Journalists who have studied the history of Catholic disputes about politicians and Holy Communion are probably familiar with this name — Archbishop Joseph Francis Rummel of New Orleans.

There’s a good reason that that.

In 1962, Rummel infuriated segregationists by ordering the integration of all local parish schools. This was especially important in the intensely Catholic culture of Louisiana and it led to debates about how bishops relate to Catholic politicians that continue to this day. That was the topic that loomed in the background during this week’s “Crossroads” podcast (click here to tune that in) focusing on this recent GetReligion post: “Washington Post explores Joe Biden's faith, while embracing language of Catholic left.”

Back to Rummel. The 1964 New York Times obituary for this archbishop noted that he had, as early as 1949, taken actions expressing his opposition — clearly rooted in Catholic teachings — to segregation and other expressions of racism. In 1953 he issued an order stating that Black Catholics no longer had to wait at the end of the line to receive Holy Communion.

But it was the battle over integrating Catholic schools that put this archbishop’s name in the history books. The Times obit noted:

Archbishop Rummel's stand was publicly opposed by three prominent church members: Leander H. Perez Sr., president of the Plaquemines Parish Council, Jackson G. Ricau, executive director of the South Louisiana Citizens Councils, and Mrs. B. J. Gaillot Jr., head of Save Our Nation. Inc.

The three were excommunicated by the Archbishop after they failed to accept letters of “paternal admonition.”

Yes, they were excommunicated. That’s a big step beyond informing them that they should not receive Holy Communion. But note: These Louisiana politicians rejected a direct order from their bishop.

In recent decades, Catholic leaders have argued about whether Rummel’s action is relevant during discussions of how to handle Catholic politicians — especially those seeking national office — who openly support abortion on demand and take other actions to oppose church teachings on marriage and sex.

The question, of course, is where to draw the line when discipling Catholics in public life. American bishops have ended up in a tense standoff linked to controversial actions taken by a rather controversial Catholic — Theodore McCarrick. Yes, that is “Uncle Ted.” As I noted in a recent “On Religion” column:
