Which of these sentences best summarizes the following passage (Paragraph 5)?
"Alien to the impertinences of the world, he only lifted his antiquarian eyes and murmured something in his dialect when Father Gonzaga went into the chicken coop and said good morning to him in Latin. The parish priest had his first suspicion of an imposter when he saw that he did not understand the language of God or know how to greet His ministers. Then he noticed that seen close up he was much too human; he had an unbearable smell of the outdoors, the back side of his wings was strewn with parasites and his main feathers had been mistreated by the terrestrial winds, and nothing about him measured up to the proud dignity of the angels. Then he came out of the chicken coop and in a brief sermon warned the curious aganist the risks of being ungenuous. He reminded them that the devil had the bad habit of making use of carnival tricks in order to confuse the unwary. He argued that if wings were not the essential element in determining the difference between a hawk and an airplane, they were even less so in recognition of angels."
