We cannot speak of the form or shape of purely spiritual beings. God has no form or shape. Shape supposes dimensional arrangement, and dimensions suppose quantity of matter. Angels can exert spiritual force, and even will the action of natural physical forces with God’s permission. If at times they have appeared to men in bodily forms, they have but assumed appearances not proper to them, and most probably formed from the material atmospheric elements in order to manifest their presence in a way in keeping with man’s lower level.
