About this Encyclopaedia

The Encyclopaedia of the Holy Spirit gathers the documented wonders of God — the miracles of Scripture, the signs worked through the saints, the apparitions of Our Lady, the Eucharistic miracles studied by science, the interventions of guardian angels, and the defeat of every power that sets itself against Heaven.

It continues the work begun by St. Carlo Acutis (1991–2006), who built an online exhibition of the world's Eucharistic miracles before his death at fifteen, and who was canonized in 2025. What he began with one catalogue, this encyclopaedia extends to the whole history of salvation — in nineteen languages: the most spoken tongues on earth, and the older tongues of the lands where these things happened.

Each story is told in the first person by the Holy Spirit, and each is followed by the Record: the scriptural citations, dates, investigations, and rulings of the Church that anchor it in history. The narrative voice is a literary devotion; the Record is fact.

Readers are invited to share their own testimonies, which are moderated before publication.

The Encyclopaedia of the Holy Spirit is an initiative of Arvor (arvor.co), offered freely as a spiritual gift, with no commercial purpose. Every story is researched and anchored in the Record with its sources, the translations are reviewed by people, and the testimonies readers send are moderated before they appear.
