When Judge Amy Coney Barrett came before the Senate Judiciary Committee for her nomination to the court of appeals, Senator Diane Feinstein generated considerable controversy when she said to Barrett: “The dogma lives loudly in you.” … Under our Constitution, Senator Feinstein’s statement crossed the line. Ours was the first Constitution in history to provide that “no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States.” Although Feinstein did not explicitly impose a religious test, she suggested that personal religious views — which she called dogma — might disqualify a nominee from being confirmed. That would clearly be unconstitutional.
Religious tests have no place in America. But what does have a place in the confirmation process are questions about whether a nominee will put faith before the Constitution and refuse to apply the Constitution if it conflicts with his or her faith. That issue would be true of any nominee regardless of their faith or faithlessness. President John F. Kennedy assured us that his Catholicism would not determine the nation’s policy. Justice Antonin Scalia said the same about his Catholicism and his jurisprudence.
One’s religion is a private matter, but one’s judicial philosophy is highly relevant in the confirmation process… Let us hope the Senate handles this nomination better than they have handled other recent nominations.
When Judge Amy Coney Barrett came before the Senate Committee on the Judiciary for her nomination to the Court of Appeals for the Seventh Circuit, Senator Diane Feinstein generated considerable controversy when she said to Barrett: “The dogma lives loudly in you.” This was a reference to Barrett’s deep Catholic faith. Under our Constitution, Senator Feinstein’s statement crossed the line. Ours was the first Constitution in history to provide that “no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States.” Although Feinstein did not explicitly impose a religious test, she suggested that personal religious views — which she called dogma — might disqualify a nominee from being confirmed.
