One of my readings, from the book of Tobias (one of the books of the Apocrypha), describes the Angel Raphael taking on the form of a man, a man recognizable by others as a member of a particular family. A footnote to the scripture stated the angel personated the man.
Thinking about angels personating men reminded me of the movie, City of Angels. The premise is endearing, but flawed. How romantic to think a heavenly being would be so passionately in love, he would give up his angel status and become human. On more than one occasion Hollywood has implied this world is far better than the next, and all life would choose to be human.
