What are angels? They are intelligences of the human species. Many of them are offsprings of Adam and Eve. That is they are men, who have, like Enoch or Elijah, been translated; or, like Jesus Christ, been raised from the dead; consequently they possess a material body of flesh and bones, can eat, drink, walk, converse, reason, love, fight, wrestle, sing, or play on musical instruments. They can go or come on foreign missions, in heaven, earth, or hell; and they can travel space, and visit the different worlds, with all the ease and alacrity with which God and Christ do the same, being possessed of similar organizations, powers and attributes in a degree.
