Reflections on James MacDonald, TD Jakes, and the Trinity

This might have been the issue behind DeYoung's post on the Trinity yesterday. Driscoll goes into more detail: Reflections on James MacDonald, TD Jakes, and the Trinity | Pastor Mark:

The debate land mine that MacDonald has stepped on is in large part over the word “manifestations”. In its simplest form, this is the language of Modalism. In classic Modalism there is one God who manifests Himself in three ways (Father, Son, and Spirit) but is not three distinct persons. By this it’s meant that God is successively Father, Son, and Spirit but not simultaneously Father, Son, and Spirit. Think of it in terms of someone who is an actor playing three different roles in a play with wardrobe changes between scenes.
