Note: to make this Creed more readable, some qualifiers have been omitted. So "God" signifies God/ultimate reality/final truth, not just a personal divinity. And "religion" signifies religion/spiritual path/philosophy, not just a mainstream theology.
There is no objective proof that any religion knows the truth about God. If there were such proof, most people on Earth would have converted to that faith long ago and all scientists would be believers.
Spirituality thus is an individual affair. Proof of any metaphysical realities that exist will be subjective, not demonstrable to others.
Every person has the right to pursue their own spiritual quest without interference, so long as he or she doesn't interfere with the rights of others.
Since the veracity of each and every religion is unprovable, equally unprovable are the moral and ethical tenets derived from any and all religious teachings.
Thus morality also is an individual affair. There are no absolute laws of right and wrong as there are absolute laws of physics. Subjectivity rules in ethics.
Individual ethical decisions may be formed into a collective codification of societal norms, or laws. These are purely human, not divine.
Science is the surest means of finding truth. Theory, experiment, analysis of data: such are the tools of science, whether directed toward knowing material or immaterial reality.
Religious teachings are hypotheses to be confirmed through individual research. As such, they must not be taken as gospel truth by adherents of a particular faith.
Religious doubters, skeptics, and heretics should be honored for their efforts to assure that unproven assertions about God are not put forward as solid truth.
Every adherent of a particular religion should say to himself or herself,"I could be wrong." If he or she won't do this, other people can say it for them: "You could be wrong."
This creedless creed of the Church of the Churchless also could be wrong. It needs to be reexamined and revised regularly.
Death provides the final answers (if only momentarily). The spiritual quest is to get answers ahead of time. But the big question is, "What are the questions?"
