"Isn’t it noteworthy in the parable of the Good Samaritan that Jesus does not give a straightforward answer to the question "Who is my neighbor?" (Luke 10:29). Surely he could have provided a catalog of those whom the scribe could love as himself as the law required. He does not. Instead, he tells a story. It is as if Jesus wanted among other things to point out that life is a bit more complex; it has too many ambivalences and ambiguities to allow always for a straightforward and simplistic answer. ."
