Early Christian-Muslim Debate on the Unity of God examines the writings of three of the earliest known Christian theologians to write comprehensive theological works in Arabic. Theodore Abū Qurra, Abū Rā’iṭa and ‘Ammār al-Baṣrī provide valuable insight into early Christian-Muslim debate shortly after the rise of the Islamic empire. Through close examination of their writings on the doctrine of the Trinity, Sara Husseini demonstrates the creativity of these theologians, who make use of language, style and argumentation characteristic of Islamic theological thought (kalām), in order to help articulate their long-established religious truths. Husseini offers close analysis of the authors individually and comparatively, exploring their engagement with Islamic theology and their role in this fascinating period.

Christian-Muslim Relations, Volume 15, Thematic Essays (600-1600) is a further volume in a general history of relations between the two faiths from the 7th century to the early 20th century. The chapters within it illustrate the range, complexity, and dynamics of interaction between the two faiths during the first thousand years of encounter. All chapters primarily draw upon entries found in volumes 1-7 of Christian-Muslim Relations. They explore tropes of perception, image and judgement that each religious community held in respect to the other through these centuries, and discuss issues and topics that occupied Christians and Muslims in their interaction. The first millennium sets the scene for the modern era and our understandings of contemporary relations and issues. Contributors are Mark Beaumont, Clinton Bennett, David Bertaina, Ulisse Ceceni, David Bryan Cook, Martha Frederiks, Ayşe İçöz, Sandra Keating, James Harry Morris, Nicholas Morton, Gordon Nickel, Juan Pedro Monferrer Sala, Tom Papademetriou, Gabriel Said Reynolds, Christian Sahner, Mark N.

In Muslim-Christian Polemics across the Mediterranean Diego R. Sarrió Cucarella provides an exposition and analysis of Shihāb al-Dīn al-Qarāfī’s (d. 684/1285) Splendid Replies to Insolent Questions (al-Ajwiba al-fākhira ‘an al-as’ila al-fājira). Written in response to an apology for Christianity by the Melkite Bishop of Sidon, Paul of Antioch, the Splendid Replies is among the most extensive and most important medieval Muslim refutations of Christianity, and the primary significance of this study is to provide detailed access to its argumentation and intellectual context for the first time in a western language. Moreover, the Introduction and Conclusion creatively situate the work within the challenges of modern-day Christian-Muslim dialogue.

This Reader brings together nearly 80 extracts from major works by Christians and Muslims that reflect their reciprocal knowledge and attitudes. It spans the period from the early 7th century, when Islam originated, to 1500. The general introduction provides a historical and geographical summary of Christian-Muslim encounters in the period and a short account of the religious, intellectual and social circumstances in which encounters took place and works were written. Topics from the Christian perspective include: condemnations of the Qur'an as a fake and Muhammad as a fraud, depictions of Islam as a sign of the final judgement, and proofs that it was a Christian heresy. On the Muslim side they include: demonstrations of the Bible as corrupt, proofs that Christian doctrines were illogical, comments on the inferior status of Christians, and accounts of Christian and Muslim scholars in collaboration together. Each of the six parts contains the following pedagogical features: -A short introduction -An introduction to each passage and author -Notes explaining terms that readers might not have previously encountered

A key area of disagreement between Christians and Muslims is the nature of God: Is God a Trinity or absolutely one? Applying insights from early Arabic Christian theologians and philosophers to current conversations, Sherene Nicholas Khouri offers both historical and constructive responses to Islamic objections to the doctrine of the Trinity.

How do intellectual traditions interact? This is the fundamental question driving this book, which explores a case study set in the early Islamicate world: the Treatise on Divine Unity According to the Doctrine of the Christians by the Christian-Arabic theologian and philosopher Yaḥyā ibn ʿAdī (d. 974). The book attempts to contextualise the treatise and its intellectual environment by exploring the interplay between philosophy, Christian theology and Islam. This volume includes a revised Arabic text of Samir’s 2015 edition, collated with the manuscript Tehran, Madrasa-yi Marwī 19, recently discovered by prof. Robert Wisnovsky.

Since the first interactions between Christians and Muslims, a central point of contention has been the nature of God in relation to the doctrine of the trinity and divine oneness. Yet the belief that God is one is vociferously upheld by Christians, Jews and Muslims alike. In this detailed historical study and subsequent analysis, Dr Michael F. Kuhn explores the teaching of two Arab Christian theologians from the Abbasid Era (750–1250), ‘Abd Allāh Ibn al-Ṭayyib and Iliyyā of Nisibis, and how they defended the Christian view of God as three-in-one in the Muslim milieu and in reference to the Islamic concept of tawḥīd, God’s absolute unity. The intellectual contribution of these two Christian thinkers can be seen in fact that the concepts they articulated continue to feature in Muslim–Christian dialogue to this day. Dr Kuhn shows the great lengths that Middle Eastern Christians went to explain their view of God’s oneness in the Trinity and the divinity of Christ to their fellow Christians and to commend it to their Muslim counterparts. There is much to learn from the historical debates investigated in this book to help Christians today to uphold the truth of the Christian scriptures, both in the Muslim context and beyond. Readers will appreciate the review of Nestorian Christology in light of recent studies and the important theological background to contemporary Muslim–Christian engagement that is provided. This book also makes a significant addition to the Christian understanding of the Trinity by linking the eternal attributes of God, a common theme in Islamic thought, to the three persons of the God-head deepening our understanding of the inter-relations of Father, Son and Holy Spirit. Anyone engaging intellectually or academically with Muslims with hopes to dialogue thoughtfully in the area of theology, spirituality and ethics will find this book acutely helpful.
