Third Wednesday of Advent
17 December 2025
O Sapientia – O Wisdom
Today, Advent turns a corner.
Up until now, the Church has kept our eyes lifted toward the horizon:
watching, waiting, listening for the Lord
who comes in glory.
Beginning today, the focus narrows.
We draw closer.
The mystery becomes more concrete.
We begin to walk the final steps that lead directly to Bethlehem.
To guide us through these days,
the Church gifts us with the ancient O Antiphons:
short prayers addressed directly to Christ under titles drawn from the Old Testament.
Each one reveals who the Messiah truly is
and asks Him to do something in us that only He can do.
They invite us to call on the Lord Jesus by a specific title,
and then ask him
under that title
to do something specific for us so
that we may become more like him.
These antiphons were already in use in the 700s in Rome
but may have their origin a few hundred years earlier than that. The Antiphons are prayed by the Church twice a day,
originally and principally during Vespers
before and after the Magnificat canticle
and then during the Alleluia verse
to prepare us for the Gospel at Mass.
The beautiful Advent hymn we sing
“O Come, O Come, Emmanuel,”
is based on the O Antiphons.
Today’s antiphon calls Him O Sapientia — O Wisdom.
Wisdom, in the Jewish tradition, is not abstract intelligence.
It is not information.
Wisdom is the ability to see reality as God sees it
and to live accordingly.
To be wise is to know where life truly comes from
and how God is patiently bringing it about.
That understanding of wisdom shapes how we hear today’s readings.
The Gospel today gives us the genealogy of Jesus.
At first glance, it can seem tedious:
a list of names,
unfamiliar and difficult to pronounce, as you heard me try.
But for Matthew’s Jewish audience,
this list would have been anything but boring.
It was an argument.
A proclamation.
A confession of faith.
By beginning with “Jesus Christ,
the son of David,
the son of Abraham,”
Matthew anchors Jesus firmly in Israel’s story.
Abraham represents promise.
David represents kingship.
Matthew is telling us from the first line:
this child is the fulfillment of everything God has been doing from the beginning.
Matthew doesn’t sanitize the story.
The genealogy includes broken kings, moral failures, exile, foreign women, scandal, and sin.
Tamar. Rahab. Ruth. Bathsheba.
Generations marked
not only by faithfulness,
but by collapse.
This is not a carefully curated résumé.
It is salvation history told honestly.
And that is where Wisdom appears.
God’s wisdom is not revealed by avoiding human weakness,
but by entering into it.
The genealogy shows us that God does not wait for a perfect family tree before acting.
He works through flawed people,
fractured decisions,
and painful consequences,
without being defeated by any of them.
That is the wisdom we call upon today.
The first reading from Genesis reinforces this.
Jacob speaks to his sons near the end of his life,
blessing them
and pointing toward the future of the tribes of Israel.
When he speaks of Judah,
he says that kingship will not depart from him.
This is not yet fulfilled.
Judah is not a king.
Israel has no throne yet.
But the promise is spoken anyway.
This is how biblical wisdom works.
God speaks meaning into history
before history can see how it will unfold.
Advent reminds us that God’s plan often becomes clear only in retrospect.
At the time, it looks slow. Confusing. Even disappointing.
But Wisdom is at work
—strongly and gently—
guiding everything toward fulfillment.
And that matters for us.
Many of us look at our own stories the way we look at the genealogy:
a mix of grace and regret,
faith and failure,
moments we would rather skip over.
The temptation is to believe that wisdom means starting over
with a cleaner version of ourselves.
But the Gospel tells us something better.
Wisdom does not erase our history.
It redeems it.
Jesus enters a real family line,
not an ideal one.
He allows Himself to be named among sinners
so that sinners might one day be named among the children of God.
As we begin this final stretch of Advent,
the Church teaches us how to pray wisely:
not asking God to remove us from our story,
but to enter it more deeply,
to shape it from within.
“O Wisdom…
come and teach us the way of prudence.”
Teach us to trust that God is still working,
even when the pattern is unclear.
Teach us to believe that grace is stronger than our failures.
Teach us to let Christ write the next chapter.
Because the Wisdom we await is not an idea.
He is a Person.
