I was talking with a young person who was teaching at one of the Indian Reservations in South Dakota. She told me of a time she was administering a test when one of the students began sharing the answers with his classmates. She told him to stop cheating. He did not understand her concern. He explained, that anything he had, or anything he knew, was not for his own benefit but was meant to benefit the tribe. Since he knew the answer and they didn’t, he was obliged to share what he knew for the good of the tribe. It made this young teacher stop and think — do we really need to build society on competition and possessiveness? The early Christians who “held all things in common” didn’t think so.
