(sorry I'm late!) Paul has a familiar theme as he closes this letter: bringing the church together. Not only reminding masters in power that they must be fair, but also extending special greetings to specific people and praising the work of several. Can you imagine being present in a small house church, hearing your name read from the letter of Paul? It must have been a great encouragement to these believers, and probably helped smaller house churches get to know one another better.
