Rom 13:1 Let every soul be subject unto the higher powers. For there is no power but of God: the powers that be are ordained of God.
1Pe 2:13 ¶ Submit yourselves to every ordinance of man for the Lord's sake: whether it be to the king, as supreme;
1Pe 2:14 Or unto governors, as unto them that are sent by him for the punishment of evildoers, and for the praise of them that do well.
1Pe 2:15 For so is the will of God, that with well doing ye may put to silence the ignorance of foolish men:
1Pe 2:16 As free, and not using [your] liberty for a cloke of maliciousness, but as the servants of God.
1Pe 2:17 Honour all [men]. Love the brotherhood. Fear God. Honour the king.
No one is under any obligation to join a man made organization or denomination, but once you do, behave yourself and live according to the instructions given to you by the Apostle of the Lord here, and for the sake of Christ, the laws of the organization. These eccelesiastical magistrates ARE ordained of God for the purpose that they are placed there because there IS no power that is not ordained of God.
Once bound to those laws though it is not sin, it could become iniquitous when one operates outside the laws of Divine Love to engage in political intrigue and stealth for the sake of wordly power outside the kingdom laws of LOVE. To behave CONTRARY to those laws renders that malcontent a rebel against established, God ordained powers.
God knows that there is a lot of wicked, political intrigue that goes on in those denominations and organizations. To use those methods to gain power or advance an agenda is wicked. However, no one within that fellowship is compelled to participate in that wickeness. It is the way of WORLDLINESS which character we are told to love NOT. It will pass away and the LUST thereof along with it.
Meanwhile, rebellion is as wicked as it is the core of the spirit of a rebel to be a political animal in the darkest sense of intrigue and stealth. Flee from such for many of these appear before the unsuspecting eye as an angel (messenger) of light.
