I'm writing a research paper on the Quakers, a religious group that arose in the 1600's. Anyways, I was writing a sentence and I can't figure out the correct comma usage:
The “Inward Light” was believed by Quakers to be the inner apprehension, or fear, of God.
Should I have a second comma before "of God"? Or should I write it like this:
The “Inward Light” was believed by Quakers to be the inner apprehension, or fear of God.
I am not trying to define apprehension as the "fear of God", but rather trying to show the reader that may not understand the word apprehension in the context a less formal synonym, "fear". Thanks for the help.
