David Watson and William Abraham are spot on!
There are at least two ways of looking at Christian orthodoxy. On the one hand, orthodoxy could involve a set of claims that can be used as a litmus test to see who is in and who is out. Orthodoxy then describes a gateway requirement for admission into the life of the church. Unfortunately, orthodoxy has been used in this way many times, but this is actually a secondary use, if not a misuse, of its intended function. A much healthier way of thinking about the orthodox claims of the church is as life-giving resources. These claims are critical not because we need some minimal set of admission requirements, and not simply because these claims delineate our tribe from other tribes, but because knowing the truth about God can lead us more fully into the life of God, and it is within the life of God that true life is to be found.
Wesley knew what so many of us have forgotten today: The set of claims that we make about God will shape the ways in which we view the world around us and will come to bear significantly upon the way we live. We all have a way of looking at the world, but not all ways of looking at the world are equally virtuous or healthy. Not all ways of looking at the world are equally true. The witness of the church through the centuries is that the most virtuous and truest way of looking at the world is through the lens of our creedal faith.
