Tychicus was the kind of person every church needs: a messenger who could be trusted. Paul calls him “a beloved brother and faithful minister in the Lord” in Ephesians 6, and a fellow servant in Colossians 4. He carried Paul’s letters and spoke for him, sent so the readers would know how Paul was doing and so that he might comfort their hearts. Paul does not describe any miracle or sermon by him. What he offers is trust, news and encouragement from someone who had stayed close to a prisoner. Look at the closing verses of Ephesians 6 and Colossians 4 to meet him.

But that ye also may know my affairs, and how I do, Tychicus, a beloved brother and faithful minister in the Lord, shall make known to you all things:
Whom I have sent unto you for the same purpose, that ye might know our affairs, and that he might comfort your hearts.
All my state shall Tychicus declare unto you, who is a beloved brother, and a faithful minister and fellowservant in the Lord:
Whom I have sent unto you for the same purpose, that he might know your estate, and comfort your hearts;
Matthew George Easton, 1897
Chance, an Asiatic Christian, a “faithful minister in the Lord” (Eph. 6:21, 22), who, with Trophimus, accompanied Paul on a part of his journey from Macedonia to Jerusalem (Acts 20:4). He is alluded to also in Col. 4:7, Titus 3:12, and 2 Tim. 4:12 as having been with Paul at Rome, whence he sent him to Ephesus, probably for the purpose of building up and encouraging the church there.
William Smith, 1884
(fateful) and Troph’imus (nutritious), companions of St. Paul on some of his journeys, are mentioned as natives of Asia. (Acts 20:4; 21:29; 2 Timothy 4:20) (A.D. 54-64.) There is much probability in the conjecture that Tychicus and Trophimus were the two brethren who were associated with Titus. (2 Corinthians 8:16-24) in conducting the business of the collection for the poor Christians in Judea.
