.
That image is powerful.
It reminds us that God’s deepest work is often
hidden, unnoticed, and slow.
Advent teaches us not to confuse delay with absence,
which is where almost everyone goes to in their mind.
Just because God’s promises are not visible
does not mean they are not alive.
For many of us,
this is where Advent becomes personal.
We know what it is to feel barren:
- in prayer
- in hope
- in family situations
- in the Church
- in our culture
The Scriptures answer gently but firmly: yes.
Because God does not start over from scratch.
He works through roots,
promises planted long ago,
still alive beneath the surface.
Christ does not appear suddenly,
disconnected from history.
He rises from a root nourished by
faith, suffering, waiting, and trust.
When we pray,
“O Root of Jesse, come,”
we are asking Christ to do something very specific:
- to restore hope where it seems lost
- to bring life where we see only barrenness
- to strengthen faith when waiting feels long
first in us,
and then through us.
Advent reminds us that salvation does not burst forth fully formed. It grows.
Slowly. Faithfully. Underground.
The Root of Jesse is already at work.
In history. In the Church. In our lives.
Even now, something is growing.
And what God has planted, He will bring to life.
