We are still traveling. It is worth noting that Paul, who had no base (we have one) worked with a group. The sole preacher, the sole prophet, should be held in suspicion. Paul wanted his letters to circulate. His fellow workers were Jewish and Gentiles, united in faith.
But he knew most believers were not traveling full time. They had a base, they had a church (often in a richer person’s house). Which is why he commends to them certain people and instructs them to circulate teachings.
7 As to all my affairs, Tychicus, our beloved brother and faithful servant and fellow bond-servant in the Lord, will bring you information. 8 For I have sent him to you for this very purpose, that you may know about our circumstances and that he may encourage your hearts; 9 and with him Onesimus, our faithful and beloved brother, who is one of your number. They will inform you about the whole situation here.
10 Aristarchus, my fellow prisoner, sends you his greetings; and also Barnabas’s cousin Mark (about whom you received nstructions; if he comes to you, welcome him); 11 and also Jesus who is called Justus; these are the only fellow workers for the kingdom of God who are from the circumcision, and they have proved to be an encouragement to me. 12 Epaphras, who is one of your number, a bondslave of Jesus Christ, sends you his greetings, always laboring earnestly for you in his prayers, that you may stand perfect and fully assured in all the will of God. 13 For I testify for him that he has a deep concern for you and for those who are in Laodicea and Hierapolis. 14 Luke, the beloved physician, sends you his greetings, and also Demas. 15 Greet the brethren who are in Laodicea and also Nympha and the church that is in her house. 16 When this letter is read among you, have it also read in the church of the Laodiceans; and you, for your part read my letter that is coming from Laodicea. 17 Say to Archippus, “Take heed to the ministry which you have received in the Lord, that you may fulfill it.”
