“There should be no government intrusion in the pulpit,” said the Rev. James Garlow, senior pastor at Skyline Church in La Mesa, Calif., who led preachers in the battle to pass California’s Proposition 8, which banned same-sex marriage. “The freedom of speech and the freedom of religion promised under the First Amendment means pastors have full authority to say what they want to say.”

Yeah, that's fine. Just as long as you pay taxes like the rest of us, Jim.
