Including but not limited to branding Ebert as a heretic, coercing him into joining the artificial god plan, and attempting multiple times to forcibly advance the fusion of the Great Saint Mother and Erin during the plan's progress.
Even the item letter that triggered Wu Chang's hidden side quest was written by Archbishop Gelman, aiming to confirm Jermaine Count's progress with Ebert and to reap the benefits through the "Blessing of the Great Saint Mother" necklace.
The involvement of Archbishop Gelman likely indicates that the projection of the Great Saint Mother was also participating in the operation.
