This reading seems jarring,
unsettling—
Frankly,
it feels as if it belongs in our headlines,
not our Gospel.
In fact,
given the ugly divisions of our world,
I am not sure I even want to read today’s gospel,
much less preach it.
Isn’t there enough pain?
Enough confrontation?
Enough division?
Enough fire?
Don’t we look to Jesus, and religion, and the Church
to be a balm and a comfort?
To be a bandage for our wounds
and safe harbor from our fears?
Yet, Jesus declares:
"I have come to set the earth on fire,
and how I wish it were already blazing!"
He also states,
that contrary to what we might believe,
He has come NOT to bring peace,
but division.
This is a message
that ready or not,
invites a closer look,
even if we have to peek between our fingers
to do it.
It helps to remember that
in the Bible,
fire can be a symbol of destruction and pain.
But it can also be a symbol of purification,
passion,
presence--
Fire is a Sign Post,
marking the holy ground of God.
Moses encountered Yahweh in the burning bush.
Elijah was swept up into heaven in a chariot of fire.
The disciples received the Holy Spirit
with tongues of fire dancing on their heads.
When Jesus speaks of setting the earth on fire,
I don’t think he is talking about destruction
simply for the sake of tearing down
and burning up.
Jesus doesn’t want to break things,
burn things,
destroy things
just because he can.
The fire Jesus wants to ignite
is the fire of transformation
fueled by the flames of change.
He is calling down the fire of purification
and setting up a forge,
to temper steel,
not hurling a Molotov cocktail
or gleefully punishing the damned.
Jesus wants to strike a match
to illuminate God’s active presence in the world.
Matt Skinner, a professor of New Testament says,
“Bad popular theology has done so much
to train congregations to hear Luke 12:49
as a description of a God with an itchy trigger finger
who just can’t wait to smoke some sinners.
As a result, people duck their heads
and wait until Jesus calms down
and a nicer passage comes along.
Isn’t the Parable of the Prodigal Son coming soon?”
Ducking our heads and hoping for the best
at first glance,
seems like a pretty legit reaction,
because even the most learned theologians struggle
with these passages,
and preachers--
preachers sit in their office on Tuesday afternoon
read about fire,
and destruction,
and division
and think….
“Maybe it’s a good Sunday to preach about
Ordinary Time,
or Going Back to School
or Vocations to the Priesthood and Religious life.”
But duck and weave how we will,
this Sunday, we are given fire.
And the language and images make us
Uncomfortable.
Perhaps especially those who are
comfortable.
In charge.
Certain of their position in the world.
For those of us who are privileged,
these images can be disturbing
and even frightening.
They signal a quantum change
that will demand a response.
This agenda of Jesus will overturn priorities,
values
choices.
In a conflagration, few things survive.
Precious artifacts,
beloved treasures,
even people can be lost.
But what if we view this passage
from another angle—
from the perspective of those who suffer;
from the point of view of the enslaved,
the poor,
the migrants who hunger for home,
the youth who struggle with identity--
From that perspective,
we might see this purging fire as something
necessary—and even welcome.
How much in our systems
and principalities
and ways of doing business must be destroyed
in order to rebuild them in justice?
How much of our social order and economic system
must be purified,
tempered,
forged into something stronger and truer
in order to create a world of peace?
Are we willing to be set on fire
by the love of Christ?
Are we willing to embrace
the change of heart and mind
He calls us to?
Are we ready, even if it means facing difficulty,
suffering, or division?
This fire of Christ is not a comfortable thing.
It requires a bold and courageous response.
This peace of Christ is not a simple thing.
It requires wisdom and patience and love.
For peace is more than avoiding conflict
or joining our hands in song.
The Peace of Christ disrupts sin,
challenges injustice,
calls us to radical hospitality.
The justice of Christ
may put us at odds with family and friends.
It may invade our comfortable hideouts.
It may overturn our routine
and dig ruts in our well-worn paths.
Following Christ into the maelstrom
will require clear eyes and firm purpose.
But Jesus wants to call us –
not to division
but to unity.
These divisions He speaks of are not of His making,
but ours.
The Gospel doesn’t force division,
but in choosing peace over privilege;
in siding with justice over comfort;
in practicing hospitality rather than exclusion
we will inevitably create a dividing line
between those who live for the Kingdom
and those who live for themselves.
When the division comes,
it matters which side of the line we choose.
May we have the courage to stand with Christ,
who comes to set the world on fire!
