Les grandes traditions chrétiennes, en leurs propres termes

Catholic, Eastern Orthodox, Oriental Orthodox, Reformed, Lutheran, Anglican, Baptist, Wesleyan-Methodist, Pentecostal-Charismatic, and Evangelical — plus two major schools that cut across Latin Christianity, Thomism and Augustinianism. Each tradition has a dedicated Christian AI voice grounded in its own magisterial or confessional sources.

No. Each tradition is presented on its own terms using its own primary sources — conciliar documents, confessions, catechisms, and leading theologians within that tradition. When traditions disagree, the AI names the disagreement rather than papering over it.

Comparative overviews usually summarise traditions from the outside. Here each tradition's expert speaks from inside that tradition's grammar — liturgy, doctrine, spiritual practices, and characteristic emphases — the way a well-formed adherent would explain it.

Yes. Ask any tradition's expert how it differs from another — "How does Orthodox pneumatology differ from the Reformed?" — and the AI will answer from the first tradition's perspective with explicit citations from both.

Schools, strictly speaking — both sit within broadly Latin Christianity but diverge on metaphysics, grace, and the will. We treat them alongside the traditions because the live theological questions they raise cross denominational lines (Reformed Augustinianism, Protestant Thomism, and so on) and deserve their own experts.

A contested question — every tradition claims continuity with the early Church in different ways. The AI presents the historical evidence (liturgy, polity, doctrinal development) and lets you examine the arguments each tradition makes for continuity rather than declaring a winner.

Yes. Pick your tradition and ask for its distinctive doctrines, its characteristic spiritual practices, the authors who shaped it, and the places where it disagrees internally. Deep familiarity with your own tradition is the best foundation for ecumenical conversation.

These are on the roadmap. For now, ask any tradition's expert about them and the AI will present the historical relationship and theological distinctives. Full dedicated experts for smaller traditions ship as the corpus and community support grow.

Ecumenical by design, never flattening. The Creeds (Apostles, Nicene, Chalcedonian) are shared ground. Beyond that, traditions diverge, and TheoSumma shows you the divergence honestly rather than smoothing it into a lowest-common-denominator 'mere Christianity.'

Yes. The free plan covers the theological traditions, systematic theology, the AI experts, and Bible study. Paid plans raise daily limits and add premium features for research-heavy users.
