This is a film from 1941. It was filmed on Easter Sunday at Our Lady of Sorrow's Church in Chicago. The narrator is Fulton J. Sheen. The music alone makes it worth watching. Bishop Sheen's explanation of the Mass is invaluable.
"Slavery ended in medieval Europe only because the church extended its sacraments to all slaves and then managed to impose a ban on the enslavement of Christians (and of Jews). Within the context of medieval Europe, that prohibition was effectively a rule of universal abolition. "— Rodney Stark
