The 53 volumes of Christian councils throughout Church history, previously only in Greek and Latin, have just now been AI translated into English at The Faith Received.

These are from the standard older edition that goes up to 1902, edited Mansi.  When most people think they have read what a council said in some book, it is actually only a sliver of that council’s dogmatic decrees.  Mansi contains not only all the dogmatic decrees, but all their other, sometimes voluminous, written productions as well, often with scholarly historical introductions and other material.

The AI volumes have been linked next to the Latin volumes in numeric, chronological order on our page:

For an excellent guide to these volumes and the AI translations, with more ways to navigate and search them, see The Faith Received.

Per Stiven Peter, a main creator of The Faith Received, the site no longer has many of the tech and translation issues it did when it was released.  It continues to get better on these fronts and is adding volumes quickly.
