The ChristBooks story
The Impossible
Library.
Christian literature survived for centuries. But it had not survived in one place.
Begin the storyThe scattered inheritance
A library hidden
across the internet.
Across the internet, generations of Christian thought lay scattered among institutional archives, aging scans, obscure repositories, and enormous datasets containing secular, non-Christian, and anti-Christian works.
Some books could be found only by researchers or programmers. Others were technically available but remained nearly invisible to the ordinary reader. They had survived—but not yet as one discoverable, readable Christian library.
A door opens
Files became available.
A library did not.
In June 2025, Harvard released nearly one million digitized public-domain volumes as a dataset intended primarily for artificial-intelligence research and development. It was one extraordinary opening among collections across the internet.
But releasing millions of files is not the same as restoring a library to its readers. The Christian works still had to be found, identified, separated, verified, organized, and given a home.
Making knowledge available as data was the beginning—not the destination.
Learning to build
Christian learned to code
to make it possible.
Christian Cassarly saw what these scattered collections could become. He was not backed by a great institution. Through rejection, hardship, and incredible odds, he learned how to code so he could undertake the work himself.
He built systems to search across the internet, recover Christian works from vast mixed collections, and gather them into a corpus devoted wholly to Christian literature and thought.
The Codex
What was scattered
became one corpus.
The recovered works became the Codex: a dedicated place for Christian literature, separated from the surrounding material without rewriting the substance of the historical texts.
Through the ChristBooks public catalog and online reader, the works are no longer merely scans, records, or machine-readable data. They are books again—discoverable, readable, and open to the public.
The marks of the journey remain. Some editions carry imperfect scans, damaged pages, and institutional transcriptions inherited from works reaching back as far as the 1300s. ChristBooks preserves their provenance honestly while continuing to improve their presentation.
An unforgettable home
Preservation deserved
an experience.
Christian did not want these books hidden inside another database. He wanted entering the library to feel unforgettable—like stepping into a world made for knowledge, faith, discovery, and wonder.
So while building the Codex, he built an operating system around it: Jesus New OS. The Codex became a living library experience where centuries of Christian wisdom could be explored, carried, and encountered anew.
What was scattered has been gathered.
What was buried has been brought into the light.
What existed only as data has become a library.
Against extraordinary odds, Christian built a pure place for the Christian written inheritance—protected within the Codex and preserved for generations still to come.
This is ChristBooks:
the impossible library, made real.
