The Prison Epistles had been the ones which had been written by Paul when the period of imprisonment for Paul in Rome had started (Doole). Ephesians, Philippians, Colossians, and Philemon are the epistles which are categorized under the Prison Epistles (Doole). The audience/readers addressed for Ephesians, Philippians and Colossians had been individuals living in the cities of Ephesus, Philippi and Colossae respectively (Doole). However, the epistle to Philemon had not been addressed to any group of individuals but to a single individual named Philemon who had not understood the true meaning of forgiveness.
