In ancient times, documents that were falsely attributed to an author, called pseudepigrapha, were a common phenomenon. Both the Letters to the Colossians and Ephesians are most likely pseudonymous works attributed to the Apostle Paul. The writer of Colossians assures his readers that they already possess all the benefits of salvation and do not need to observe rules concerning feast days, Sabbaths, and worship of the angels. Ephesians seems somewhat based on Colossians, although it reads more like an ethical or moral treatise. Both letters differ from Pauline Christology in their realized eschatology and high Christology.
