The Epistle of Philemon

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 concerns of the Apostle for a converted slave but is also a practical demonstration of brotherhood in Christ, where there is neither bond (slave) or free" (Gal 3:28)
