their symbols: Matthew the angel representing the Gospel of the Church; Mark, the lion and inspiration for Peter's teachings or catechesis; Luke, the ox, for his recounting of Christ's infancy; John, the eagle, for the writer of the Spiritual Gospel, recounting the story of "the Word made flesh." Ambo of the Epistle Writers Also by de Courten is the Ambo of the Evangelists, a bronze casting depicting the authors of the apostolic letters to the early Church communities: Peter, with keys to the Kingdom of God; Paul, who died by the sword; James, representing faith sustained by good works; and Jude, carrying a whip representing correction. This particular ambo is used by lectors and cantors during Sunday Masses and other special Church feasts and memorials. Cathedral altar Six tons of monolithic red-black Rosso Imperiale di Solberga granite forms the mensa or table top of the altar. The pedestal is encircled by a bronze bas-relief depicting Old Testament scenes of sacrificial offerings and preparation: Abel's offering of the first sacrifice, the priest Melchizedek giving bread and wine, Abraham's willingness to sacrifice his son Isaac, and the Prophet Elijah receiving bread and water from the Angel of the Lord for strength to continue on his journey. The consecrated altar contains relics, or actual artifacts from the bodies of Saint John the Apostle and Saint Timothy. Cathedra of the See of Chicago A cathedra, or bishop's throne, is what makes the church a cathedral. It is from this chair that Sedes Chicagiensis, or See of Chicago, is presided over by the archbishop of Chicago. Unlike most Roman Catholic cathedra, the Cathedra of the See of Chicago is plain and simple. Its back contains three panels depicting the first Christian teachers: Christ in the center panel, Saint Peter to his right, and Saint Paul to his left. Sanctuary Panels of the Holy Name Above the cathedra are the Sanctuary Panels of the Holy Name, five bronze panels by Attilio Selva representing the Holy Name of Jesus from which the church gets its name. The first panel is of Simeon contemplating the Infant Savior whom Mary presents in the Temple.

The fourth panel is of the Presentation of Jesus in the Temple showing Mary and
