After the parenthetical NEGATIVE EXAMPLE of "the
ENEMIES of the CROSS of CHRIST ... who MIND EARTHLY things" (Philippians 3:18-19) - Paul returns to the POSITIVE EXAMPLE (Philippians 3:17) of those whose FOCUS is on their HEAVENLY CITIZENSHIP (Philippians 3:20):
The Greek word "politeuma" (Philippians 3:20)
is related to the Greek word "politeia" rendered "FREEDOM" (Acts 22:28) - the CONTEXT in this case, clearly pertaining to Paul's Roman CITIZENSHIP
(Acts 22:25-27)
Another related Greek word "polites" is used
in reference to Paul's EARTHLY native CITIZENSHIP of Tarsus - "a city in Cilicia. a CITIZEN of no mean (common)
city" (Acts 21:39)
A very ILLUMINATING PARALLEL is drawn with the Lord's
"BEING" (Greek, "HUPARCHO") God in essence (Philippians 2:6) and the believer's citizenship which "IS" (Greek, "HUPARCHO")
in heaven (Philippians 3:20) - the Greek word "HUPARCHO" literally meaning "FROM
THE BEGINNING"
This is consistent with what God says about the BEGINNING
of the "the CHURCH, which is His BODY" (Ephesians 1:22-23) - "CHOSEN ... IN HIM" (Ephesians 1:4), i.e. IN CHRIST - "BEFORE the FOUNDATION (OVERTHROW) of the WORLD"
(Ephesians 1:4)
