What does Romans 16:22 mean?

Paul is offering greetings to his readers in Rome from those who are with him in Corinth. In the previous verse, he sent greetings from Timothy, Lucius, and Jason. Paul apparently allowed his stenographer to add a greeting of his own. Nothing is known about Tertius outside of this verse. It was common in that era for letters to be dictated by the author, while a type of scribe—called an amanuensis—wrote them down. This was likely the role served by Tertius in this situation.

Paul regularly made use of an amanuensis. Some have speculated Paul had an issue with his eyes that made writing difficult. He ends his letter to the Galatians, for instance, by writing the words himself, pointing out what large letters he is using (Galatians 6:11).
