'God wills to exercise the 'abundance' of his glory-to create as many reflections as possible of his own being. But if the point of the world is the abounding plurality of such reflections, each must exist within limits, since God alone is infinite.'

'Compatible variety means the harmony of genuinely distinct subjects.'

Rowan Williams on Richard Hooker

Haven't read Achebe but did come across this:

“Wherever something stands, something else will stand beside it.” Achebe often used this proverb in discussing his work, and he explained its significance once in an interview: “It means there is no one way to anything….If there is one God, fine, there will be others as well…. If there is one point of view, fine. There will be a second point of view.”
