The Liturgical Prayers of St. Gregory the Great
Henry Ashworth
The authenticity of the service book known to scholars as Gregorian Sacramentary or simply Gregorianum has long been a matter discussion. From mid-eighth century end ninth we find strong external tradition assigning its authorship St. Gregory Great. Doubts on this point were first expressed by George Baron d'Eckhart in 1729, and controversy flared up once more 1890, when traditional view was vigorously defended Dom G. Morin.
