So how much control do they have then? How far does their rule extend?
Ruler, leader, adviser, counselor, brother?
When the Israelite's wanted to be like the other nations to have a king (ruler) over them (rather than remain with no king and have God continue as their only king) they were told of the problems that would come 1 Sam 8. Any ruler other than Christ is prone to problems (1 Sam 8:3).
Were not Joshua and Caleb both leaders of God's people and yet they were not always followed.
Was not Nathan an adviser to David (2 Sam 7:3) and what about Ahithophel (2 Sam 16:23). Yet even Ahithophel was not always in harmony with God's will.
When David sinned in relation to Uriah (Bathsheba) did not Nathan counsel David (2 Sam 12) but he did not rule him.
When it came to the Christian congregation, did not leadership create issues as some said they followed different men (1 Cor 1:12)
All men in Christ are brothers.
There is a major difference between a "Ruler" and a leader, adviser, counselor, brother
Only one of those seeks power.
For a man or even a group of men to claim the right to " rule" as opposed to, lead, advise, counsel, is dangerous. Is not Christ our "Ruler" ? Do not all others need to come under Christ in every matter?
Acts 20: 28-30 makes it clear that the responsibility is to "shepherd" the flock for those who would "rule" are better described in verses 29-30.
A "ruler" sets laws that must be obeyed. A shepherd however guides and leads.
A "ruler" sets the standard by what he thinks is right, a shepherd leads the sheep to consider the word of God and thus it is still God that rules as the standard is not that of any man.
In the gates of a city what was the role of the older men? They all had the law and the standards of God, thus those older men did not "rule" but rather simply had to be sure that the people in dispute were adhering to what was already written.
And how are they appointed and are there checks and balances or are they rulers for life? Suddenly I'm starting to get an inkling of how the Catholics ended up with a pope.
When it comes to the criteria for those that would shepherd the flock, the very first thing would need to be that they are no part of the world (John 17:16-17). If we still mix in the teachings and beliefs of Christendom that have pagan roots, then can we truly claim to be no part of the world?
Should not the attitude be like Paul (Eph 3:8) and see ourselves as the least among our brothers.
If the flock is loved and Lead to follow Christ then it does not need to be "ruled".
