Memo To My Fellow Catholics: This is how we know we are right.

I've been saying it for decades: The perversion that manifests itself as anti-Catholicism is the only publicly acceptable prejudice in the good ol' USA.

Still don't believe me, do you? Notice how Holy Mother Church is attacked by both sides of the establishment aisle. What is the common denominator? Modernity is rationalized sexual misbehavior.

Check it out for yourself, kiddies. What do Newt Gingrich, Ronald Reagan, Rush Limbaugh, Ted Kennedy, and Barney Frank have in common?

They should be ashamed. We should be ashamed. We have not progressed much in 45 years it seems, and we appear to be traveling in the wrong direction.

Article VI of the Constitution prohibits a religious test from being imposed on nominees to public office. The clause was motivated by the experience of Catholics in the Maryland colony and Baptists in Virginia who had been the targets of Great Britain's two Test Acts. These infamous laws of intolerance sought to prevent anyone who did not belong to the Church of England from holding public office. The Test Acts did not say that Catholics could not hold office; the bigotry was more subtle. Officials questioned would-be public servants to determine whether they believed in particular tenets of the Catholic faith.

While questioning John Roberts on Tuesday, Judiciary Committee chairman Arlen Specter asked: "Would you say that your views are the same as those expressed by John Kennedy when he was a candidate, and he spoke to the Greater Houston Ministerial Association in September of 1960: 'I do not speak for my church on public matters, and the church does not speak for me.' "

This is about Catholicism, not John Roberts. We'll never know what kind of Catholic he is, though we will be able to make some educated guesses. We'll find out soon enough what kind of judge he is.

Hours later, Sen. Dianne Feinstein of California made it worse: "In 1960, there was much debate about President John F. Kennedy's faith and what role Catholicism would play in his administration. At that time, he pledged to address the issues of conscience out of a focus on the national interests, not out of adherence to the dictates of one's religion. . . . My question is: Do you?"

How insulting. How offensive. How invidiously ignorant to question someone like Judge Roberts with such apparent presumption and disdain for the religion he practices. The JFK question is not just the camel's nose of religious intolerance; it is the whole smelly camel.

Outrage over this line of questioning was ecumenical. In his new blog, Jewdicious.blogspot.com, Jeff Ballabon of the Center for Jewish Values posted this from the Senate's hallways:

I mean how grotesque is it that the Left feels free to indulge openly in half-century-old religious prejudice? This is not some crazy person standing outside with a rusty hanger--it is a United States Senator in her official capacity on national television. And this is no off-the-cuff blurt--these questions are excruciatingly researched and drafted and worded and reviewed and approved and choreographed by teams of liberal lawyers and advisors both on her staff and off. She--the senator who keeps harping at this hearing that her concern is the protection of people of faith--thinks an obnoxious question born of religious bigotry is legitimate because it was posed in 1960?

Non-Catholic Christians also spoke up. Wendy Wright of Concerned Women for America issued this statement:

It is precisely this kind of anti-Christian religious litmus test that many Americans find deeply offensive. . . . Feinstein is dipping her toe into the very ugly, muddy waters of religious bigotry. America's Founding Fathers considered religious beliefs to be an asset, even essential to public officeholders. Sadly, Sen. Feinstein apparently believes the opposite of those wise men to whom we owe gratitude for our free and strong country.

Catholic leaders were stunned. Austin Ruse of the Culture of Life Foundation:

Senator Feinstein invoked those terrible debates in America about whether Catholics could have a role in the public square. Apparently Senator Feinstein agrees with those who feared faithful Catholics in public office. Senator Feinstein's questioning is an unconscionable dredging up of a dark time in America. . . . She owes Judge Roberts and all Americans an apology.

By Wednesday morning, the Catholic League's Bill Donohue and the Catholic think tank Fidelis reacted also, and to their credit took both the Republican and the Democrat to task. Mr. Donohue, the feisty veteran, called the two senators' questions a "dirty road" and a "disgrace." Fidelis's president, Joe Cella, wrote the two senators thoughtfully worded letters asking for their apology and to refrain from further offense. But Mr. Cella drew distinctions:

Of the two Senators remarks, Senator Feinstein's were the most disturbing because she referred to the Catholic faith as 'dictates.' It shows her callous insensitivity and ignorance of the teachings of the Catholic faith. Forty-five years since JFK faced similar questions about his Catholic faith, we continue to have Senators asking questions about the apparent conflict between their Catholic faith and public service in this country. It is unfortunate that the issue of his religious faith arose. This question has no place or bearing on his confirmation.

The JFK question has no place in a Senate confirmation process. The Constitution says so. As I noted in an earlier column new secularist bigotry has found a home in the Senate Judiciary Committee. I was not the first to say so. In July 2003, the Most Rev. Charles Chaput, Archbishop of Denver, reacted to the growing evidence of a religious test in the Senate: "Many people already believe that a new kind of religious discrimination is very welcome at the Capitol, even among elected officials who claim to be Catholic. Some things change, and some things don't. The bias against 'papism' is alive and well in America. It just has a different address."

Catholic archbishop's voice in politics is a rare enough thing, but it was not alone. Representing more than 1,000 synagogues, the Union of Orthodox Jewish Congregations wrote this letter to the Senate Judiciary Committee a few days earlier:

"As a community of religious believers committed to full engagement with modern American society, we are deeply troubled by those who have implied that a person of faith cannot serve in a high level government post that may raise issues at odds with his or her personal beliefs."

Now, two years later, the situation is worse. Anti-Semitism marred the confirmation battles of associate justices Abe Fortas, Louis Brandeis, and Benjamin Cardozo, but it was unpronounced and hidden. John Roberts will be only the 11th Catholic (out of 109 justices) to serve on the Supreme Court in its 215-year history. But his confirmation may be a historic first. It marks the introduction, on the record, of a constitutionally prohibited religious test for a Supreme Court nominee. We are going in the wrong direction.

Mr. Miranda, former counsel to Senate Majority Leader Bill Frist, is founder and chairman of the Third Branch Conference, a coalition of grassroots organizations following judicial issues. His column will appear daily during the Roberts hearings.
