The theme of unity is again in the foreground.

This chapter starts with an exploration of the reason for and mechanism of unity: love. This emphasis is expressed explicitly through some wonderful verses, and also poetically through a pattern of 7 that culminates with God our father of all, "who is over all, in all, and living through all." We are intrigued by the role that teaching and doctrine plays (and specifically does not play) in all of this.
