If we step back from the faux-rage at supposed anti-Catholicism against SCOTUS nominee Amy Coney Barrett the big story here remains the fact that there are SIX Catholic on the High Court.

The real question: Why ZERO Evangelicals?

This analysis by @RonBrownstein is the best I've seen so far on the dynamics behind this Roman dominance (Jack Chick RIP):

"How conservative Catholics became supreme on GOP's court" https://www.cnn.com/2020/09/27/politics/conservative-catholics-gop-supreme-court/index.html

Brownstein neatly and rightly says this "reflects an ideological convergence and an institutional divergence." There is the "ecumenism of the trenches" among culture war Catholics and Evangelicals, but RC's have the institutional advantage in law schools and universities...

I do wonder if there are some further cultural and theological differences that help explain why we have so many Catholic justices and no Evangelicals.

One might be that the approach to faith mirrors the approach to the law...

I have always been struck by the fact that Liberty University, which wants to be the Evangelical Notre Dame, prides itself on having the only law school with a replica of the actual Supreme Court chambers:

I have been told that this ...

...This is so that Liberty U law students can get used to arguing BEFORE the bench of the High Court. That's telling. They want to argue to the justices, not necessarily to BE a justice.

That is reflective perhaps of a kind of missionary and evangelical orientation...

This evangelical legal apologetics differs from the more process and of course legal orientation of Catholicism. We have, after all, and entire Code of Canon Law! And canon lawyers! And courts! And judges! It's all built in to Catholic culture and theology ...

Catholics also have a philosophical and theological and university tradition that Evangelicals do not. If you study Aquinas you are probably better prepared to argue for, or against, Originalism, for example (we have the EXACT SAME debates in Catholicism)...

This is not to re-up Mark Noll's "Scandal of the Evangelical Mind" argument (it may be a factor--Joshua Wilson makes the supply/demand point in the CNN piece). It's more about the Evangelical tradition of social activism for change rather than legal and procedural processes...

...Catholic, like Jews (also overrepresented on the High Court) have these intellectual and cultural traditions. But they also had the experience of being minorities within a Protestant society. They knew they needed legal protections and needed to win them for themselves...

...Evangelicals perhaps took Protestant dominance for granted, and as they lost that grip they channeled their fear into political and social activism and "outsourced their judicial appointments to conservative Catholics," as Randall Balmer says.

Perhaps the next step for Evangelicals will be to have one of their own named to the Supreme Court. It may be too late, even if they had a candidate. We are talking as always about White Evangelicals. The next Evangelical on the High Court is more likely to be a Black Democrat.

White Evangelicals are the backbone of the GOP. That they have none of their own on the High Court even as their numbers and influence look to wane is remarkable. FIN.
