The interior building has a rich and detailed history with many of the artistic renderings representing numerous Christian and educational themes. The olive vine theme on the floor and walls is a symbol of fertility. The double crosses in the ceiling have a blue back ground in which are set gilded sunbursts and stars, while in the centers are found the Greek letters, XP, which began the word Christos, and the Alpha and Omega. The colours also are symbolic; white is for purity, innocence and faith. Black and white together, purity of life and humiliation. Red is for fire, heat and the creative power. Red and black together, purgatory and the realm of Satan. Green is for hope, of victory and immortality. Grey is for mourning and innocence accused. Blue for the firmament, truth and constancy. Gold is the sun and goodness of God. The anchor represents hope and patience. The lamp is piety and wisdom. The lamb and pennant, represents the Redeemer. The cross is for redemption. The interwoven triangles, represents the Trinity. The Lion is for the Tribe of Judah. The open book with a hand pointing to the Beatitudes, is a symbol of the Gospels. The sword and palm is for martyrdom and victory. The chalice is for faith. The flaming heart is of fervent piety and love. The standard, the wreath and the crown represent victory over evil. The sun, stars and crescent moon, are the luminous nebula which emanates from and surrounds the Divine Essence. The burning bush is for the fervor of the martyrs. I.H.S. originally were the first three letters of the name of Jesus in Greek, but which in Renaissance time were said to stand for Jesus Hominum Salvator, "Jesus, Saviour of men."
