Animals and Humans
610. There are spirits who have said that human beings are separate from the rest of creation. Are they mistaken?
“No, but the question has not been fully developed. Similarly, there are things that we can only know at a predetermined time. Humans are distinct beings because they have abilities that separate them from all others and they have another destiny. God chose the human species for the incarnation of beings who are capable of knowing their Creator.”
