I call Gabriel "the golden one", because in my view, everything about her is like golden fire -- her hair, her eyes, her wings . . . and, of course, her heart. She is warm and gentle, though certainly she can flare up when the situation calls for it! But this isn't often at all. In fact, according to my recollections, the only angel who could ever be described as any gentler than Gabriel would have been Anael.
She's incredibly beautiful, of course . . . but I always got the sense that she was somewhat lonely, in a sense -- at least a little bit. That's what I remember of being "up there", anyway.
Magnificat anima mea Dominum!
