 After he retired, Newbigin regularly had theology students come over from King's College London to read chapters of theological texts to him since his eye vision had diminished.Despite his fading eyesight, he continued preaching; he told parishioners at St Paul's Church in nearby Herne Hill that when he preached, he would prepare his entire homily in his head long before he was scheduled to give it, and preach from memory.Sydney Carter was a regular attender of the services when he preached.
