There’s currently a pretty interesting Facebook discussion on “measure of light.” Colloquially, I’ve heard this phrase used as a way to reassure us that we don’t all have to have the same abilities. We shouldn’t be jealous of others, who might have other talents in the body of Christ. Our goal is to live up to the light of what we’ve each been given as individuals.
Reading Robert Barclay, where much of this language comes from, I’m not sure he would agree:
By this Seed, Grace, and Word of God, and Light, wherewith we say every man is enlightened, and hath a measure of it, which strives with them in order to save them, and which may, by the stubbornness and wickedness of man’s will, be quenched, bruised, wounded, pressed down, slain and crucified; we understand not the proper essence and nature of God, precisely taken, which is not divisible into parts and measures, as being a most pure, simple being, void of all composition or division, and therefore can neither be resisted, hurt, wounded, crucified, or slain by all the efforts and strength of men.
An Apology for the True Christian Divinity. Robert Barclay, 1678
He’s pretty clear that the light is indivisible so I don’t see how it could be more or less within any of us or change over time (though certainly our awareness of it can be strengthened as we progress spiritually). And for him, and all early Quakers, the Light was very definitely God working within us. Nowadays it’s more common for Liberal Friends to think of it as a kind of spiritual conscience.
I myself wouldn’t want to get into deciding who has what ability. Maybe talents is a better way of thinking about it. Like, in my humanness I may get jealous that someone gives really good ministry in worship. But maybe that’s not my gift. There are some people I’ve met who are always extremely thoughtful of others. And others who are really good at centering a group down in worship. I have friends who are always great about getting to know everyone in their lives. We can aspire to be better in all these things but there are people who seem more naturally suited to this. So we should try to live up to our measure in our spiritual lives but not feel bad about ourselves if others are able to do certain things effortlessly.
