The Foolish Father

  Luke 15.31-32   You are always here with me, and everything I have is
yours. But we had to celebrate and be happy because your brother was
dead and now he is alive.

The parable of the Prodigal Son has a long and chequered history. For
most of the time since it was first interpreted by the author of Luke's
Gospel, it has been seen as a call by Jesus for repentance from a
sinful lifestyle (the younger son). He contrasts with wicked people who
refuse the Good News (the older son).

Many now think that a better interpretation is to see a forgiving God
in the father. We will always be welcomed home (the Church) if we turn
our backs on loose living (the younger son). There are those who
angrily think the whole Christian thing epitomises blind error (the
older son). The truth is much more dramatic.

Many in the 21st century are unable to hear this parable as Jesus first
told it because their culture is too different from that of the first
century. There are those in the older world who stand a better chance
because their cultures haven't changed that much in the last two
millennia.

The first hearers of this parable would have been shocked at the
father's behaviour. Their culture, based on tradition and the Hebrew
scriptures, warned specifically against any man giving away his
inheritance while still alive. The elder son would inherit two-thirds
of his estate. The younger son or sons would split the remaining third.
  Women got nothing. These rules were in place not to benefit the sons
but to protect the family. No sound father in Jesus' time would have
accepted the insulting tone of the older brother. He would have forced
his son to capitulate and come to the party. Instead, in the parable it
is the father who capitulates. He demeans himself intolerably when he
pleads with his son instead of disciplining him.

 The younger son was a scoundrel, the elder an upstart, and the father
a fool. All three put at risk the extended family. Life in those times
was precarious enough without such self-centred nonsense. Worse still,
this was a relatively wealthy family. How could the father jeopardise
its security by being so soft?

Those listening to Jesus would have been forcibly struck by the
parable. They would have asked themselves what Jesus was getting at.
What would have happened when the father died, for instance?

Every preacher at this point is tempted to take a next step by asking,
"What is the point of the parable?" That Jesus intended his listeners
to reflect on themselves and their situations in the light of the
parable is, I think, without doubt. But it's highly questionable that
he intended to make a specific point.

What does the wastrel son say to you? Which of the three characters do
you see yourself as? Should you be more pliable in your life? Or are
you called on to get tough with others?
