Hundreds of early Christian texts have never been translated into English. Theosis Library is changing that — one text at a time.
The project name Theosis (θεωσις) comes from the Greek theological concept of divinization — the idea that humanity is called to participate in the divine nature. This concept sits at the heart of the earliest Christian debates: is divinity the exclusive property of Christ, or is it a spark within all beings waiting to be awakened? The texts in this library illuminate both sides of that ancient question.
For centuries, the writings of the Church Fathers — and the Gnostic texts they argued against — have been locked away in Greek and Latin, accessible only to specialists. Many have never appeared in English at all. Theosis Library brings these texts into modern English for the first time, with scholarly annotation and full transparency about methodology.
Each translation is produced by a classicist using AI-assisted drafting, then reviewed and corrected against the original Latin and Greek, with the translator’s own scholarly annotations. Every published text links back to the original source so readers and scholars can verify the work.
