“The word “interspirituality” was nonexistent until it was coined in 1999 by a Roman Catholic lay monk and pioneer interfaith leader, Brother Wayne Teasdale, in a book aptly entitled The Mystic Heart: Discovering a Universal Spirituality in the World’s Religions. By 2004, when Brother Teasdale and colleagues introduced the perspective at the Parliament of the World’s Religions in Barcelona, Spain, the term was still hardly known. Yet today an internet search for “interspirituality” or “interspiritual” calls up over 100,000 hits.
