There's currently quite a bit of discussion around my church, the Common Table, regarding issues of belief and unbelief. These are exactly the sorts of things that churches ought to be discussing (as opposed to not discussing them in a quietly unhappy manner), so this is a healthy thing, I suppose.
Beliefs: We believe our doctrine is adequately encompassed in the Nicene Creed. This is the guiding compass we will follow as a church, while still providing the freedom for members of the church to question and explore matters of faith openly.
Mystery: God is big and we will never be able to fully understand Him. We are not afraid of unanswerable questions. We also believe that God can be experienced through the sacraments and that He works to reveal himself through the arts.
Community: The Common Table exists only in the relationships among its members. We desire to foster a community where people are both accepted completely and encouraged to become more like Christ. We recognize there is tension between those two concepts of acceptance and accountability.
[Paul] Tillich writes of three anxieties (that are simply different ways in which nonbeing makes its absence felt). There is the anxiety of fate which, at its most extreme, is encountered in a despair that we face death. Then there is the anxiety of emptiness (where we experience our various projects as unfulfilling) that can degenerate into the despair of total meaninglessness. And finally there is the anxiety of guilt (where we feel that we fall short of our own being). An anxiety that, at its most all encompassing, is felt in the despair of condemnation.
Tillich questions the idea that the way of Christ provides religious answers to our existential questions. Rather he attempts to show that Christ invites us to participate in a way of being that enables us to live beneath the shadow of these questions. Joyously embracing life while fully acknowledging their presence. Living in such a way that they are deprived of their weight and sting. In doing this he points to the possibility of a God arising from the ashes of the death of the religious God. A God that can be described as the source of our ability to live fully in the midst of our existential doubts.
