Why these numbers

The game's own explanation, as a reader sees it in the backpack.

Contend 80

High. It defines its terms first, nature and then person, and once they are fixed, both heresies turn out to come from the same confusion.

Defend 72

Written a few years after Chalcedon, defending exactly the settlement Chalcedon reached, in Latin the West could use. It has had fifteen centuries to be checked and it holds.

Popularity 60

The Latin definition of "person" that every later Christology quotes starts here. It speaks early.

Cited for this book

Boethius heard a bishop’s letter about Christ’s two natures read aloud, and saw that nobody in the room could explain its key phrases. So he went home and wrote this. He defined a person as an individual substance of a rational nature, and showed that Nestorius and Eutyches went wrong in opposite directions from the same mistake.

The quotes behind its moves

How to read these. In Scholar’s Dream, books argue with each other. Each thing a book can do in a debate is a move, and most moves carry a real quotation — the words the book puts on the table when it uses that move.

Strong against lists the opposing books and arguments a move was written to answer. Used against one of them, it hits much harder than usual: ×2 means twice the normal force, ×4 four times. It is the game’s way of saying: this is the sentence that answers that argument. Open an entry to read why.

“Thus Nestorius, rightly holding Christ’s Nature to be double, sacrilegiously professes the Persons to be two; whereas Eutyches, rightly believing the Person to be single, impiously believes that the Nature also is single.”
Boethius, Contra Eutychen et Nestorium 5 (trans. Stewart & Rand, Loeb 1918, public domain).public domain

Opposite Errors, One Mistake

ChristologyArgument · power 88 · 100% accurate

In the gameNestorius and Eutyches fell off the same road on opposite sides — one made two Persons to keep the two natures, the other collapsed the natures to keep the one Person. Both thought a nature and a person had to be counted together. Neither does.

“For in him we live, and move, and have our being. As some of your own poets have said.”
Acts 17:28 (WEB) — Paul at the Areopagus, quoting the Athenians’ own poets back to them.

Status

In the gamePick the part of the opponent’s case that is true and affirm it. That point can no longer be used against you, and the opponent’s Defend falls sharply. It deals no damage. Affirm something false and you have only agreed with an error.

“we have found the definition of Person, viz.: ‘The individual substance of a rational nature.’”

An Individual Substance

ChristologyArgument · power 85 · 100% accurate

In the gameThe sentence every later argument about Christ — and, centuries on, every argument about what a person even is — was built from. Boethius pins it: a person is one particular thing, and a rational one.

×2.5Summa Theologiaea book · why?

Aquinas takes Boethius’s definition of a person and defends it (Summa I, q.29, a.1).

“among followers of the true Faith He is equally believed to be of two natures and in two natures.”

Of and In Two Natures

ChristologyArgument · power 82 · 100% accurate

In the gameThe Eutychians would say Christ was formed FROM two natures and leave it there — one nature after. The catholic keeps both prepositions: of two natures, and still in two natures, after the union as before it.
