The Book of Philemon is a short letter in the New Testament of the Christian Bible, traditionally attributed to the Apostle Paul. It addresses a Christian named Philemon, who is a slave owner, and concerns a runaway slave named Onesimus. Paul writes to encourage Philemon to forgive Onesimus and accept him back, not just as a slave but as a brother in Christ. This letter highlights themes of forgiveness, reconciliation, and the transformative power of faith. It is often studied for its insights into early Christian attitudes toward slavery and the importance of treating all individuals with dignity and respect.
