Philemon 1:23
Epaphroditus, my fellow prisoner, sends greetings to you, and so do Mark, Aristarchus, Demas, and Luke, my fellow workers — the list of salutations from co-workers and fellow prisoners witnesses to Paul's network and suffering for the gospel. Epaphroditus's status as fellow prisoner (syndesmios) affirms the serious nature of the imprisonment; the others represent the apostolic community surrounding Paul. Their greetings extend corporate endorsement of Paul's appeal to Philemon.
