This shortest of all Paul’s letters was addressed to Philemon (although two other persons are included in the salutation). Paul entreats Philemon, the master of Onesimus, a runaway slave, to receive him back as a brother in Christ (16, 17). This very personal letter reveals not only the concern of the Apostle for a converted slave but also a practical demonstration of brotherhood in Christ, "where there is neither bond (slave) nor free". (Gal 3:28)
