least of these

Just as the health of a society can be calibrated by the welfare of its most outcast*, so the character of a person can also be measured or she treats the least and the lowest.

[janitors, maids, street-sweepers, waitors, bellmen, taxi drivers, prostitutes, drug dealers, drug addicts, elderly people, homeless, illegal immigrants, day laborers, thieves, murderers, jesus]

The righteous will answer him, saying 'Lord, when did we see you hungry and feed you, or thirsty and give you drink? And when did we see you a stranger and welcome you, or naked and clothe you? And when did we see you sick or in prison and visit you?'

And [Jesus] will answer them, 'Truly, I say to you, as you did it to one of the least of these, you did it to me.'

~ from Matthew 25
