Colossians names Mark, Luke, and Demas among Paul’s associates; 2 Timothy names the same coworkers while reporting their later circumstances. The overlap shows continuity in Paul’s coworker network across the two letters.

Acts narrates the dispute over John Mark between Barnabas and Paul; Colossians later identifies Mark as Barnabas’s cousin and includes him among Paul’s coworkers, illuminating a restored ministry relationship.

Acts 19 identifies Aristarchus as one of Paul’s companions during the Ephesian riot, while Colossians later names Aristarchus among Paul’s close coworker circle. The uncommon personal name gives the relationship biographical weight rather than mere thematic similarity.

Acts 20 includes Aristarchus among Paul’s traveling companions, and Colossians later names the same man among Paul’s coworker circle. The relationship is a biographical continuity link across the mission record and the letter.

Acts 27 places Aristarchus on Paul’s voyage toward Rome, while Colossians calls Aristarchus a fellow prisoner. The overlap strongly supports coworker continuity, but it does not by itself prove that Colossians was written during the Roman voyage or imprisonment.

Epaphras, Mark, Aristarchus, Demas, and Luke appear in both Philemon’s closing greetings and Colossians 4. Five overlapping coworkers make the social connection between the two letters unusually dense.
