Pink granite is used for the entrance platforms. This stone is primarily composed of iridescent bluish-gray crystals of feldspar. The narthex walls are light beige-colored Roman travertine, quarried in Italy. The floor of the narthex is terrazzo, with borders of mottled red limestone, possibly Tennessee marble. Most of the terrazzo panels are very light-colored, consisting of chips of Georgia marble embedded in a light beige cement.
Most chips are white, but some are pink or gray.
Golden-colored terrazzo panels are used for borders. The red limestone used for wall borders contains fossil sea-lily stem fragments and bryozoans. The statue of the Christ Child in the room for adults with children, just off the narthex, is sculpted from unpolished Giallo Siena marble. The flooring of the nave and aisles is like that of the narthex. Shrines of the Jesuit martyrs and the Sacred Heart are made from Giallo Siena marble.
