The next time believers tell you that 'separation of church and state' does not appear in our founding document, tell them to stop using the word 'trinity.' The word 'trinity' appears nowhere in the bible. Neither does Rapture, or Second Coming, or Original Sin. If they are still unfazed (or unphrased), by this, then add Omniscience, Omnipresence, Supernatural,Transcendence, Afterlife, Deity, Divinity, Theology, Monotheism, Missionary, Immaculate Conception, Christmas, Christianity, Evangelical, Fundamentalist, Methodist, Catholic, Pope, Cardinal, Catechism, Purgatory, Penance, Transubstantiation, Excommunication, Dogma, Chastity, Unpardonable Sin, Infallibility, Inerrancy, Incarnation, Epiphany, Sermon, Eucharist, the Lord's Prayer, Good Friday, Doubting Thomas, Advent, Sunday School, Dead Sea, Golden Rule, Moral, Morality, Ethics, Patriotism, Education, Atheism, Apostasy, Conservative (Liberal is in), Capital Punishment, Monogamy, Abortion, Pornography, Homosexual, Lesbian, Fairness, Logic, Republic, Democracy, Capitalism, Funeral, Decalogue, or Bible.

I have something to say to the religionist who feels atheists never say anything positive: You are an intelligent human being. Your life is valuable for its own sake. You are not second-class in the universe, deriving meaning and purpose from some other mind. You are not inherently evil—you are inherently human, possessing the positive rational potential to help make this a world of morality, peace and joy. Trust yourself.

You believe in a book that has talking animals, wizards, witches, demons, sticks turning into snakes, food falling from the sky, people walking on water, and all sorts of magical, absurd and primitive stories, and you say that we are the ones that need help?

People are invariably surprised to hear me say I am both an atheist and an agnostic, as if this somehow weakens my certainty. I usually reply with a question like, 'Well, are you a Republican or an American?' The two words serve different concepts and are not mutually exclusive. Agnosticism addresses knowledge; atheism addresses belief. The agnostic says, 'I don't have a knowledge that God exists.' The atheist says, 'I don't have a belief that God exists.' You can say both things at the same time. Some agnostics are atheistic and some are theistic.
