‘Quite a shock’: The priest was a D.C. luminary. Then he had a disturbing fall from grace.

“There was a brashness about him that I always associated with the Wall Street ethos,” the Rev. John Paul Wauck, an Opus Dei priest who knew McCloskey, wrote in an email. “You could say that, as a priest, he maintained an entrepreneurial attitude. For some, this was off-putting; for others, it was, I’d say, invigorating and even entertaining.”

McCloskey harnessed that entrepreneurial spirit to persuade people, mostly men, to become Catholics. In New York in 1997, he converted Kudlow, who was recovering from addiction. Mark Belnick, a former general counsel of Tyco International, who described McCloskey as a “great friend” in a New York magazine article, soon followed. They would be among the first in a long line of high-profile conversions that McCloskey facilitated.

“It’s just like the brokerage business or any business of sales,” McCloskey told the National Catholic Reporter in 2003. “You get a reputation, you deal with one person and they mention you to another person . . . and all of a sudden you have a string of people.”

The conversions came naturally to McCloskey because “he just had an absolute certainty about what he was proposing, and he had no hesi­ta­tion at all about unapologetically offering Catholicism as an option,” said Shaw, his co-author.

.. Although he left Washington at perhaps the height of his fame, McCloskey’s legacy is the ongoing influence of the Catholic Information Center. The center’s board includes Leonard Leo, executive vice president of the Federalist Society, which helped shepherd the Supreme Court nominations of Brett M. Kavanaugh and Neil M. Gorsuch. White House counsel Pat Cipollone is a former board member, as is William P. Barr, who served as attorney general under President George H.W. Bush and is now President Trump’s nominee for the same position.

.. The small center — its members and its leaders — continue to have an outsize impact on policy and politics. It is the conservative spiritual and intellectual center that McCloskey had imagined and its influence is felt in all of Washington’s corridors of power.
