Whatever you did for one of the least of these brothers and sisters of mine, you did for me. Matthew 25:40b
“Our life and our death are with our neighbor. If we do good to our neighbor, we do good to God; if we cause our neighbor to stumble, we sin against Christ.”
Anthony, Desert Father (c. 270) as recounted in Where God Happens: Discovering Christ in One Another by Rowan Williams, the Archbishop of Canterbury (Boston: Shambhala, 2005) 130.
