We are living in a moment in history when we as a species have to ask, What do we have in common? The boundaries are melting between cultures and religions. This makes it important to have a serious discussion of our tradition of angels in the West, not out of jingoism but out of knowing our own tradition well enough so that when we encounter angels and spirits from other traditions, we are not put off or threatened by them. Instead, we can look for the common links, the common truths among the traditions.
