- The Epistle to the Ephesians is the tenth book of the New Testament. According to its text, the letter was written by Paul the Apostle, an attribution that Christians traditionally accepted. However, starting in 1792, some scholars have claimed the letter is actually Deutero-Pauline, meaning that it is pseudepigrapha written in Paul’s name by a later author strongly influenced by Paul’s thought. According to one scholarly source, the letter was probably written “by a loyal disciple to sum up Paul’s teaching and to apply it to a new situation fifteen to twenty-five years after the Apostle’s death”.
