Christ says: “Which of these three, do you think, proved neighbor to the man who fell among the robbers?” The Pharisee answers correctly, “The one who showed mercy to him” (Luke 10:36). This means that by doing your duty you easily discover who your neighbor is.… He towards whom I have a duty is my neighbor, and when I fulfill my duty, I prove that I am a neighbor. Christ does not speak about recognizing our neighbor but about being a neighbor yourself, about proving yourself to be a neighbor, something the Samaritan showed by his compassion. Choosing a lover, finding a friend, yes that is a long, hard job, but your neighbor is easy to recognize, easy to find – if you yourself will only recognize your duty and be a neighbor.
