"The Epistle of Paul to the Colossians, usually referred to simply as Colossians, is the 12th book of the New Testament," according to Wikipedia. "It was written, according to the text, by Paul the Apostle and Timothy to the Church in Colossae, a small Phrygian city near Laodicea and approximately 100 miles (160 km) from Ephesus in Asia Minor.
"Scholars have increasingly questioned Paul's authorship and attributed the letter to an early follower instead. The authenticity of the letter, however, has been defended with equal strength.
"During the first generation after Jesus, Paul's epistles to various churches helped establish early Christian theology. According to Bruce Metzger, it was written in the 50s while Paul was in prison. Colossians is similar to Ephesians, also written at this time.
"Some critical scholars have ascribed the epistle to an early follower writing as Paul. The epistle's description of Christ as pre-eminent over creation marks it, for some scholars, as representing an advanced christology not present during Paul's lifetime. Defenders of Pauline authorship cite the work's similarities to Philemon, which is broadly accepted as authentic."
