A study library for the Lutheran Confessions.
The Concord Project presents the Book of Concord as a connected digital library. You can read a creed, move through an article, search a phrase, and return to a saved note without working around a scanned page.
Keep the book close to the work of study
Students, pastors, and church members move between confessions, articles, and Scripture citations. Use the contents panel to see where a passage belongs, then follow the previous and next controls through the document.
Choose a search result to open the paragraph that contains a match. Each saved note, highlight, and bookmark links to its passage, so you can continue a study session after you leave the reader.
Source and scope
The site uses the English text from the 1917 Triglot Concordia. During preparation, the project team removed the printed title page, printed table of contents, running capture headers, and footer URLs. The site retains the confessional wording, document order, headings, paragraph numbers, bracketed readings, citations, and source notes.
The library includes the three ecumenical creeds, the Augsburg Confession and its Apology, the Smalcald Articles, the Treatise on the Power and Primacy of the Pope, both catechisms, both parts of the Formula of Concord, the Catalogue of Testimonies, and the Visitation Articles.

Questions readers often ask
What is The Concord Project?
It is a free digital reading and study library for the Book of Concord, the historic collection of Lutheran confessions.
Which English edition does the library use?
The current text is prepared from the 1917 English Triglot Concordia while preserving its confessional wording, document order, headings, paragraph numbers, citations, and source notes.
Do I need an account to read or take notes?
No. Reading, search, notes, highlights, bookmarks, progress, and display settings work on the device without an account.
Where are my notes and highlights stored?
Guest study data stays in your browser. If account synchronization is available and you sign in, the account flow explains which data can be synchronized.
Can I link directly to a confession or paragraph?
Yes. Documents and sections have stable pages, and paragraph links let you return to or share a precise place in the text.
Is The Concord Project the same as TrinityLibrary?
No. The Concord Project is dedicated to the Lutheran Confessions. TrinityLibrary is the wider Christian primary-source archive in the TrinityApologetics ecosystem.
