"In this important book Anna Halafoff both maps out the history of what she terms the multifaith movement as well as looks at where it is today and where it may be headed. ... Halafoff's book is a welcome and significant contribution to such areas as Interreligious Studies, the sociology of religion, and religion and politics. ... I fully recommend this book to anyone looking at any of the issues discussed." (Paul Hedges, Journal for the Academic Study of Religion, Vol. 29 (1), 2016)
