text: Today, a number of scholars believe that Philippians is a composite of multiple letter fragments. According to the theologian G. Walter Hansen, "The traditional view that Philippians was composed as one letter in the form presented in the NT [New Testament] can no longer claim widespread support." Nevertheless, most scholars currently support the literary unity of Philippians.
  Regardless of the literary unity of the letter, scholars agree that the material that was compiled into the Epistle to the Philippians was originally composed in Greek, sometime during the 50s or early 60s AD.
  Place of writing
  It is uncertain where Paul was when he wrote the letter(s) that make up Philippians. Internal evidence in the letter itself points clearly to it being composed while Paul was in custody, but it is unclear which period of imprisonment the letter refers to. If the testimony of the Acts of the Apostles is to be trusted, candidates would include the Roman imprisonment at the end of Acts, and the earlier Caesarean imprisonment. Any identification of the place of writing of Philippians is complicated by the fact that some scholars view Acts as being an unreliable source of information about the early Church.
  Jim Reiher has suggested that the letters could stem from the second period of Roman imprisonment attested by early church fathers. The main reasons suggested for a later date include:
  The letter's highly developed Ecclesiology
  An impending sense of death permeating the letter
