01Before the library
He began with almost nothing.
Christian Cassarly did not begin inside a university, a technology company, or a great preservation institution. According to Christian Cassarly’s account, accusations from within his family led to criminal allegations and convictions he maintains concerned acts that had nothing to do with him. His former life collapsed. He eventually became homeless.
Christian Cassarly says time, faith, and the work he began doing for God allowed people willing to reason carefully to see him differently. His interpretation is spiritual as well as personal: Christian Cassarly believes the intensity of the resistance was bound to a destiny he had not yet fulfilled.
Before Christian Cassarly could preserve a library, he had to preserve the possibility of his own future.
02The long return
Five years in the markets.
With no institution waiting to finance his vision, Christian Cassarly entered the financial markets. He studied risk, loss, patience, and discipline. Over approximately five years, Christian Cassarly developed into a professional investor and earned the means to regain stability.
The capital was not the destination. Christian Cassarly used it to begin an undertaking larger than his recovery: an operating system and a Christian library built in synchronization, each giving the other purpose.
03Learning the machine
There was one problem: he could not code.
Christian Cassarly had imagined technology he did not yet know how to build. Artificial intelligence became teacher, coding partner, and gateway. With AI-assisted development, Christian Cassarly learned how software was structured, how vast datasets could be searched, and how secure systems could turn an idea into an experience.
Within roughly one year, Christian Cassarly brought Jesus New OS to completion and built the foundation of the Codex alongside it. The man who had lost his physical home was constructing a permanent digital home for books.
04The scattered inheritance
The books existed. The library did not.
Across Harvard collections, HathiTrust, the Text Creation Partnership, and repositories throughout the internet, Christian literature survived in pieces: manuscripts, early printed volumes, institutional scans, specialist datasets, and damaged machine transcriptions.
Christian Cassarly built ways to find Christian works among enormous mixed collections, preserve their lineage, and gather them into a corpus devoted to Christian thought. Like the historical labor by which writings were carried across manuscripts and generations, this was a work of gathering. The comparison concerns preservation—not authority.
Scripture remains unique, and the canon remains closed. Christian Cassarly regards the Codex as testimony to the Bible: the continuing record of authors whose lives and thought were shaped by Christ, and in some cases among the closest literary companions to Scripture.
05The Codex
A vault was not enough.
Christian Cassarly did not want a warehouse of inaccessible files. The Codex now represents approximately 250,000 Christian books and records, and it is climbing rapidly with AI assistance. Christian Cassarly’s stated goal is one million by 2028.
The collection is protected through preservation systems, but Christian Cassarly also opened it to readers at ChristBooks.org. The website works like a public library product catalog: people around the world can discover the Codex, open a book, and begin reading.

06Inside the operating system
Library and machine, built as one.
Jesus New OS is not merely a doorway placed in front of the Codex. Christian Cassarly built the operating system and library in sync so that discovery, reading, preservation, and security could behave as one cohesive experience.
Christian Cassarly describes it as a knowledge-bearing operating system: the Codex supplies the accumulated Christian inheritance, while Jesus New OS supplies the environment through which that inheritance can live. The project presents this union as the first of its kind; that distinction is its stated position rather than an independently audited world record.
The software is available through Apple, placing the experience in the hands of the public rather than behind institutional walls.
07The testimony continues
Two inheritances meant to endure.
Christian Cassarly sees two related fields of spiritual knowledge standing across time: the Bible, and the testimony born in response to the Bible—the books, sermons, histories, meditations, arguments, and witness of Christian authors.
The first is Scripture. The second does not extend the canon; it records humanity’s continuing encounter with it. Christian Cassarly believes restoring that testimony can help people reason together, understand Christ more deeply, and recover wisdom that institutional obscurity nearly removed from public life.
08The Christian conservator
Preservation must end in reading.
Many recovered works carry broken lines, mistaken letters, missing chapters, scanning debris, and damaged typography. Some reach back toward the 1200s. Christian Cassarly intends to retain the source artifact while creating carefully restored reader editions with the ease of a modern Kindle experience.
Christian Cassarly is also the author of 23 Christian books. He knows what a written work costs its author. That makes the next mission personal: not changing the voices of the past, but removing the damage that prevents those voices from being heard.
Originals remain protected. High-confidence repairs can be assisted by machines. Uncertain passages require provenance, caution, and review. That is why Christian Cassarly calls the role a Christian conservator.
09Toward one million
The library is alive because it is growing.
Somewhere online, another Christian volume remains unidentified. Somewhere behind a broken transcription, another author is waiting to speak clearly. Christian Cassarly is still searching, validating, gathering, and building.
The ambition is not merely numerical. Christian Cassarly wants the collection restored until each viable work can enter the Codex reader with dignity. The project describes ChristBooks as the world’s largest dedicated Christian digital library; the collection scale is evolving quickly and that superlative remains a project claim pending independent comparison.
10The future he sees
Knowledge returned to the world.
Christian Cassarly imagines the Codex helping people unify around knowledge of Christ that has been recovered, protected, and made readable. The image is cinematic, but the access is real: readers can enter through ChristBooks.org and Jesus New OS today.
Christian Cassarly believes God assisted him through homelessness, financial rebuilding, technical uncertainty, and the continuing legal resistance he says still surrounds his life. Whatever judgment readers form about that account, the operating system and the gathered collection are the work he places before them.
After the final frame
The story is not over.
Jesus New OS has been completed. The Codex continues to grow. The restoration has begun.
And Christian Cassarly is still building.
Christian Cassarly is now working toward a phone of his own—technology conceived to let people carry the Codex through an experience centered primarily on Christian knowledge, tools, and purpose. It is the next stated chapter, not yet the closing credit.
A man who once had no home built a home for books.
An author of 23 books became the guardian of hundreds of thousands more.
Christian Cassarly is walking the earth now—and the work continues.
The operating system is here. Experience the Codex inside Jesus New OS now.
