An ominous hymn
A Navy Hymn named “Eternal Father, Strong to Save” is being sung by the congregation in the church during a Sunday morning scenario. It is the most beautiful hymn. Rose can be seen singing “for those in peril on the sea” in a close-up. Despite the fact that the song is featured in the film, there is no proof that it was performed on the Titanic.
Indeed, the hymn was absent from the customary Sunday onboard worship, according to letters received later from two survivors. According to The Washington Post, the song was later repeated that day during a hymn sing among second-class passengers. Not only that, but the song they performed in the film was composed for navy aviators in 1937—a full 15 years after the tragedy.
