In the preface to Grassroots Asian Theology: Thinking the faith from the ground up, Simon Chan heightens one’s reading expectations. Although the title implies a study on Asian theology, Chan holds out the spectra of developing an “authentic” and “vibrant” theology “that will yield a better theology for the Asian church and perhaps the global church as well.” Chan notes the perspective of an ancient church father, St. Prosper of Aquitaine, that belief is expressed through worship and prayer. The church’s participation in prayer and worship is the articulation of their belief or theology. Aquitaine’s Lex Orandi, Lex Credendi, is the church engaging “belief in a way that simply thinking about God or studying the faith does not naturally do. In other words, in an act of worship, the faithful are in dialogue with God and are engaged in an active and personal relationship with Jesus Christ.”
It is significant that Chan provides more than a perception or an interpretation on Asian theology. The author’s approach to “thinking the faith from the ground up” expresses well the concept of a “grassroots” theology made up of “lived experiences.” This is true in the context of Asian culture but in other world cultures as well. Chan states “Contextual theologies emerge as the church lives out its given script in new situations. In other words, theology is first a lived experience of the church before it is a set of ideas formulated by church theologians.” The practice of prayer and worship should determine the statement of belief.
Chan’s presentation on and application of methodologies opens an abundance of concepts that relate to contextualizing the gospel in local culture. How do we develop a local theology? What has theology and local culture to do with each other? We live in an era of globalization where culture, multicultural, crosscultural, multiethnic and contextualizing the gospel are concepts that communities of faith (the local church) encounter in everyday ministry. Theology must engage people in everyday life. To paraphrase Chan, “a local theology is the Christian Faith in a local context.”
These concepts are reminiscent of the faith and theology concepts in Who needs Theology?: An Invitation to the Study of God by Stanley Grenz and Roger Olsen. Grenz and Olsen recognize that “anyone who reflects on life’s ultimate questions … is a theologian.” In addition, “theology is seeking to understand with the intellect what the heart … already believes and is committed to.” In a similar manner, Chan notes that “Theology comes as much from the Laity … as it does from the theologian.” In Who Needs Theology, the authors present theology on a spectrum from folk theology to academic theology; authenticity is determined by the extent of deliberative reflection coupled with the willingness to pursue the goal to deeply understand one’s beliefs.
Deliberative theology leads to constructive contextual application. Theological beliefs are relevant to contemporary culture. “Good theology is never content to remain on the theoretical level; it always affects life.”
Chan presents a similar concept in relating “lived theology” and “elitist theology.” He notes that the ecclesial experience (meaning the lived-out beliefs of the church) ought to be central to primary theology. “The task of the professional theologian is not to tell the church what is good for it but to listen carefully what the Spirit of truth who indwells the church is saying through the people of God.” Chan characterizes the Spirit’s work in the lives of everyday Christians as “perhaps the most successful contextualization of the gospel the world has ever seen.”This is the application of a “Folk Christianity” that defines theological belief and tradition as the Spirit practice of the gospel in culturally diverse communities. “Christianity as a lived reality among ordinary folks has the unique characteristic of both preserving tradition and also changing it as it adapts to new challenges.” Grenz and Olsen express this same concept when they state, “Theology does not invent beliefs; it finds beliefs already among Christians and critically examines them.”
In chapters 2 through 6 Chan engages in presenting a grassroots Asian theology. Although not inclusive of all Christian belief, he presents the context for the following: God and the Trinity, humanity and sin, Christ and salvation, Holy Spirit and spirituality, and the church. He engages belief/faith, lived theology, culture and context using the processes of “ressourcement and aggiornamento.” By ressourcement, Chan is referring to Christian tradition as the guiding resource in developing an authentic Christian theology. He cites his sources through the book as “catholic and orthodox.” Perhaps this source gives creditability as an elitist (academic) bases for his Asian theology. He defines aggiornamento as the “adaptation and updating in light of the new situations in which the church finds itself” in a postmodern deconstructionist era. Perhaps this gives creditability to the contextualized theology that is lived by the church in every cultural circumstance. It is through maintaining a tension between these two processes for developing a theology that Chan provides a model for local church theology. He concludes, “This way of construing theology is not only closer to the Asian spirit at the grassroots level but also consistent with the larger Christian tradition. It is this correlation that validates its claim to universality. An authentic Asian theology is not just for the church in Asia but for the worldwide church.”
