What do all of these things have in common? They are models or structures for churches.
But when we are not careful they are distractions from the real issue; Leadership.
I am reminded of the overplayed FUN song, "Some Nights." There is a line in the song, "This is it boys, this is war, what are we waiting for, lets break the rules already."
Good leaders know that structures/models are just suggestions and good leaders exercise liberty and freedom where needed. Bad leaders treat the structures/models as Rigid rules we should not sway from.
The Bible never proposes a "model" or "structure" for church. The genius in God's manual for life was to allow the church to form around its' host cultures' needs. You see several Churches in the Bible but there is never a mandate for structure. Baptize new converts and observe the Lord's supper.... that's pretty much it. What the Bible is specific on, is the character of the men you put in charge. You can find RIGID detail in I&II Timothy and Titus as to who the leaders need to be.
Good leadership can make a bad system work, but bad leadership can make a great system fail.
