 DATE: In the closing scenes, as the dead are buried at sea, the crew  is saying the Lords Prayer. Given the year, they would be using the  version known by all from The Book of Common Prayer (1662 edition):  "Our Father, which art in heaven..." Instead they say, "Our Father,  who art in heaven..." the first instance of which actually appeared  in the American Book of Common Prayer (1892 Revision). As a ship of  the Kings Navy, the established Anglican Book of Common Prayer  would be the normative source of liturgy and prayer.
