Right from the title, this is not an article on Whitehead and his influences but on process theology and its influences. In the latter sense I reiterate that "theology influenced by Hegel is process theology just as much as that influenced by Alfred North Whitehead." See occurrences on Google Books: 3610 hits, a bit much more than "a presumably scholarly source in the 2013". You might learn something deeper by reading texts such as this one (601 pages, first original edition: 1970).
