Book excerpt: As Christians, we belong to not only a diverse global Christian family but also a diverse human family. Todd Johnson, a noted expert on global Christianity and world missions trends, and Cindy Wu show how divisions within these families work against our desire to bring about positive change in the world. They provide an overview of global Christian identity, exploring how we can be faithful to our own tradition while engaging Christians across denominations and be better informed as we work with people of other religions. The book utilizes the latest research data on global Christianity and world religions and includes tables, graphs, charts, and end-of-chapter discussion questions.
