A Traditional Catholic Latin Mass filmed on Easter Sunday in 1940 at Our Lady of Sorrows church in Chicago. The film presents the ceremonies of the Missa Solemnis or Solemn High Mass in full detail with narration by then-Mgr. Fulton J. Sheen. Celebrated by Rev. J. R. Keane of the Order of Servites (hence the white habits and cowls), the ceremonies are accompanied by a full polyphonic choir, orchestra, and fifty Gregorian Chanters.
While this is an older video of the Traditional Latin Mass, it is a good educational video that is still relevant even today. The attention to detail in the ceremonies is impressive. Notice, for example, how the servers and priests always take great care to move in order. Notice too that the servers are all almost identical in height. The Ordinary of the Mass, composed by Rev. Edwin V. Hoover, while pleasant in places, is very much a reflection of its time. The Proper on the other hand is timeless and sung admirably by a healthy throng of Seminarians from Mundelein, Illinois.
