It's just a new word for an old belief. Christianity goes by a new name, Jesusology, sometimes called Christology, but it's the same thing. Used and made popular by Dr. S. Ogden, gives people new motivation to study the life and teachings of Jesus Christ.
If it gets people to study and think, it's a good thing. And it's a good time to see that The Bible is not outdated but is as relevent as ever.
