I took a Bible timeline Seminar, and without going back to my notes I’m gonna say we were told that the prodigal son represented the Jews and the other son the Gentiles, but then again that could be vica versa.
There are different takes, here’s my understanding:
Christ tells three parables here, and all three are related, so they must all be read to understand what Jesus is teaching.
The context for the identity of the prodigal and the older son is in the first two verses:
V1 has tax collectors and sinners coming to listen to Jesus.
V2 has Pharisees and scribes listening, and grumbling, “this man receives sinners and eats with them.” Notice the attitude of these scribes and Pharisees; it is the same as that of the older son at the end of the story.
Without going into an expostion of the whole parable, the prodigal son represents the Jewish nation as a whole (tax collectors, and sinners), and ultimately those of that nation who put their faith in Christ.
The “older son,” represents the scribes and Pharisees, who were not happy with those Jews who followed Christ; in fact, they persecuted them, and put them out of the synogogues.
The father represents God.
The prodigal recognized that he was a sinner, and that he had rebelled against his father, and squandered all of the inheritance his father had given him; he also was brought to the realization that he had no righteousness in himself, and so threw himself on the mercy of the his father, and was willing to be the least of his father’s servants.
The older son, who had done the will of his father, and had been faithful and obedient to his father’s house and all of his father’s laws, was angry when he saw the love of the father lavished on the prodigal, who had been so disobedient to his father, and so sinful.
The point of the teaching of all three parables is found in vv7, 10, 32; that is, the joy in heaven over the repentance of one sinner; the great mercy of God is seen as well in the attitude of the father toward the prodigal, as well as toward the older the son; God has not forsaken Israel; there final salvation is yet future. There are many other tidbits in the text, but I’ll stop here.
For a similar parable with a different point, read Lk 18:9-14.
