He was the first pope to aspire to secular power, the man for whom Gregorian Chant is named, and one of the main organizers of Roman liturgy and its music. He was also one of the prime promoters of monasticism.

September 3, 1894: American neo-orthodox theologian H. Richard Niebuhr, professor at Yale University and author of Christ and Culture (1951), is born.
