Citadel of Faith is a collection of letters from Shoghi Effendi to the Baha’is of North America written between 1947 and 1957. It gives insight into the crises and victories faced by the American believers, through the lens of the guidance provided by a loving Guardian throughout the last decade of his earthly life.

The value of this collection lies not only in the glimpse it gives into an important period of history but in the perspective it provides on the present, and in the ready application of the principles identified to the issues of the current time.
