The best Christian theology AI translation storehouse and research tool has been released and is free: The Faith Received at Mere Orthodoxy.

12,500+ works (1,500+ authors) from the Early, Medieval and Reformation Churches, inclusive of various traditions such as Reformed, Lutheran and Roman Catholic.  Thousands of volumes are now in English that were before locked behind other languages.

It has sophisticated features and the database is full-text searchable, as is every text.  One can search within traditions, authors, etc.

The Latin (etc.) and English can be put in parallel column, often along with the PDF page scans.

One can find where any Bible verse is quoted throughout the whole database.  If you look up a Bible passage, you can easily view any of the many available commentaries throughout Church history on it.

A topical search will bring up every relevant work on that topic in the database through Church history.

One can AI query the whole database, with stunning results.

The tool provides visual maps of the sources a given work or author cites, and who cites that work or author.

The whole is a smaller Post-Reformation Digital Library, but in English and better!  A huge thank you to Stiven Peter, an RTS student in NYC, and the others who have made this available!
