Why these numbers

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

Stamina 76

The Proof of the Gospel was twenty books long. Ten survive, plus a scrap of the fifteenth — so you are holding roughly half of a very large work. Big, but with half of it missing: middling Stamina.

Contend 82

Eusebius does not make one argument, he stacks them — the faith of the patriarchs, the prophets fulfilled, Christ’s moral teaching, the miracles, and the apostles who had nothing to gain by lying. A case built of many cases contends hard.

Popularity 64

Everyone has heard of Eusebius’ Ecclesiastical History. Almost nobody has read this one. Low Popularity — the Proof usually speaks late.

Cited for this book

Written c. A.D. 314–318 as the second half of a single vast project (the Preparation for the Gospel came first). Twenty books originally; books 1–10 and a fragment of book 15 survive. Its author attended the Council of Nicaea in 325.

Development

A book develops as it is read — the fragment becomes the work, the work becomes the corpus.

Moves learned

By levelling up. A book that develops keeps what it knew and learns the rest on its new schedule.

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.

“The questions I would ask them are these: whether any other deceiver… is ever reported to have become as a teacher the cause of meekness, sweet reasonableness, purity, and every virtue in those that he deceived?”

Eusebius, The Proof of the Gospel 3.3 (trans. W. J. Ferrar, 1920, public domain).public domain

“He commanded them besides all this to hold so fast to truth, that so far from swearing falsely they should not need to swear at all.”

The Loftier Morality

EthicsArgument · power 50 · 100% accurate

In the gameEusebius sets Christ’s moral teaching beside every other teacher’s and lets the comparison stand. An argument that has to concede the point sometimes has nothing at all to say next — the foe may be left FROZEN.

“He who pleads his cause first seems right; until another comes and questions him.”

Proverbs 18:17 (WEB).

Question the Premise

RationalityType shift

In the gameChallenge the foundation of an argument before it can be pressed. Lowers the foe’s Contend.

“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.

Affirm

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.

“Christianity is neither a form of Hellenism, nor of Judaism, but… a religion with its own characteristic stamp, and… not anything novel or original, but something of the greatest antiquity, something natural and familiar to the godly men before the times of Moses.”

The Elder Faith

HistoryArgument · power 60 · 100% accurate

In the gameThe charge is that the faith is new, and therefore false. Eusebius answers by going further back than his accusers can: this is the religion of the patriarchs, older than Moses, older than the law, older than the nations bringing the charge.

Strong against
×2Ancestral Customan argument · why?

Eusebius turns the charge around. The faith is not new. It is the faith of Abraham and the patriarchs, older than Rome and older than Moses.

“Such were the far-famed wonders of His power. Such were the proofs of His divinity.”

The Miracles of Jesus

HistoryArgument · power 65 · 95% accurate

In the gameThis is about what Christ did, not only what he taught: his works were done in public, before witnesses. Several books make this argument in their own words.

“Now if any Greek is the accuser, let him realize that his accusations would not please his own teachers, who, it may be, assisted by us, for they have come after us in time, have expressed such sentiments as these in their writings.”

Eusebius, The Proof of the Gospel 3.3 (trans. W. J. Ferrar, 1920, public domain).public domain

“To the supreme God, as a certain wise man has said, we must neither offer by fire, nor dedicate any of the things known by sense… By pure silence and pure thoughts of Him we will worship Him.”

Porphyry, On Vegetarianism 2.34 — named as such and quoted by Eusebius, The Proof of the Gospel 3.3 (trans. W. J. Ferrar, 1920, public domain). The same Porphyry wrote fifteen books against the Christians.public domain

“If then these are the conclusions of eminent Greek philosophers and theologians, how could he be a deceiver who delivers to his pupils not words only but acts, which are far more important than words, to perform, by which they may serve God according to right reason?”

Called as Witness

RationalityArgument · power 62 · 100% accurate

In the gameCall a witness the room already respects, even one who is no friend of yours. Testimony from someone the accuser trusts cannot be dismissed as special pleading. Sometimes lowers the foe’s Contend.

Strong against
×2The True Wordan argument · why?

Call a witness the room already respects, even one who is no friend of the church. Testimony from an opponent is hard to wave away.

The Proof of the Gospel spends eight of its ten surviving books doing one thing: setting a Hebrew prophecy beside the event, and then doing it again. No single sentence carries the case, which is rather the point of it.

See Eusebius, The Proof of the Gospel, books 1–10 (trans. W. J. Ferrar, 1920). Described, not quoted — the sentence above is the game’s own.

Prophecy Fulfilled

Biblical TheologyArgument · power 85 · 90% accurate

In the gameProphecy after prophecy set beside the gospels: the town, the mother, the years, the death, the scattering. The number of fulfilments is the argument.

Strong against
×2"Your God Let Rome Fall"an argument · why?

Eusebius set each prophecy beside its fulfilment. The God who foretold Christ’s coming rules all of history, including the rise and fall of Rome.

“We will extend our lies not only to men of our own race, but go forth to all men, and fill the whole world with our fabrications about him.”

Eusebius, The Proof of the Gospel 3.5 (trans. W. J. Ferrar, 1920, public domain) — the apostles’ imaginary conspiracy meeting, written to be laughed at.public domain

“For what could be finer than to make both gods and men our enemies for no reason at all, and to have no enjoyment of any kind, to have no profit of our dear ones, to make no money, to have no hope of anything good at all, but just to be deceived and to deceive without aim or object?”

Sarcasm

RationalityArgument · power 60 · 95% accurate

In the gameSay the argument back to it, straight-faced and in full, until the shape of it does the refuting. Often finds the telling stroke — and occasionally goes too far and misses.

Read it: Something of the Greatest Antiquity

The passages the Scriptorium holds on screen, word for word from a public-domain translation. Written in Koine Greek.

“Christianity is neither a form of Hellenism, nor of Judaism, but… a religion with its own characteristic stamp, and… not anything novel or original, but something of the greatest antiquity, something natural and familiar to the godly men before the times of Moses.”

Eusebius, The Proof of the Gospel 1.2 (trans. Ferrar, 1920, public domain).

“We will extend our lies not only to men of our own race, but go forth to all men, and fill the whole world with our fabrications about him.”

“He commanded them besides all this to hold so fast to truth, that so far from swearing falsely they should not need to swear at all.”

Notes

Twenty books once; ten survive. The companion volume to the Preparation for the Gospel, and the larger apologetic project of the man better known for the Ecclesiastical History.

The thesis in the first passage is the one that answers the standard pagan charge. New religions are false religions — so Eusebius argues that this one is older than Moses, and that Abraham was already living it.

The middle two passages are him doing something a defender rarely risks. He writes the conspiracy speech for the other side, in the apostles’ mouths, as well as he can — and then lets the reader hear how it sounds.

It is the oldest move in apologetics and still the hardest: state the accusation better than the accuser did, out loud, before answering it.
