We #Quakers (or #Friends) don't have a creed,* that's part of what makes us who we are. So, there's not a lot of "This is what we believe!" out there. Doing some work for my monthly Meeting today, I happened upon a document I find really helpful. If you're #QuakerCurious this might be interesting for you: https://www.bethesdafriends.org/resources/Documents/Quaker-Speak-2019.pdf

*Edited to add: there are Quakers with written doctrines, and agreed-upon beliefs, too!
