To Philemon our beloved fellow worker and Apphia our sister and Archippus our fellow soldier, and the church in your house: - Philemon 1-2
When Paul was an old man and a prisoner for Christ Jesus, he sends Onesimus back to his master Philemon and asks in the epistle Philemon to welcome him as he would Paul, make him a brother not a bondservant, and to charge his wrongs and debts to Paul to repay. He sends the epistle Philemon to Philemon, Apphia, Archippus, and the church that meets in Philemon's house.
(Philemon)
