: The team investigates survivors of a disaster who claim a woman in white carrying a lamb led them to safety. While the Church initially hopes this is a miracle linked to a dead white Sicilian nun, the atmosphere shifts when a Black survivor describes the angel as a Black woman.

A core theme of the episode is the "whitewashing" of religious imagery and the resulting institutional discomfort when that imagery is challenged.

: To save Sister Andrea from forced retirement, David uses the Church's own political sensibilities against them. He claims to see the same "blasphemous" demons as she does, forcing the tribunal into a corner: if they fire her, they must also fire one of their few newly ordained Black priests.

The episode features the resolution of the tribunal against Sister Andrea, whose sanity and career are under threat due to her visions.

: The Monsignor expresses visible discomfort and a desire to "move on" from the case once race is involved, highlighting a "poison" or deep-seated bias within the Church leadership.

: Father David Acosta grapples with the realization that his own visions might be hallucinations informed by traditional Renaissance art, where angels are depicted as white and demons as dark-skinned. The Trial of Sister Andrea

While David and Andrea fight for their place in the Church, other characters descend further into darkness.
