"Church history does not supply a normative authority for Christian worship, but it does supply a didactic authority that we would be foolish to ignore...Both the accomplishments and the mistakes of the past bring didactic and diagnostic help to us as we attempt to faithfully worship according to the Scripture in our own time and cultural situation...Not that our worship can ever be a mere photocopy of the past; but an appreciation of the devotional treasures of the ages bequeathed to us in the legacy of the historic worship of the church helps us resist the rampant chronological snobbery of our own age."J. Ligon Duncan III, Give Praise to God pp. 60, 61
