Commissioned as part of a Millennium project in the York chaplain’s own parish, Tom Denny’s inspirational stained glass window, takes as its starting point, a text from Isaiah chapter 43 verses 18-21. Through the medium of this vision of a transfigured world, the window explores the relationship of Time to Eternity and the sacramental nature of creation, and roots both into the particularities of the small rural parish of Bolton Percy. The governing idea of "waters", also relates the window to the nearby font.

Tom Denny has pioneered a new and exciting technique of acid-etching, staining and painting on glass, which creates an astonishing movement of light and colour across the surface of the window.
