I was proud of my miniature roll-top desk. Such an arrangement is great for organizing secular work, but not a good model for Christianity. Again, Christ was killed because he refused to fit into anyone's pigeon hole. It was deemed necessary to kill the prophets because they too refused to be pigeon holed. The problem is still with us.
Denominations are simply religious pigeon holes into which the members are crammed for safekeeping.
It is difficult to see out of a pigeon hole, and that does keep adherents in line. Denominations don't want members peeking into other pigeon holes, or worse yet, trying to determine what God is doing without hierarchical supervision. Pigeon hole Christians also serve a pigeon hole god. One that can be held prisoner in a denominational box. Not very flattering for one supposedly free in Christ.
