Scripture on the screen, without anyone typing.

Lumen is a scripture projection tool built for the sanctuary. It listens to the sermon as it is preached, recognises a biblical reference the moment the preacher names it — “turn with me to Romans chapter eight, verse twenty-eight” — and puts that passage on the screen the congregation is watching, usually within a few seconds. No one has to search a slide deck while the sermon moves on, and no one has to guess whether the verse on screen is the one being read aloud.

Behind the display sits a library of public-domain editions in nine languages, so a church reading from the King James, the World English Bible, Reina-Valera, the Almeida or the Clementine Vulgate can project the text it actually uses, with no licensing to chase. Alongside the canon is a comparative shelf — the early fathers, the Dead Sea Scrolls, the Qur’an, the Bhagavad Gita, the Tao Te Ching, the Dhammapada — offered for study and for the sermon, never presented as scripture. Every reference recognised during a service is kept with its time, and the whole service, with its summary, can be saved and revisited.

Lumen is made for the people who carry the Sunday: preachers who quote from memory, the AV and media volunteers running a screen from a laptop at the back of the room, small congregations without a production team, and study groups who want to follow a passage as it is read. It assumes a microphone, a projector and a browser — nothing more.

Who builds it: Lumen is built by a small independent team of engineers and church audio volunteers, most of whom spend their own Sundays behind a mixing desk. The project began as a fix for a familiar problem — a sermon quoting a passage faster than anyone could find it — and it is still shaped by the people who use it week by week. Questions, corrections and requests from congregations are welcome.
