Do I find unity in Christ with all believers? I recently read a book about tribalism in America. When I think of tribes, I think of Africa, but this book dealt with a much broader perspective. This book was about any group with a common interest. Folks stick together because they have a common ancestry, heritage, financial status, religious affiliation, social attraction, business interest, or hobby. I belong to several tribes: social community and church, my sports teams (New York Giants and the Chicago Cubs), my alma mater, and my political affiliation.
