This article explores the application of neoinstitutional theory to re
ligious organizations, focusing on how institutionalized myths and rit
uals of ecclesiastical authority influence members' behavior and attit
udes toward organizational policy. Research done on hierarchical and d
ecentralized religious polities (which are structures of church govern
ment) reveal differential processes of informing parishioners about ch
urch policy. Hierarchical (or ''tightly structured'') religious instit
utions foster knowledge of organizational policy because of the myths
and rituals of recognized ecclesiastical authority, while decentralize
d (or ''loosely structured'') religious institutions, whose myths and
rituals focus on local autonomy, rely upon members' external motivatio
n for awareness of organizational policy. In part, this article argues
for the theoretical usefulness of the application of neoinstitutional
theory to various organizational fields, such as religious organizati
ons.
