My friend Razi went to a Quaker summer camp in Virginia called Shiloh Quaker Camp for several years as a kid. She learned a number of folk songs with Quaker themes as a camper there. The following is a recording of Razi singing a song about George Fox, one of the founders of Quakerism, which she learned at camp and often sings, along with the lyrics:

There’s a light that was shining in the heart of man
It’s a light that was shining when the world began
There’s a light that is shining in the Turk and the Jew
There’s a light that is shining friend in me and in you (hey)

Walk in the light wherever you may be
Why don’t you walk in the light wherever you may be?
“In my old leather britches and my shaggy, shaggy locks,
I am walking in the glory of the light,” said Fox.

“There’s a bell and a steeple and a book and a key
That will bind him forever but you can’t,” said he,
“For the book it will perish and the steeple will fall
But the light will be shining at the end of it all” (hey)

Walk in the light wherever you may be
Why don’t you walk in the light wherever you may be?
“In my old leather britches and my shaggy shaggy locks,
I am walking in the glory of the light,” said Fox.

This song specifically celebrates the Quaker belief of the “inner light” or “light of God,” but its morals can be embraced by non-Quakers as well. Quakerism is a particularly open religion in terms of its acceptance of other religions, so songs that come out of the tradition can often be sung with the same conviction by people who have to particular affiliation with the religion. Razi is Jewish and agnostic, but she agrees with many of the values taught at Quaker camp, so songs like this one have stuck with her.
