Reading the World from the Borders
Oscar García-Johnson, PhD.

 

A bilingual decolonial theology archive cultivating public theological imagination from the borders.

Migration is not merely where theology is applied nowadays. It is one of the places where theology is born.

Dear colleagues,

One of the disciplines of doctoral education is learning to recognize location, not just data. It’s a movement from what is being published to where knowledge is happening.

Scholarship is never simply a collection of books and articles. It is an ecology of conversations, assumptions, silences, and emerging possibilities. Our vocation as researchers is to cultivate the intellectual and spiritual attentiveness necessary to discern those movements.

During the past month I have been struck by an important convergence across theology, migration studies, ecclesiology, public theology, and World Christianity. Increasingly, scholars are no longer asking how theology should respond to migration or how Christian communities ought to address colonial histories. A deeper methodological question is emerging:

What forms of theological knowledge become possible when migrants, Indigenous peoples, border communities, and historically marginalized Christians are understood as producers—not merely recipients—of theological knowledge?

That question is reshaping several disciplines simultaneously. More importantly, it is inviting us to reconsider what counts as theology, where theology is generated, and whose voices become authoritative in its construction.

This month’s brief traces five trajectories that I believe deserve sustained attention.

         

Trajectory I

Migration as a Theological Location

Migration is increasingly being understood as more than a social phenomenon requiring pastoral care.

Across recent scholarship—from migrant women constructing theology through lived experience, to Indigenous communities interpreting Christian faith through ancestral practices, to African and Asian diasporic churches negotiating new forms of belonging—migration itself becomes a theological location.

This represents a significant methodological shift.

The migrant is no longer merely the object of theological reflection.

Migration becomes locus theologicus—one of the places from which theology emerges.

For those of us interested in border ecclesiality, this confirms an intuition that has shaped much of my own work: border communities are not simply sites of ministry. They are sites of theological imagination.

Toward Epistemic Justice

The questions we ask at the beginning of research change accordingly.

“How does theology respond to migration?”

we are now asking

“How does migration generate theology?”

Trajectory II

Decoloniality Is Becoming “Parasitic” to Research Method

One of the most encouraging developments concerns methodology.

For many years decolonial scholarship has excelled at exposing colonial assumptions embedded within institutions, theological education, and systems of knowledge.

Current scholarship increasingly asks another question.

What does research actually look like after colonial critique?

Across recent studies, attention shifts toward:

  • participatory knowledge
  • Indigenous epistemologies
  • collaborative inquiry
  • locational intersectionality
  • non-extractive research
  • alternative forms of evidence

This movement is particularly significant for critical thinking, practical theology, qualitative research, and participatory action research.

Our task is no longer only to critique extractive scholarship.

Our task is to imagine—and practice—research that itself embodies justice.

Trajectory III

Border Ecclesiality Beyond Institutional Thinking

Several recent books suggest that ecclesiology is quietly changing.

Church increasingly appears less as institution and more as:

• hospitality

• sanctuary

• shared memory

• translation

• improvisation

• public witness

• communal discernment

Migration is forcing ecclesiology to reconsider assumptions inherited from Christendom.

Concepts such as hybridity and interculturality remain valuable, yet they often begin with stable cultures entering dialogue.

Border communities invite another possibility.

Let’s admit that Christian communities have always been constituted through overlapping worlds of belonging, asymmetrical histories, and ongoing translation.

This intuition continues to shape my own exploration of border ecclesiality.

How does the church become recognizable amid displacement, contested belonging, and pluriversal worlds of knowing?

             

Trajectory IV

Pneumatology Beyond Abstraction

Another noteworthy development concerns renewed attention to the Holy Spirit.

Recent scholarship approaches pneumatology through:

  • migration
  • Indigenous wisdom
  • embodied vulnerability
  • diasporic imagination
  • intercultural ecclesial life
  • communal discernment

The Spirit appears less as an abstract doctrinal topic and more as the One who animates communities navigating uncertainty, displacement, and hope. My core claim in Spirit Outside the Gate (2019).

At the same time, scholarship on Christian nationalism reminds us that spiritual language can also be mobilized in service of domination. An argument I make in Embracing Fear (2025).

This sharpens an important theological challenge.

A decolonial pneumatology must distinguish between spiritual practices that cultivate liberation and those that sanctify conquest, exclusion, or authoritarian belonging.

That distinction, I suspect, will become increasingly important over the coming decade.

Trajectory V

Public Theology from Below

Perhaps the most significant shift concerns public theology.

Rather than beginning with theories of the public sphere, several scholars reconstruct public theology through sanctuary movements, labor organizing, migrant communities, Indigenous struggles, and everyday practices of resistance.

Theology in the public sphere increasingly appears not as theology translated into public language—of public domain.

It emerges, for better or worse, from communities struggling to survive, organize, remember, and hope but also dominate, possess, and exclude.

The public is not merely where theology is communicated.

It becomes one of the places where theology is produced: dominion theology or Liberation theology.

An invitation to linger

Questions the Spirit Leaves Us

Before beginning your next article, chapter, or dissertation proposal, linger with these questions.

Where is theological knowledge emerging that your discipline still refuses to recognize?

What assumptions about church, mission, or public life remain invisible because they have become familiar?

If migrants, Indigenous communities, and people living at the borders are genuine producers of theological knowledge, how should that reshape your research design?

How does your own location—social, institutional, linguistic, and ecclesial—shape what you are able to see and what you are likely to overlook?

What kind of church becomes imaginable if borders are understood not only as sites of suffering but also as places of revelation?

A shared practice

A Pedagogical Invitation

Read this month’s literature slowly.

Read comparatively.

Read beyond disciplinary boundaries.

Most importantly, read with enough humility to allow your research questions to change.

Doctoral education is not merely preparation for writing a dissertation.

It is apprenticeship in the responsible production of theological knowledge.

Our calling is to cultivate scholarship marked by conceptual rigor, methodological integrity, ecclesial accountability, and intellectual generosity—not as ends in themselves, but in service of communities seeking justice, reconciliation, faithful public witness, and abundant life.

My hope is that this monthly letter becomes more than an annotated bibliography.

I hope it becomes a shared practice of attentiveness.

Together, may we learn to recognize where the Spirit is opening new intellectual horizons for the church and the academy—and may we have the courage to follow.

With gratitude for your scholarship and companionship,
