With the resurgence of spirituality has come a renewed popular interest in angels. Thus, angels figure far more extensively in New Age thought than they have done in Christianity over the last two or three centuries. This essay explores the role angelology could potentially play in contemporary orthodox theology. It presents angels in terms of their function (ministering spirits) and being (inhabitants of heaven understood as a dimension of creation). Various roles for angelology are indicated: as a defense of the mystery of creation and its openness to God; as a possible element in dialogue with post-materialism; and as a part of contemporary Christian spirituality.
