The parables of chapter fifteen are justly regarded as the high point in Luke's Gospel. Frank Maloney
suggests that the journey narrative is composed in just three parts: the lead-up to this chapter, chapter fifteen itself, and the lead-down from it. For Frank, these three parables embody the kernel of Jesus’ teaching on the way to Jerusalem. Together with the Parable of the Great Dinner, they tell us that
Jesus passionately believes God wishes ALL to be saved and struggles desperately to save all, but also, that struggle as God might, God may very well not succeed. The obstacles are not at all according to the will of God, for
example the elder boy’s reasons for refusing to enter the feast are entirely perverse, while the father’s reaction is extraordinarily patient. ‘Then the father said to him, ‘Son, you are always with me, and all that is mine is yours. But we had to celebrate and rejoice, because this brother of yours was dead and has come to life; he was lost and has been found.’ The warning of  an  absolute obstacle remains however: presumption of entitlement coupled with contempt for others, be they ever so lowly, may very well end by defeating even the all-embracing love of God.

Luke 15:1-3, 11b-32

1 Now all the tax collectors and sinners were coming near to listen to him. 2 And the Pharisees and the scribes were grumbling and saying, “This fellow welcomes sinners and eats with them.” 3 So he told them this parable:

“There was a man who had two sons. 12 The younger of them said to his father, ‘Father, give me the share of the property that will belong to me.’ So he divided his property between them. 13 A few days later the younger son gathered all he had and traveled to a distant country, and there he squandered his property in dissolute living. 14 When he had spent everything, a severe famine took place throughout that country, and he began to be in need. 15 So he went and hired himself out to one of the citizens of that country, who sent him to his fields to feed the pigs. 16 He would gladly have filled himself with the pods that the pigs were eating; and no one gave him anything. 17 But when he came to himself he said, ‘How many of my father’s hired hands have bread enough and to spare, but here I am dying of hunger! 18 I will get up and go to my father, and I will say to him, “Father, I have sinned against heaven and before you; 19 I am no longer worthy to be called your son; treat me like one of your hired hands.” ’ 20 So he set off and went to his father. But while he was still far off, his father saw him and was filled with compassion; he ran and put his arms around him and kissed him. 21 Then the son said to him, ‘Father, I have sinned against heaven and before you; I am no longer worthy to be called your son.’22 But the father said to his slaves, ‘Quickly, bring out a robe—the best one—and put it on him; put a ring on his finger and sandals on his feet. 23 And get the fatted calf and kill it, and let us eat and celebrate; 24 for this son of mine was dead and is alive again; he was lost and is found!’ And they began to celebrate. 25 “Now his elder son was in the field; and when he came and approached the house, he heard music and dancing. 26 He called one of the slaves and asked what was going on. 27 He replied, ‘Your brother has come, and your father has killed the fatted calf, because he has got him back safe and sound.’ 28 Then he became angry and refused to go in. His father came out and began to plead with him. 29 But he answered his father, ‘Listen! For all these years I have been working like a slave for you, and I have never disobeyed your command; yet you have never given me even a young goat so that I might celebrate with my friends. 30 But when this son of yours came back, who has devoured your property with prostitutes, you killed the fatted calf for him!’ 31 Then the father said to him, ‘Son, you are always with me, and all that is mine is yours. 32 But we had to celebrate and rejoice, because this brother of yours was dead and has come to life; he was lost and has been found.’ ”
