What is a human being? What makes humans special, different from other creatures? Or is a human just another animal? Drawing on Scripture, Aquinas, and science, this book seeks to articulate both why and how humans should be understood as special. Despite amazing similarities to other creatures, humans are physiologically, psychologically, and spiritually unique beings. No other creatures--not even angels--have the unique combination of capacities nor the divine calling that humans have. Vanden Berg argues that only humans are material-spiritual, intellective, worshipping beings created specifically for a personal relationship with their Creator and with the stated vocation of caring for God's world and representing God in it.
