Pope Gregory I writes to Severus, the patriarch of Aquileia, requesting on behalf of the emperor (Maurice) that he come to Rome with his clergy and be judged on a synod (for his unwillingness to condemn the Three Chapters and his perseverance in supporting the schism).
The bishops of the ecclesiastical province of Aquileia write to emperor Maurice, beseeching him not to allow their metropolitan, Archbishop Severus of Aquileia, who was forcefully taken to the pope in Rome, to be put on trial and judged by the adversaries of the Three Chapters, that is, the non-schismatic clergy; the bishops expound their viewpoints on the theological controversy, their fealty to the Ecumenical Council of Chalcedon, and why they refuse to denounce the so-called Three Chapters condemned by Emperor Justinian I and the Ecumenical Council of Constantinople in 553.
Emperor Maurice writes to Pope Gregory I, urging him not to treat violently the schismatic bishops of the ecclesiastical province of Aquileia (the "Istrian bishops") and not to compel them to journey to Rome.
