Chapter 2: Gifts needed by an abbot or abbess (paragraph 4)

Otherwise all must keep their proper place in the community order, because whether slave or free we are all one in Christ and we owe an equal service in the army of one Lord, who shows no special favour to one rather than another. (From para. 4 of Ch. 2 of Saint Benedict's Rule, trans. by Patrick Barry, OSB, 1997.)

Benedict's words are "culture-upending".  Jesus came to call us friends, and to teach us how to be in right relationship with each other.  The army metaphor falls short for me here, because Benedict is describing a culture transformed into one of peace and justice.
