Remember when Presbyterians used to confess this about the civil magistrate?

The civil magistrate may not assume to himself the administration of the Word and sacraments; or the power of the keys of the kingdom of heaven: yet he hath authority, and it is his duty, to take order, that unity and peace be preserved in the Church, that the truth of God be kept pure and entire; that all blasphemies and heresies be suppressed; all corruptions and abuses in worship and discipline prevented or reformed; and all the ordinances of God duly settled, administered, and observed. For the better effecting whereof, he hath power to call synods, to be present at them, and to provide that whatsoever is transacted in them be according to the mind of God. (Confession of Faith 23.3)

Of course, imagining Donald Trump presiding over the General Assembly of the PCA might prompt chuckles (moderating debate with Roberts’ Rules, winding up the woke commissioners, Trump supporters’ embarrassment). But even giving “good” presidents this kind of power is precisely why American Presbyterians revised the Confession (at least one reason). The Congregationalist, Barack Obama moderating a General Assembly? The United Methodist, George W. Bush? The Roman Catholic, John F. Kennedy? I don’t think so!

But even in a secular United States, Americans have trouble abandoning the idea of a president’s moral authority. Even those who believe in total depravity struggle with expecting too much of POTUS. Here’s one fairly recent foray into the topic of presidents’ morality at National Public Radio. Surprise, it started with St. Abe:

While Americans often take the idea of the president as a moral leader for granted, Barbara Perry, a presidential historian in Charlottesville at the University of Virginia’s Miller Center, says she has traced this concept back to Abraham Lincoln’s Gettysburg Address in 1863.

The North and South were divided in the middle of the Civil War, and Lincoln sought to bring the country together by pointing to our common heritage, Perry says.

“He points to the fact that our common heritage is that our forefathers came upon this continent and created a new nation, dedicated to the proposition that all men are created equal,” Perry tells NPR’s Audie Cornish. “To me it is the ultimate presidential speech of unification, grief, calming — but also uplifting and inspirational.”

What exactly is moral about social unity, grief over soldiers’ deaths, calm reassurance, uplift, and inspiration? That’s a pretty low bar (not low enough for Trump).

“The president is not always successful in the persuasion, in terms of policy outcomes,” Perry says, “but if he can be successful in at least calming and soothing the nation and showing us a way forward — that someday perhaps we will reach the policy point, as we did with President Kennedy and the ’64 Civil Rights Act — he will have been successful.”

So what, ultimately, is the responsibility of a president in critical moments? Perry says the president primarily serves to comfort the American people in times of crisis. We look to the president as a father figure.

“The president is the very first symbol of American government that children comprehend,” she says. “The president, especially in the modern era, comes into our homes — first by radio, then television, now through all sorts of electronic gadgetry — and so we think of him as part of our life. And that’s why it’s so important for him to model the proper behavior for us.”

The only way this makes sense for Christians is to have two standards, one for Christians, another for citizens. The United States relies on conduct that is outwardly moral in some sense. But that is a far cry from the Confession:

Works done by unregenerate men, although for the matter of them they may be things which God commands, and of good use both to themselves and others; yet because they proceed not from a heart purified by faith, nor are done in a right manner, according to the Word, nor to a right end, the glory of God; they are therefore sinful, and cannot please God, or make a man meet to receive grace from God. (Confession of Faith, 13.7)

A president’s moral authority, accordingly, should proceed from true faith, obedience to God’s word, and an aim to give God the glory.

And yet, we have many Americans who expect presidents to be moral at a time when Christians have been “engaged” in politics in a direct way for at least a generation. You might think that a Christian perspective would reduce expectations for a presidential morality. It is exactly the reverse. Many American who have made a living by flouting conventional standards (think Hollywood celebrities) now have no trouble echoing Jerry Falwell, Sr.

If only Mencken were alive to see this show.
