Some time ago I found this video, "Captains in HIS Army", on the Archdiocese of St. Louis Office of Vocations website and asked permission to post it here. You can find this video (higher resolution), along with others, on this page of their website.
The video was produced in the 1940's by the Serra Club of St. Louis in order to promote and encourage vocations to the Priesthood. If you have 26 minutes, I HIGHLY recommend that you watch it. It is a period video, meaning that the music and narration is "nostalgic", but it is a fascinating glimpse into the world of vocations and seminary formation (for that matter the Church) of the 1940's. The ordinations are quite wonderful to see.
A special thank you to the Archdiocese of St. Louis Office of Vocations for allowing me to post a copy of the video here.
