“Send them on their way in a manner worthy of God”
You will do well to send them on their way in a manner worthy of God. For they went out on behalf of the Name, accepting nothing from the Gentiles. Therefore we ought to support such men, so that we may be fellow workers for the truth. (3 John 1:6–8 BSB)
What it sounds like today
A polite send-off.
The cultural key
'Send on their journey' (propempo) was a loaded convention: provisioning, food, funds, introductions, sometimes escort for the next leg. The early mission ran on it: traveling teachers took nothing from outsiders ('the Gentiles'), so believers' hospitality was the entire supply line, and abusing it was common enough that the Didache soon wrote rules (a prophet who stays three days or asks for money is false). This letter exists because a local boss, Diotrephes, weaponized the system, refusing the travelers and expelling those who received them.
Recovered meaning
Hospitality as infrastructure: whoever provisions the messengers becomes a 'fellow worker for the truth' without leaving home. The whole shortest book of the New Testament is a dispute over a guest room, because the guest room was the mission's engine.
