"Since the medieval period, Christians and Muslims have been dialoguing about the nature of God. Carefully working through the thought of medieval Arab Christians, Sherene Khouri shows how they articulated and defended the Trinity in their contexts. This study offers wisdom for Christians today discussing God's relationality with Muslim friends."

"Most Western Christians are unaware that Christianity predates Islam on the Arabian peninsula, that Christians interacted intellectually with Arabs in the centuries after the rise of Islam, that much of this interaction consisted of discussions about the Trinity, and that Christians in the region even adopted Arabic as their spoken and written language. For modern Christians interacting with Muslims today, the history of the early interchanges between the two faiths is crucially important. Furthermore, modern Christians who seek to articulate the doctrine of the Trinity in a world that regards it as nonsense would do well to draw on the riches of early Arab Christian writing on this most central doctrine of our faith, in response to their neighbors who also thought this doctrine was illogical. For both sets of modern readers, this book provides a great service as it describes the Christian understanding of God, who is intrinsically and eternally relational, in contrast to the Muslim conception of Allah as merely contingently relational. "

"Sherene's insights on the Trinity were gained through a combination of God's providential hand in her life and her personal thirst for the truth of God. We are all privileged to have the result of God's grace and Sherene's diligence as expressed in this fine work. I share with Sherene in prayer and in hope that this work will accelerate the necessary dialogue between Christians, Muslims, and all who seek to know God better."

"Triune Relationality shares with readers the riches of Eastern Christian theological tradition. As Christians today reflect on dialogue with Islam, they will benefit immensely from Khouri's thoughtful presentation of three Christian theological masters who lived under early Muslim rule and defended not only the coherence but also the beauty of Christian doctrine on the Trinity and the incarnation."
