1 Corinthians 11:18-19
18. For, in the first place, when you come together as a church, I hear that divisions exist among you; and in part I believe it.
19. For there must (dei - "it is necessary") also be factions among you, so that those who are approved may become evident among you. NASV
The last phrase of these two verses gives us the reasons why divisions and disagreements are necessary in the church. " . . . so that those who are approved may become evident among you."
It seems quite clear that the kind of leadership that is approved of God, the kind of leaders that the church should follow, are those who are tolerant of other views, who graciously and lovingly accept people of different persuasions and opinions, and who place charity as the highest value within the church (I Corinthians 13).
In His Grace,
