Vatican II ushered in a new outlook on living as Catholic Christians in a global world. This book is a student-friendly textbook on what it means to be human in light of our changing world and church. Each chapter will emphasize one particular aspect of human existence, exegeting the relevant biblical texts, classical and contemporary doctrines, and challenges to living these teachings in the twenty-first century. The book is divided into thirteen chapters, correlating with a typical length of a semester. Course instructors can shape their syllabi around this structure, perhaps dividing the week between lecture, discussion, and exercises, the latter of which will be outlined at the end of each chapter. This exploration of theological anthropology invites students from all levels, including undergraduate, seminary students, and engaged believers, into the conversation.
