Hostile discord

This line in Col 1.20 gives me pause:

...and through him to reconcile to himself all things, whether on earth or in heaven...

Just the last three words cause dissonance:“Or in heaven.”

Someone or something, in heaven, needed reconciliation? Wow.

Way back, long before the reconciliation at Golgotha, there was some heavy nastiness in the heavenlies, and one good-looking dude on a major ego trip had the trap door open on him. He fell hard and fast, and a whole bunch of his buddies were also swept out with the swish of a tail.

Is that what we are talking about here in Colossians? Did that event leave a stain, a hostile discord that necessitated reconciliation?

Perhaps.

But what do I know?
