The phrase "Good Samaritan" has a life of its own today even if the people who use it are not familiar with its source in the Gospel according to Luke, chapter 10. Here we read the full account of just a few unnamed characters:
- Robbers, whose power comes from stealth and from banding together
- the Traveler, who begins with the power and purpose to walk from one city to another and ends up completely powerless after the attack: wounded, lacking clothes and money
- the Priest & Levite, who come on the scene separately with the power of status and religiosity
- the Samaritan, with his donkey, who is considered racially inferior and a cultural foe.
 This is Andy Crouch's definition of power, given on page 17 of the book named above.
