Labels have always been useful in religious dialogue, not just in Christianity, and long before Christianity. For instance, I find book reviews to be useless to me, unless I know the theological bias of the author of the review. I can illustrate this point further if I state that I am an evangelical conservative. Now everyone has a more certain expectation of where I am coming from in whatever follows. The Presiding Bishop's Year of Jubilee is to allow the Holy Spirit to work in the church and help us discern the mind of Christ.
All truth is pluriform and has many facets.
If we are talking about the color of the sky and one person says it is blue and another person says it is gray, I can understand that compromise, by agreeing that the sky is blue-gray, can be a good thing. But, if one person says two plus two equals four and another person says two plus two equals six, I do not understand how it is a good compromise to say two plus two equals five. I get into this with my wife all the time. In 25 years of marriage I admit great susceptibility to this criticism. That means one of us is wrong.
