Though possessing many
common cultural traits found also in Europe and the West, the much closer similarities between the cultures of Iran or Persia and India have led scholars to distinguish an Indo - Iranian branch of the larger whole as having early separated itself from the central or original Aryan migration, perhaps moving eastward from the, as yet, not certainly located origin of the Aryan group.
A few histories of local churches have examined the identifying
cultural traits of their subjects, exploring the symbolic patterns that give a particular congregation its unique character, instead of the far more
common topics of local church history, such as campaigns, catastrophes, and clergy.
