"One summer afternoon in the year 1054, as a service was about to begin in the Church of the Holy Wisdom (in Greek, "Hagia Sophia"; often called "Saint Sophia" or "Sancta Sophia" by English writers) at Constantinople, Cardinal Humbert and two other legates of the Pope entered the building and made their way up to the sanctuary. They had not come to pray. They placed a Bull of Excommunication upon the altar and marched out once more. As he passed through the western door, the Cardinal shook the dust from his feet with the words: "Let God look and judge." A deacon ran out after him in great distress and begged him to take back the Bull. Humbert refused; and it was dropped in the street."
