In this letter to the holy-people (Christians), Paul teaches regarding
the resurrected Christ's authority, which God has given to him - both in
relation to the spirit-realm and to the physical-realm.
The Phrygian city of Colosse was only a few miles from Laodicea and
Hierapolis. It is only in recent times that the sites of these cities
were discovered.
This letter may have been written during Paul's imprisonment in Caesarea
(Acts 23:33-27:2) or it may have been written about 62/63 AD when Paul
was a prisoner in Rome and stayed in his hired-house (Acts 28:16-31).
