Gregory the Great was pope from 590 to 604. Much of what is known about his papacy comes from the collection of his letters, called the Registrum epistularum, that was assembled after his death. Over 850 of his letters survive, to a vast array of addressees on an equally vast array of subjects. Three are translated here. The first is Letter 1.24, the encyclical letter that Gregory sent in February 591 to the patriarchs of Constantinople, Alexandria, Antioch, and Jerusalem shortly after his elevation to the papacy, as a token of his communion with them. While the bulk of the letter deals with pastoral concerns, its last paragraph (translated below) contains a profession of faith meant to assure his fellow patriarchs of his orthodoxy. Here Gregory confesses his adherence to Nicaea, Constantinople, Ephesus I, Chalcedon, and Constantinople II with its condemnation of the Three Chapters.
