Nothing must be held sacred. Question everything. God is not great, Jesus is not your lord, you are not disciples of any charismatic prophet. You are all human beings who must make your way through your life by thinking and learning, and you have the job of advancing humanity's knowledge by winnowing out the errors of past generations and finding deeper understanding of reality. You will not find wisdom in rituals and sacraments and dogma, which build only self-satisfied ignorance, but you can find truth by looking at your world with fresh eyes and a questioning mind.
