The murals at the front of the Cathedral were designed and painted by Felix Lieftuchter in 1918. They represent a combination of Byzantine, Spanish Gothic, and modern styles. At the center is the figure of Christ on the Cross, with God the Father, and the Holy Spirit above. At the bottom of the Cross are a pelican and her children, symbolizing Christ's sacrifice since the pelican feeds its young with its own blood.
The left mural depicts prominent Christian figures, (St. Joan of Arc, St. Venatius, St. John the Baptist, St. Gregory, St. Vincent de Paul, St. Agnes, St. Pascal Baylon, St. Jerome, St. Helena, St. Stephen), and the right mural depicts Old Testament figures (Adam and Eve, Isaiah, Ester, Ruth, Melchizedek, Moses, David, St. Anne, Judith).
The mural in the west transept is of the woman (traditionally identified as Mary Magdalene) washing the feet of Jesus. In the east transept there is portrayed the appearance of Jesus to Mary Magdalene following the Resurrection.
The crossing over the altar contains panels of angels, as do the upper regions of the vaulting throughout the Cathedral. The coats of arms of the eight bishops of the diocese are also found in the walls of the transepts.
The striking blue and starred ceiling over the Blessed Sacrament chapel signifies the vault of heaven. Also painted by Felix Lieftuchter, it represents the influence of modern art on the artist's work.
