According to Pope Benedict XVI, The parables bear meaning in every age because we find in them the person of Jesus. In comparison to other allegorical interpretation of texts that were prevalent in the time of Jesus, Jesus’ parables stand out as a piece of real life. The parable is a proclamation of the Kingdom of God, which is realized in the person of Jesus. This is why the parable is a call for faith in Jesus and this call is made anew to all peoples at every age.
But there is a bit of confusion when Jesus says he talks to the people in parables else they be converted and be healed. To understand this, one has to put Jesus in the line of the prophets, for through what He suffered, he draws our attention to the true sign of faith in Him: the cross. Jesus knows the demands of the Kingdom and the possibility of refusal. It is only by gazing on His cross that even the hardened heart can finally “turn and be forgiven.”
The point of the parables is to lead us to the deepest meaning the Kingdom. This deepest meaning of the Kingdom is the cross. The parable of the good Samaritan is an example of how we can be more like Jesus, by going out of our way, on the everyday road from Jerusalem to Jericho where we see humanity beaten, stripped, and lying half-dead. The parable is an invitation for us believe and follow Jesus not just figuratively but in the reality of human history. Unless a grain of wheat falls to the ground and dies, it will not bear fruit.
