What was the major problem in Ephesians?

Ephesians 6:12 speaks of the fight which is not against human foes, but against the "cosmic powers, authorities and potentates of this dark world, the superhuman forces of evil in the heavens." These archons were even thought of as having political organisations like rulers on earth.

However, this statement must not be thought of as coming from the Apostle Paul. Most scholars say that the Epistle to the Ephesians was written in Paul's name some time between 80 and 95 CE. One clear piece of evidence to support this is that many passages in Ephesians seem to be directly copied from the Epistle to the Colossians, itself a late pseudepigraphical work attributed to Paul.
