Scientists do not join hands every Sunday and sing "Yes gravity is real! I know
gravity is real! I will have faith! I believe in my heart that what goes up, up, up must come down, down, down. Amen!" If they did, we would think they were pretty insecure about the concept.
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.
Faith is a cop-out. If the only way you can accept an assertion is by faith, then you are conceding that it can't be taken on its own merits. It is intellectual bankruptcy.
