American Christianity has bred a suspicion of creeds. Yet, a creed connects us with Christians across time, space and denomination. Before he died, Jaroslav Pelikan gave an interview about his multivolume collection of Christian Creeds (outlined in his book Credo).
Pelikan also published a 5 volume history of Christian Doctrine. His defining of the role and development of tradition and its relation to Christian faith helps Protestants accept tradition while maintaining the supremecy of the Scriptures. As Pelikan says in his interview: "The only substitute for tradition is bad tradition" (i.e. the tradition you make up and try to pass on)
