Decanon

Every book of the Bible, deconstructed — bite-sized sections flagging the violence, contradictions, and history you were told to overlook. Just citations.

Decanon is a critical study companion to all 66 books of the Protestant Bible. Every book is broken into short, readable sections, each annotated with what mainstream academic biblical scholarship has documented about the text.

Unlike a devotional Bible app, decanon takes a scholarly perspective. It surfaces what the academic study of religion has been teaching for over a century: the Documentary Hypothesis, archaeology of the ancient Near East, the dating of biblical texts, internal textual contradictions, and the ethical and historical questions modern readers reasonably bring to ancient literature.

The app is designed for religious-studies students, comparative-religion readers, people exploring critical biblical scholarship for the first time, and anyone who wants to engage with the Bible as carefully as they would any other ancient text.

EVERY BOOK, EVERY FLAG All 66 books of the Protestant canon. Each flagged section is tagged with one or more of 11 issue categories:

• Violence • Misogyny • Slavery • Anti-LGBTQ teaching • Harm to children • Conflicts with modern science • Internal contradiction • Historical error • Racism and ethnocentrism • Moral issues • Logical issues

Tap any flag to read the full annotation, with a specific verse reference you can look up in any Bible.

WHAT'S INSIDE • Overview and critical context for every book • 100+ flagged sections across the canon • Filter chips — focus on a single issue type across all 66 books • Full-text search across books, sections, and annotations • Editorial dark aesthetic with serif typography, designed for long-form reading • Three iOS 18 icon appearances: Light, Dark, and Tinted

SOURCES Content draws on standard reference works in the academic study of religion. Among the core sources informing the app's commentary: Bart D. Ehrman (UNC Chapel Hill), Richard Elliott Friedman (UC San Diego), Israel Finkelstein and Neil Asher Silberman, and the broader historical-critical scholarly tradition. Every flag includes a specific verse reference so readers can independently verify any claim.

The same material covered in decanon is taught in undergraduate religion courses at major U.S. universities.
