When Martin Scorsese was a child growing up in New York's Little Italy, he would gaze up at the figures he saw around St Patrick's Old Cathedral. “Who are these people? What is a saint?” Scorsese recalls. “The minute I walk out the door of the cathedral and I don’t see any saints.

I saw people trying to behave well within a world that was very primal and oppressed by organized crime. As a child, you wonder about the saints: Are they human?” For decades, Scorsese has pondered a project dedicated to the saints. Now, he's finally realized it in “Martin Scorsese Presents: The Saints,” an eight-part docudrama series debuting Sunday on Fox Nation, the streaming service from Fox News Media.

The one-hour episodes, written by Kent Jones and directed by Matti Leshem and Elizabeth Chomko, each chronicle a saint: Joan of Arc, Francis of Assisi, John the Baptist, Thomas Becket, Mary Magdalene, Moses the Black, Sebastian and Maximillian Kolbe. Joan of Arc kicks off the series on Sunday, with three weekly installments to follow; the last four will stream closer to Easter next year. In naturalistic reenactments followed by brief Scorsese-led discussions with experts, “The Saints” emphasizes that, yes, the saints were very human.

They were flawed, imperfect people, which, to Scorsese, only heightens their great sacrifices and gestures of compassion. The Polish priest Kolbe, for example, helped spread antisemitism before, during WWII, sheltering Jews and, ultimately, voluntee.
