The Right Reverend Richard Chartres warned that the biggest problem for the Church was that it was "lacking in distinction" and not its attitude to gay people and women.
Writing a blog on Philosophy for Life, the Bishop said the Church was struggling to offer meaning in the current world.
He said: "The real trouble with the Church is not that it has retrograde social attitudes or hasn't embraced the emancipation of women, it's that it's spiritual incredible.
"It's just as shallow as the rest of us. That's the real truth, and that's why people are fascinated by other ways which have remained less disturbed by the Gospel that really grips this society, which is that there should be no constraint on individual consumer choice in goods or morals.
"That's the very opposite of the truth. Autonomy is the story of the fall, not redemption. The Church has accommodated itself so much and is so lacking in distinction."
