So says William FitzGerald:
In his book, FitzGerald draws upon contributions to rhetorical theory from Kenneth Burke along with a broad range of classical and contemporary perspectives on audience, address, speech acts, and modes of performance across all religious traditions and historical eras.
He says prayer is a phenomenon of both cognitive and social memory. It is cognitive because prayer is learned through performance, including memorization, and it is social because it is handed down through textual and oral transmission as a shared resource of a spiritual community.
Saving this for later.
