"My prayer is not for them alone. I pray also for those who will believe in me through their message, that all of them may be one, Father, just as you are in me and I am in you. ... I have given them the glory that you gave me, that they may be one as we are one-- I in them and you in me--so that they may be brought to complete unity. Then the world will know that you sent me and have loved them even as you have loved me." (Jn 17:20-23) In That They May Be One, pastor and professor Gary Agee offers personal and pastoral reflections of his own journey towards embracing unity with the other. His humorous anecdotes and thoughtful insights invite others to consider how his experiences are also theirs. In addition to the guidance offered by Agee's own stories of unity with people of other religious beliefs and racial ethnicities, each chapter poses questions for personal reflection and discussion which will prompt practice of the unity within reach. Agee prophetically centers Christian communities in the Upper Room, the location of Pentecost, where the transformed disciples were united with one mission before being sent out to evangelize the world. This book will surely initiate, or further, instrumental dialogue at both a personal and institutional level over the postures and behaviors that are needed to encourage unity in the evermore diverse communities that Christians belong to.
