σύμβολο

wiki says this about a creed

"A creed is a statement or confession of belief — usually religious belief — or faith. The word derives from the Latin: credo for I believe. It is sometimes called symbol (Greek: σύμβολο[ν]), signifying a "token" by which persons of like beliefs might recognize each other."
