You claim #3 and then approvingly cite a quote that is all #1 & #2.
Why don't you exercise your creative genius and make up a new term. The one you are using is already taken. And by minds much better than yours, namely, the Niebhur's.
PS At least you responded which is more than I can say for bcspace.
I can see at this point that having a serious critical discussion with you may turn out to be a consternating exercise in futility (as is so often the case around here), but I'll just reiterate what I tried to point out above just in case I'm mistaken on that score.
My own definition of Neo-Orthodoxy was:
...a varied yet consistent syncretic blending of contemporary secular concepts, ideas, attitudes, and cultural fashions with the Church with the intention of a gradual displacement of key traditional gospel concepts/standards by contemporary (primarily post-sixties) cultural, social, ideological and political doctrines regarding the same questions of the human condition the gospel grapples with within its own doctrinal and philosophical framework.
Its a syncretic intermingling and integration of the surrounding secular culture with the Church (under the rubric of "tolerance," and "inclusiveness" etc.) while attempting to retain certain aspects of LDS culture and broad values (hence the term cultural Mormon) within the generally secularized superstructure (for example, retaining the LDS idea of the importance of the family, while redefining the concept of "family" to fit contemporary secular liberal ideological doctrines of moral/social neutrality in matters of human sexuality and gender role).
I italicized Midgelys basic analysis of White's core thesis regarding modernity and the Church to point out the similarities between Midgley's understanding of Neo-Orthodoxy and mine:
He also assumes that believers ought to reach an accommodation with modernity by adopting its assumptions and reflecting its values.
You asked for a definition, and I gave you an extensive one.
