"7 Tychicus will tell you all about my activities. He is a beloved brother and faithful minister and fellow servant in the Lord. 8 I have sent him to you for this very purpose, that you may know how we are and that he may encourage your hearts, 9 and with him Onesimus, our faithful and beloved brother, who is one of you. They will tell you of everything that has taken place here.
10 Aristarchus my fellow prisoner greets you, and Mark the cousin of Barnabas (concerning whom you have received instructions—if he comes to you, welcome him), 11 and Jesus who is called Justus. These are the only men of the circumcision among my fellow workers for the kingdom of God, and they have been a comfort to me. 12 Epaphras, who is one of you, a servant of Christ Jesus, greets you, always struggling on your behalf in his prayers, that you may stand mature and fully assured in all the will of God. 13 For I bear him witness that he has worked hard for you and for those in Laodicea and in Hierapolis. 14 Luke the beloved physician greets you, as does Demas. 15 Give my greetings to the brothers at Laodicea, and to Nympha and the church in her house. 16 And when this letter has been read among you, have it also read in the church of the Laodiceans; and see that you also read the letter from Laodicea. 17 And say to Archippus, “See that you fulfil the ministry that you have received in the Lord.”
18 I, Paul, write this greeting with my own hand. Remember my chains. Grace be with you."
Colossians 4:7-18
It was, you will remember, in response to Epaphras' news (1:7-8) of dangerous teaching troubling the newly established churches in the Lycus Valley, that Paul, full of concern, drafted this letter. The letter is now sent by the hands of Tychicus and Onesimus, Paul's fellow-workers, to the church in Colossae (vv 7-9). Tychicus, it seems, was Paul's special envoy, at this time, to the churches of Asia Minor which had been established during Paul's earlier ministry in Ephesus (Acts 19:10). Paul himself was under arrest in Rome and unable to travel, so, full of loving concern for the work of the gospel and for the welfare of the believers, he sent Tychicus to Asia, to minister in his place and Tychicus (Acts 20:4; 2 Timothy 4:12; Titus 3:12) carried letters from Paul to the various churches. Tychicus was certainly the bearer of Paul's Ephesian letter (6:21-22), this letter to the Colossians (4:7-8) and more than likely, Paul's lost letter to the Laodiceans (4:16).
