Once upon a time, years before we came to the city that’s Not Officially Toronto But Come On, It’s Toronto, a woman had two children. As a fugitive from a dangerous secret organization, she had to give them up. One, she decided, to the church, and one to the state. This is the origin story for the two primary protagonists of Orphan Black. Sarah Manning went into foster care, while her sestra Helena went to an orphanage run by nuns in Ukraine.
Helena gets indoctrinated into the Proletheans, an ambiguously Christian sect that serves as one of the major antagonists in the series. The religious motifs around the Proletheans make them terrifying, both with Helena as their assassin and as their prisoner. However, the show misses an opportunity to really dig into the theology of the Proletheans and doesn’t truly engage with any number of religious objections to the biotechnology the show presents as being in our immediate future.
