Stories where
you think along.

Discover the Bible, the Church Fathers and the foundations of the faith, one encounter at a time.

The door shuts before the last of them have even taken their seats. Cyril does not wait: what he wants to say tonight will sound like blasphemy to most unless he explains it at once.

Continue
Cyril of Jerusalem

The Creator, who once formed Adam from earth, was not ashamed of it. Ask yourself tonight: why should he be ashamed to form himself from the flesh of a Virgin?

Continue

On the wall of the hall hangs a fresco: the angel bringing Mary the message. Cyril stands before it and waits until every gaze rests there.

Cyril of Jerusalem

How can a virgin conceive a child, entirely without a man? Before you shake your head, ask in return how Eve herself came into the world.

Continue
Cyril of JerusalemCatechetical and Mystagogical Lectures

Scripture says that she came forth from Adam’s rib. If Eve was born from a male rib without a mother, should not a child be able to be born without a man from a virgin womb?

Continue

Cyril falls silent and lets the image simply remain: a cave near Bethlehem, a child in the manger, between ox and donkey.

Cyril of Jerusalem

How much, do you truly think, is your own body worth in God’s eyes?

Continue

A friend tells you that the body is lowly and that only the soul matters before God. What do you answer her in Cyril’s spirit?

The Incarnation honors the body that God himself once formed from earth with his own hands and now assumes for himself.

Work in progress V8: historical original art, shorter fade intervals, restored motion stage and original review texts. Search and UI adaptations are marked. The full native sources, video paywall, topic cards and streak flame are not connected yet. No desktop app and no production deployment.

Historical originals

No redrawing.
No AI icons.

Nine different historical works. Original colors and proportions are preserved; only soft masks and transparency blend the images in. The museum originals are Public Domain / Open Access (CC0), the two Commons reproductions are marked PD-Art. The individual sources are listed right next to the images.

Your app remains
the source.

Existing original files can be loaded locally here. Nothing is uploaded and no file is changed.

Existing audiobook and word study clips, quest world covers and reading plan images are recognized by their file names. The exact topic card composition and the streak flame additionally need the approved native mapping.

Planned original choreographies

Bible: Verses → tap a verse → “Explain” → commentary → Logos and pie chart.

Reading plans: three original plan cards → enlarge selection → original calendar → switch daily reading → original streak flame.

These two complete sequences are only shown as an original app demo once the required files are actually connected.
