Tychicus of Asia
It is evident that the Apostle Paul placed a great deal of confidence in Tychicus, whom he called “a beloved brother, faithful minister, and fellow servant” (Col. 4:7; cf. Eph. 6:21).
Although we are not certain exactly when Tychicus was joined to Paul’s evangelism team, the New Testament provides enough facts about him to warrant a sound conjecture on the subject. The earliest certain information we have on Tychicus (information, that is, apart from Titus 3:12, a text difficult to date) places him in Macedonia and then Troas in early spring of A.D. 58. This data comes from Acts 20:4, which also tells us that Tychicus was a native of Asia Minor.
It seems reasonable, then, to think of his coming under the influence of Paul duri . . .
