Why do sinful human beings think of angels as cute little bambini, lovable old bumbling frumps, androgynous pretty-boys and feathered friends? The Bible depicts them as terrifying messengers, who fill their startled beholders with panic and sickness unto dread. In Ezekiel, they are described as freaky frightening extraterrestrial beings with multiple faces (beast and human), as well as having myriad eyes covering their fiery bodies. Angels must first allay the fears of the humans they encounter before they are able to get their message across.
Who & what exactly are the messengers of Heaven ?
