BORED by those endless replays of the Rev. Jeremiah Wright? If so, go directly to YouTube, search for “John Hagee Roman Church Hitler,” and be recharged by a fresh jolt of clerical jive.

What you’ll find is a white televangelist, the Rev. John Hagee, lecturing in front of an enormous diorama. Wielding a pointer, he pokes at the image of a woman with Pamela Anderson-sized breasts, her hand raising a golden chalice. The woman is “the Great Whore,” Mr. Hagee explains, and she is drinking “the blood of the Jewish people.” That’s because the Great Whore represents “the Roman Church,” which, in his view, has thirsted for Jewish blood throughout history, from the Crusades to the Holocaust.

Mr. Hagee is not a fringe kook but the pastor of a Texas megachurch. On Feb. 27, he stood with John McCain and endorsed him over the religious conservatives’ favorite, Mike Huckabee, who was then still in the race.
