Primitive men had everything to fear from the unknown, and they developed a system of myths to allow them to accept their relationship to the world around them. The fundamental thesis of the Agnostic Church is that it is time for intelligent individuals to declare they no longer need myths to protect them from the unknown. We can now look at the unknown as a challenge to be overcome, not as a fear to be suppressed. Accordingly, we can discard all myths and rely upon scientific facts of the past, present, and future for the foundations of our belief system. We must remember, however, that we do not worship science.
Science is only a tool.
We refuse to make the mistake of defining the answer before we do the research. We have learned much in the last 1000 years. Thus, we are not in a position to define the nature of God. Most philosophers merely re-state some expression of conventional wisdom, even if they appear to be offering an inspiring insight. Mill is no exception.
