100 theologians before the 20th century

Earlier this summer I set myself the task of creating a list of 100 theologians before the 20th century. Partly for myself, since I'm an inveterate list-maker and lists help me organize my reading habits; in this case, I would see where my training had left gaps and blind spots that I needed to fill in. But partly, also, for my students, who regularly ask me who they should read from the tradition—not only where to start, but a kind of curriculum or "who's who." So I set out to answer that very question: who's who?

The current list has 153 entries on it. I still want to cull it down to a clean 100, but I figured I would share it here in its unfinished, bloated form. I covet your corrections: Who am I missing? Who have I misnamed? Who is or is not a saint? Whose dates are mistaken? If you had to cull the list down to 100, which dozen (or more) figures would you nix?

I've separated the list into four groups, ranging from 32 to 50 theologians per period: patristic, medieval, reformation, and modern. The cut-offs, naturally, are bound to be arbitrary, but they're roughly accurate, I think. I'm a Westerner making a list in the West, so the Protestant Reformation is a meaningful period in a way that it isn't for the East—but then, I conclude that "age" with Dositheus II, who is a fitting representative of the East's encounter with reformed faith.

As for my goals and criteria:

First, the list is ecumenical; Orthodox, Catholic, and Protestants of every stripe are included.

Second, influence is important; I want the "relevant" names who decisively drove events, doctrines, controversies, etc.

Third, substance is important, too; indeed, on the final list I'm willing to opt for quality over legacy, if it comes down to that.

Fourth, I want epochs, traditions, regions, cultures, and languages to be disparate and representative of the church catholic at any one slice of time in history.

Fifth, orthodoxy is preferable but not required. Partly that's the nature of an ecumenical list (plenty of folks here have anathematized one another!), but even in terms of loose small-o orthodoxy, there a few whose credentials are questionable. So be it—if their thought is significant and worth engaging.

Sixth, candidates for the list have to have left substantial theological writings: St. Benedict, St. Lawrence, and St. Francis are all left off for that reason.

Seventh, I've included a few poets, but only those whose theological imaginaries have decisively informed the church's grammar and devotional practices, such as Dante and Milton; doubtless Herbert, Donne, and Hopkins, among others, could also be included, but I've left them off for now.

Eighth, the cut-off for the 20th century is difficult. What if your someone's straddles both sides of the dividing line? One criterion I used was whether a theologian's writing was equally distributed, or weighted toward the 19th century; another was whether a theologian's major work came before the year 1900. In the end, though, since (a) World War I ended in 1918, (b) Barth's Römerbrief came out in 1919, and (c) the current year is 2020, I used the "hard" cap of 1920.

Finally: Why theologians before the 20th century? First, because almost to a person, these are figures my students have never heard of and certainly have never read. Second, because duh, these are the fathers and mothers of the faith, who handed it down for 19 centuries to the present; they are worth attending to for their own sake. But third, because if I were to make a list of theologians worth reading from the last 100 years, I'd come up with at least as many names, and probably more. That's the job most seminaries and classrooms presuppose as the relevant task, apart from the stray history class or two. But that ends up sidelining the thinkers below. Imagine instead a graduate program in theology that ensured that students would read 2-4 major works by each of the theologians below (or at least by 100 of them). Imagine the theological range and depth, indeed the spiritual formation, that students would receive. Some programs are in fact trying that out. May their tribe increase.

In any case: to the list. Again, I welcome feedback. Leave a comment or drop me a line directly (brad DOT east AT acu DOT edu). Enjoy. [Update: suggested additions follow the list.]
