Congregations seeking to transform are willing to deal with the sacred cows in their midst. Bill Easum wrote a book some years ago entitled Sacred Cows Make Gourmet Burgers. In it he called on congregations to move dramatically beyond those cultural practices they have held up as sacred that keep them from making progress.
Queen and Davis in Hopeful Imagination  put it this way: “Most traditions are not bad. If they were, it would be easy to let go of them. What is difficult is letting go of something good in order to make room for something great.”
