This book offers an overview of angels in the Abrahamic religious traditions (i.e. Judaism, Christianity, and Islam.) [It does take a quick dip into angel-like beings from other religious traditions – e.g. Hindu and Parsi – but generally comes down on the side of it doing a disservice to everybody to equate such beings across mythological traditions – with the possible exception of the New Age angel which is predominantly an offshoot from Abrahamic mythology.] The book considers the evolution of theological thinking on angels: how they’ve been portrayed in art; what they are [made of;] what their purposes are (i.e. messengers, healers, guardians, warriors, etc.;) and, occasionally, how they play into popular culture.
I took away a great deal from this book. For example, I learned about the differences between the djinn of Islam mythology and demons of Judeo-Christian mythology, and the theological underpinnings of this difference (i.e. Muslims do not believe angels have free will, and thus angels can’t be fallen, and so the djinn are a separate entity altogether [rather than being fallen angels.]) I found the book to be readable, interesting, and balanced in its approach to the topic. If you’re looking to learn more about how angels (and related beings, e.g. fallen angels / demons) have been treated by thinkers of various ages, without getting deep into the minutiae, this is a fine book to consider.
