It seems clear that in at least some parables there is an analogical correspondence between some character in the parable and Jesus. For instance, in the parable of the tenants in Luke 20, most would interpret the character of the son in reference to Jesus.
In the parable of the Good Samaritan in Luke 10:25-37, two characters stand out as potential analogies to Jesus. The man attacked by robbers has clear parallels to Jesus as the one who suffers and who is rejected by the priests. But also the Samaritan seems to have analogy to Jesus in the gospel as the one who brings salvation and who bears the costs of the other.
Obviously the parable has meaning on the ethical level in relation to the “who is my neighbor” question. But does the parable also have an analogical meaning? And if so, does one of these characters fit better into that level of meaning?
