Bishop Robinson called us to the task almost four decades ago in Honest to God, and for all the confusion he may raise, Bishop Spong calls us to this task today in Why the Church Must Change or Die. Regardless of what we may think, these writers speak for and to a growing number of people. Thus there must be a rebirth of the images, a move beyond the impasse at which theological understandings currently leave us. The church's vocabulary contains many in-words. We place unnecessary stumbling blocks in people's paths when we expect them to know the language game we are playing.
Many people have no background in the Christian faith to fall back upon for definitions of terms.
They consider our terminology to be mystification, not mystery. Every preacher might offer definitions of terms used within the sermon in the interest of clarity, on one hand, and hospitality on the other. The language of the church is not a code, nor is it static, and hence we must engage in re-definition every time out. Preaching is the harbinger of change, in this case. Furthermore, in this post-modern era, all the senses are used for understanding.
