For over forty years, John Garvey was the "ballast" of Commonweal magazine. His award-winning essays and consistently notable columns revealed not only his acuity and alacrity, but his uncommon spiritual insight. These in turn provided momentum and substance for whatever followed in an issue of the magazine because Garvey never hesitated to wrestle with some of the most challenging and intractable topics of the day, and did so with a rich pastoral sensitivity, and a refreshing and rare intelligence. Only Wonder Comprehends gleans from John Garvey's many contributions to Commonweal that reflect his spiritual depth and deep appreciation of history, politics, theology, and culture. Steeped in the Christian tradition, Garvey loved to write and, in return, his readers relished what he wrote. It is hoped that this collection of his writings from Commonweal will inspire readers to cultivate a similar sense of attentiveness and commitment, for as the author himself observed, "Religious traditions are meant to transform us, not to affirm us as we are."

The Xi'an Stele, erected in Tang China's capital in 781, describes in both Syriac and Chinese the existence of Christian communities in northern China. While scholars have so far considered the Stele exclusively in relation to the Chinese cultural and historical context, Todd Godwin here demonstrates that it can only be fully understood by reconstructing the complex connections that existed between the Church of the East, Sasanian aristocratic culture and the Tang Empire (617-907) between the fall of the Sasanian Persian Empire (225-651) and the birth of the Abbasid Caliphate (762-1258). Through close textual re-analysis of the Stele and by drawing on ancient sources in Syriac, Greek, Arabic and Chinese, Godwin demonstrates that Tang China (617-907) was a cosmopolitan milieu where multiple religious traditions, namely Buddhism, Zoroastrianism, Manichaeism and Christianity, formed zones of elite culture. Syriac Christianity in fact remained powerful in Persia throughout the period, and Christianity - not Zoroastrianism - was officially regarded by the Tang government as 'The Persian Religion'.Persian Christians at the Chinese Court uncovers the role played by Syriac Christianity in the economic and cultural integration of late Sasanian Iran and China, and is important reading for all scholars of the Church of the East, China and the Middle East in the medieval period.
