Religion can engender feelings of anxiety about the constraints of church doctrine as followers mature into their understandings about life and the world. For Paolo Venticinque, an Italian seminarian working as a Jesuit high school teacher, those constraints don’t cause him to question his faith but to wonder how his faith can work beyond them. When Venticinque is sent to Jerusalem to interview men at a mental health institution, he is on a mission of “brand management,” as his superior, Bishop Giuseppe Malatesta, puts it. A Twitter account that has racked up 2.5 million followers and counting is being run by an unknown poster claiming to be the returned Jesus Christ. The men Paolo interviews have been “afflicted with a psychosis called The Jerusalem Syndrome,” so they’re all considered suspects who might be responsible for the account. While Malatesta deems the tweets a threat to the Catholic Church, Paolo questions the bishop’s assessment, because the posts are preaching compassion and unity. After speaking to the men and sharing his thoughts about his findings with his neighbor, Shirin, his mother, Leonella, and an inspector by the name of Viterbo, things don’t seem to add up. With a deft hand, Parish weaves into this religious thriller facts of historical relevance, sumptuous descriptions of regional foods (and the ritualistic attitudes that go along with them), and an admiring attentiveness in the depictions of his women characters. In the latter part of the book, however, the pacing falls into a less exciting rhythm as the narrative somewhat neatly wraps up loose ends rather than continuing to carry on the heightened sense of intrigue that significantly bolstered the earlier sections. Still, Parish has crafted a prescient and thoughtfully weighty story that reflects on religion’s effect on relationships and communities.
