THE apostle Paul encouraged the congregation in Philippi to “behave in a manner worthy of the good news.” (Read Philippians 1:27.) The Greek expression that Paul used for the word “behave” may also be rendered “carry on as citizens.” That phrase had special significance for the congregation in Philippi. Why? Because it seems that Philippi was one of a select group of cities where the inhabitants had been granted a form of Roman citizenship. Roman citizens in Philippi and throughout the Roman Empire were proud of their status and enjoyed special protection under Roman law.
The church in Philippi was just another local church like any other of the local churches that Paul ministered to.
They may have been more firmly established judging from how things were in good order as to leadership and serving. Other than that I see no reason for you making anything special about the church in Philippi.
Members of the congregation in Philippi had greater reason for being proud. Paul reminded them that as anointed Christians their citizenship existed “in the heavens.” (Phil. 3:20) They were citizens, not of a mere human empire, but of God’s Kingdom. As such, they enjoyed unparalleled protection and benefits.—Eph. 2:19-22.
There was nothing going on in the church there that was not going on in any of the other churches.
"For our commonwealth exists in the heavens, from which also we eagerly await a Savior, the Lord Jesus Christ" (3:20)
was true of the church in Corinth or Thessalonika as well.
It is true every Christian today in any locality on earth in spite of any problems one might point out.
The transfiguration of the body is a hope placed before the Christians in Philippi as well as the Christians in Corinth - Compare Phil. 3:20,21
and First Corinthians 15:51-53
What Paul is speaking to Philippi is in no way not the common hope extended to every other congregation in the New Testament. Why are you trying to make some place special of the church in Philippi ?
Paul’s admonition to “carry on as citizens” applies principally to those who will rule with Christ in heaven. (Phil. 3:20) But by extension, it can be applied to those who will be the earthly subjects of God’s Kingdom.
The letter to Ephesus speaks of fellow citizens with the saints and members of the household of God in a most universal and common way.
"In whom you also are being built together into a dwelling place of God in spirit." (Eph. 2:22)
The words "you also"
mean that what all the other churches were experiencing in the building up of God's habitation the recipients of the Ephesian letter ALSO were co-partakers of the same experience.
And "you also"
is at the end of a list of matters Paul says apply to the recipients of the Ephesian epistle, including "you are fellow citizens with the saints and members of the household of God" (v.19)
The terms "fellow citizens"
are so closely related that I think you're making an artificial issue.
Why? Because all dedicated Christians serve the same King, Jehovah, and must live up to the same standards. (Eph. 4:4-6) Today, people work hard to qualify to become citizens of a prosperous country. How much more should we value the opportunity to be Kingdom citizens!
The King is Jesus Christ and in His return He has a name "King of kings"
"And I saw heaven opened, and behold, a white horse, and He who sits on it called Faithful and True, and in righteousness He judges and makes war. ...And He has on His garment and on His thigh a name written, KING OF KINGS AND LORD OF LORDS." (Revelation 19:11,16, Recovery Version)
Towards the Body the church Christ is the Head.
Towards the kingdom of the heavens Christ is the King.
By the way Matthew's term "kingdom of the heavens"
does not mean the kingdom which is only in heaven. It means the kingdom, the SOURCE of which is in heaven.
When Jesus told Pilate that His kingdom was not of this world (John 18:36)
He meant that the source of His kingdom was not of this world but is sourced in heaven.
Jesus returns and wages war against Antichrist as the " Lord of lords and King of kings "
"These will make war with the Lamb, and the Lamb will overcome them, for He is Lord of lords and King of kings ..." (Rev. 17:14a)
Since Jesus Christ is Jehovah God incarnate as the Son He is the divine King.
" ... keep the commandment spotless ... until the appearing of our Lord Jesus Christ, which in its own times the blessed and only Sovereign will show, the King of those who reign as kings and Lord of those who rule as lords,
Who alone has immortality, dwelling in unapproachable light, whom no man has seen nor can see, to whom be honor and eternal might. Amen." (1 Tim 6:14-16)
" ... the Lamb will overcome them, for He
[the Lamb] is Lord of lords and King of kings ..." (Rev. 17:14)
