Is there a King to rule the earth in justice and peace? If so... How does He respond to those who do not recognize Him as Sovereign?

Kings of Babylon, kings of Persia, were brought under His hand. Also the nations who pursued an ethic of leadership under "the wise ones", the priviledged, a gerontocracy; elders being recognized as to guide/direct a community or nation, such as the free citizens of Greece. Then to the Roman Republic, with its Senate [council of elders] as an elder-led nation, later receiving Galus Octavianus as their first emperor in 27 B.C., after having been a republic for ~500 years.

The lens of empire became embedded -- even wed to the physical church at Rome. In reflection, events recorded from Acts chapter 15 are today understood within the Roman church as to showcase Simon Peter being primary; leader of the ekklesia --- even though the Acts 15 account more accurately reflects a more sure leadership as described from Matthew 23:1-14.

How do we keep our true King,
   while ruling and reigning with Him?

Let none think of self more highly than he ought. [Romans 12]
Here's the story...

 end of community failure


What happened to those who continued together?
What was to follow for those distracted away
from the Kingdom of God?

Ecumenical: meaning of one house. The historic ecumenical councils pursued the idea of all faithful in Christ brought within a single household on earth. Early, it became apparent that ecumenicism fell short of YHWH's purpose for His own: His birthing of a holy εθος [ethos, nation]; a peculiar people; His Kingdom as being greater than a single household. Arius was rejected by the first ecumenical council at Nicaea, but afterward he gradually received more of a welcome -- even among some of the council who had condemned and sent him away.
We are, great & small, called to be representing Christ together and in the holy Spirit, on earth as it is in heaven.

Then it seemed good to the apostles and elders and all of the ekklesia…

--from Acts 15:22
