This is the introductory volume of a multivolume, verse-by-verse, interfaith rereading of the New Testament letter to the Ephesians. It looks to the Tiantai Buddhist master Zhiyi and his "threefold truth" to enhance our appreciation of nascent trinitarian themes in Ephesians. And it draws upon a broad array of scientific, theological, and philosophical thinkers in aid of rejecting the epistle's ancient, geocentric cosmology and its accommodations to the misogynistic, patriarchal, and slaveholding norms of its first-century surroundings. As a whole, the work constitutes a twenty-first century apologetic for doctrinal humility and for theologizing within a global theological commons.

This is volume 2 of a wide-ranging interfaith reading of the Letter to the Ephesians—a New Testament text whose words have inspired and enhanced Christian spiritual life and liturgy over the centuries. Unfortunately, at the same time, Ephesians has provided apparent scriptural support to those who would defend slavery, patriarchy, misogyny, and the physical power of Christ over the cosmos. How on earth are today’s Christians to receive and understand such a text as this? Earthing the Cosmic Christ of Ephesians: The Universe, Trinity, and Zhiyi’s Threefold Truth draws upon a broad array of scientific, theological, and philosophical thinkers who enable us both to marvel at today’s ever-expanding knowledge of our vast cosmos and to appreciate the importance of the Ephesian letter in the canon of our Christian scriptures, even while we acknowledge the archaic geocentric cosmology that underlies its claims about the cosmic Christ and reject its accommodation to the patriarchal, misogynistic, and slaveholding norms of its first-century culture. Throughout this reading of Ephesians, we look to Chinese Buddhist master Zhiyi and his “threefold truth” to enhance our understanding of trinity and the nascent trinitarian themes within this letter. As a whole, this work constitutes a new appreciation for Ephesians as well as a twenty-first century apologetic for doctrinal humility and for theologizing within a global theological commons.

As both a scholar of Buddhism and a Christian priest, John P. Keenan engages with the New Testament letter to the Ephesians, written by a member of the Pauline school likely near the end of the first century—a time when both the cultural world and the cosmos were much narrower than for us today. In pondering this scripture’s significance for residents of the twenty-first century, Keenan looks to the work of scholars and thinkers both ancient and modern, Eastern and Western, scientists and philosophers. Particular attention is given to Chinese Buddhist master Zhiyi’s explanation of a threefold truth, which resonates with an early trinitarian theme in Ephesians and suggests the riches to be discovered upon the global theological commons.

In a Tiantai theology, conventional truth is conventionally arisen, which means that such truth is never set once and for all, but is to be cherished and rethought in new circumstances, whether interreligious or scientific—but always in critical consonance with its ancient embodiments. Contexts shift frameworks, but life in Christ is translatable across cultures. Christian faith and theology discourage the assumption that the point of it can be clearly pinned down. God’s appearance to Elijah out of the whirlwind is an eternal reminder of the paltriness of all human perspectives. Symbolic worlds of faith and wisdom are not themselves finished products. Because it has a past and a future, the cosmos itself is unfinished. Christian creeds ought not be defended as last-word ideological positions and bastions against relativity, but instead recognized in their cultural contexts and affirmed as grammars of communal and personal assent.

Before the Gospels were written, long before the creeds of the Church were hammered out, Christ followers in Philippi sang a hymn of the Christ who, "although he was in the form of God . . . emptied himself, taking the form of a slave, being born as are all humans." But this emptied Christ never fit neatly into later theologies of the church, shaped by Greek thought, concerned with being and essence. In Philippians, Paul struggles, stumbling over his own awkward words to express his hope, his eschatological faith, that he might "gain Christ and be found in him . . . and participate in his sufferings by being conformed to his death, if in some way I may reach to what goes beyond the resurrection from the dead." Might we better comprehend Paul's inchoate, even mystical, faith in Jesus Christ with aid from a less empirical world of thought than our western heritage offers? Might the thinking of Mahā[set macron over a]yā[set macron over a]na Buddhism guide us toward an awareness of a truth in the Christian faith that is more profound than anything reducible to historical "facts," or even to human language?
