In Brave New World, religion is seen mainly in Chapter 5, when Bernard Marx attends the Solidarity Service. This service helps create community, identity and stability. The service helps the people who attend it to identify with one another, thus forming a community. The lyrics of the song are all about identifying with one another:
Ford, we are twelve; oh, make us one,
Like drops within the Social River,
Oh, make us now together run
As swiftly as thy shining Flivver.
This song combines with their communal hallucination of hearing and seeing the “Greater Being and with the orgy to create a sense that they are all together in one community and that they should identify with that community. When they come to identify with the community so strongly, and when they have the emotional catharsis of the ceremony, they help to make their society more stable, thus fulfilling the motto.
