There is a sense
of urgency in today’s gospel. Jesus feels constrained or under stress until the
“fire” he has come to cast on the earth is kindled and the baptism of fire that
John the Baptist foreshadowed in 3:16 takes effect. Elsewhere in Luke’s
writing, fire is associated with judgement (3:9, 17; 9:17; 17:29), and with the
presence of the Holy Spirit (3:16), especially in the Lukan story of Pentecost
(Acts 2:3) where “tongues as of fire” appear and rest on all those assembled in
the upper room. Fire is a sign of the end times when the Spirit of prophecy
descends on all God’s people (Acts 2:18-19). Those who have experienced the
effect of the all too frequent bush fires in Australia or the wild fires of
California can appreciate the power of this image. Climate change is
undoubtedly increasing the risk of destructive fires. Drier conditions wither
plant life that then becomes fuel for the fires. Fire can take all before it.
It can also bring the most astonishing new life in its wake.

Linked with the
image of fire is that of water: Jesus has a “baptism with which to be
baptized”. Once more, a sense of urgency is expressed as the power of water is
evoked. Like fire, water has power to destroy and power to save. Fire and water
become metaphors for the hard won gospel path to peace. Jesus seems to be
contradicting so much of what he has stood for to this point. At his birth, he
is presented as the bringer of peace (Luke 1:79 and 2:14). He tells the
hospitable woman of 7:50 and the faith-filled woman of 8:48 to “go in peace”.
He instructs his disciples to bring peace to the families they visit (10:5-6).
He refuses to be a divider (12:13-14). And now he declares that he has come not
to bring peace but division. His hearers can expect members of families to be
divided one against another. How can this be?

The Lukan Jesus
is almost certainly describing the status quo rather than prescribing what
ought to prevail. In other words, by the time Luke is writing, it is clear that
some have accepted the gospel way of peace and justice and compassion and
others within the same families have not. Acceptance of the gospel and of Jesus
as the Christ or Messiah would have involved a monumental shift for Jews on the
one hand and for adherents of the diverse philosophies or faiths of the Roman
world on the other. Today’s families of mixed faith might be able to get inside
this experience and to understand the suffering involved when a family member
makes a life choice that other members of the family find hard to accept. This
is not an easy text to understand or even to accept. We need to struggle with
its ambiguity.
