The interior is notable for its huge tapestry (once thought to be the world's largest) of Christ, designed by Graham Sutherland, the emotive sculpture of the Mater Dolorosa by John Bridgeman in the East end, and the Baptistry window designed by John Piper (made by Patrick Reyntiens), of abstract design that occupies the full height of the bowed baptistery, which comprises 195 panes, ranging from white to deep colours. The stained glass windows in the Nave, by Lawrence Lee, Keith New and Geoffrey Clarke, face away from the congregation. Spence's concept for these Nave windows was that the opposite pairs would represent a pattern of growth from birth to old age, culminating in heavenly glory nearest the altar — one side representing the Human, the other side, the the Divine.
