Suspicion raised by the Neo-orthodox movement concerning Schleiermacher's theological enterprise continues to cast its shadow. Karl Barth framed this suspicion perspicaciously in terms of an “either/or” in his “Concluding Unscientific Postscript on Schleiermacher”:
Is Schleiermacher's enterprise concerned (a) necessarily, intrinsically, and authentically with a Christian theology oriented toward worship, preaching, instruction, and pastoral care? Does it only accidentally, extrinsically, and inauthentically wear the dress of a philosophy accommodated to the person of his time…? Or is his enterprise concerned (b) primarily, intrinsically, and authentically with a philosophy…indifferent as to Christianity and which would have wrapped itself only accidentally, extrinsically, and inauthentically in the garments of a particular theology, which here happens to be Christian?
