In the feature-length documentary "The First Hymn," Australian historian John Dickson guides viewers on a journey from the ancient ruins of Oxyrhynchus to the modern resurrection of a 2,000-year-old Christian hymn. Along the way, acclaimed composers Chris Tomlin and Ben Fielding collaborate with Stephanie Boonstra to transform the papyrus scrap into a contemporary worship piece, culminating in a live concert performance that brings this lost melody back to life.
