The heart of this word is the in-between role: a person who acts for someone else, carrying a message, running an errand, or executing an assignment given by a superior. The defining relationship is not to the people the agent helps but to the one who sent him. That is why the same word can name:

• a waiter at a feast
• a king's official
• a herald of the gods
• a minister of the gospel
• a recognized officer of the church

In each case the person is acting under a mandate from above and standing between that authority and others.

This is a single idea worn in different settings, not several unrelated words. The aide who waits at a banquet, the agent God sends to do his bidding, the spokesman who carries the gospel for Christ, and the church officer entrusted with a recognized task are all the same kind of figure: a trusted representative carrying out a commission. The teaching that the great person must become everyone's servant takes that ordinary role and makes it the surprising shape of true greatness, and the word can even be turned on a questionable cause, asking whose agent someone really is.

For a long time this word was read as if its core were lowly waiting at table, so that Christians supposedly chose a degraded term to express humble love. The better-grounded reading is that the word names commissioned, mediating activity, neither slavery nor menial drudgery. The New Testament still attaches a striking theology to it, because the agent God sends acts through self-giving and suffering, but that humility is the shape the commission takes, not the bare meaning of the word.
