The following are excerpts from a Sept. 1 story in the Washington Post. A link to the full story is provided below.

For the typical American Catholic, seeing Cardinal Tim Dolan, the country’s top bishop, give the closing prayer at the GOP convention was the big political event of the summer. But for Catholics who know how the church really operates in Washington, something far more significant went down last week: John Carr retired.

For the past quarter-century, Carr has been the most important policy adviser to the country’s Catholic bishops, their Karl Rove on everything from health care to clergy sex abuse. He describes himself as “a 62-year-old, white, round, church bureaucrat,” but Carr’s career is a road map for how Catholicism and politics have mixed in Washington for a generation.

The former seminarian has been lauded by U2 singer Bono for successfully pressing Third World debt relief on Capitol Hill and has challenged Rep. Paul Ryan (R-Wis.), a Catholic, for not demanding more financial sacrifice from middle-class Americans in order to help the poor. When the head of the church’s key mental-health facility for clergy was dying of AIDS in the late 1980s, Carr negotiated how to make the news public. When the Hill’s top poverty advocates were desperate during last year’s budget talks to save assistance programs for the poor, Carr led the effort.

“I’m just so used to John being our leader,” Rabbi David Saperstein, the Reform Jewish movement’s longtime D.C. representative, said last week after describing what he called Carr’s role in convincing a major senator of the impact of climate change on the world’s poor. Carr, it turned out, wasn’t actually at that meeting. But that’s the way it is with Carr — he’s been so influential for so long that sometimes Hill faith lobbyists just assume his involvement in key events.

When a small group of prominent faith advocates organized a good-bye dinner last week for Carr, they intentionally picked “the Captain’s Room” at Ruth’s Chris Steak House.

The mixing of religion and politics engenders powerful passions, but insiders know that faith advocates typically aren’t players in Washington. Carr is one of the few exceptions. But his influence is only part of the reason Carr’s exit Friday is being mourned. Some are also concerned about who will come after him.

At a time when Catholics are watching their community become increasingly polarized along political lines, Carr is considered a dying breed: a Catholic moderate with a foot firmly in both camps. He worked for the White House Conference on Families under President Jimmy Carter and was a Democratic candidate. He has also zealously slammed the Obama White House for its mandate that employers provide contraception coverage to employees. At a good-bye event this week at the U.S. Conference of Catholic Bishops headquarters, Carr’s voice sounded angriest when he bemoaned the Bush-led Iraq War.

Catholics are becoming more divided over whether they focus on church teachings against war and poverty or the ones against abortion and gay marriage. Catholic progressives are particularly worried about Carr leaving as Church officialdom in recent years has put greater and greater emphasis on defending the unborn.

“If John Carr hadn’t been there for the past 20 years, who knows what would have happened?” said John Gehring, who focuses on Catholic issues for the left-leaning advocacy group Faith in Public Life and often clashes with the bishops…
