Why these numbers

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

Contend 60

These were never meant to win an argument. They were meant to get a frightened adult through Lent and into the water, and they are gentle on purpose.

Defend 70

A steady Greek tradition, and we can check it against the mystagogical lectures that follow it. Little to dispute.

Popularity 58

The earliest full course of Christian instruction anybody has, so every account of how the church taught new believers begins here. It speaks early as often as not.

Cited for this book

Cyril taught the creed to catechumens clause by clause through Lent, and made them give it back from memory, because none of them was permitted to write it down. What survives is a shorthand record somebody took anyway — the earliest full course of Christian instruction we have, complete with the bishop telling the congregation to stop letting the candidates hear the next part early.

Moves learned

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

Read it: Engraved on the Memory

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

“This summary I wish you both to commit to memory when I recite it… not writing it out on paper, but engraving it by the memory upon your heart, taking care while you rehearse it that no Catechumen chance to overhear the things which have been delivered to you.”

Cyril of Jerusalem, Catechetical Lecture 5.12 (trans. Gifford, NPNF² 7, public domain). The ellipsis is “and to rehearse it with all diligence among yourselves.”

“…it extends over all the world, from one end of the earth to the other…”

Cyril of Jerusalem, Catechetical Lecture 18.23, the first of four reasons he gives for calling the Church catholic (trans. Gifford, NPNF² 7, public domain).

“For this body shall be raised not remaining weak as now; but raised the very same body, though by putting on incorruption it shall be fashioned anew…”

Cyril of Jerusalem, Catechetical Lecture 18.18 (trans. Gifford, NPNF² 7, public domain).

“We did not really die, we were not really buried, we were not really crucified and raised again; but our imitation was in a figure, and our salvation in reality.”

Cyril of Jerusalem, Mystagogic Catechesis 2.5 (trans. Gifford, NPNF² 7, public domain).
Notes

Jerusalem, most likely around 350, delivered to adults preparing for baptism at Easter. These are not a treatise. They are a class, and you can hear him managing the room.

The creed was never handed to them on paper. They learned it by ear, said it back, and were told to make sure no unbaptised catechumen was in earshot while they practised.

Which is why “catholic” gets four separate meanings in one paragraph of Lecture 18. He is not defining a term for scholars; he is teaching a word his hearers are about to say out loud in public.

The last five lectures were given in Easter week, after the baptism, and explain what had just happened to them. Nobody explains a rite to people who have not been through it yet.
