On the rear wall of the church is the lyric representation of the Nativity with the Adoration of the Shepherds and the Kings, by George Breck. Above this we find the two holy cities of Bethlehem and Jerusalem on either side of the rose window and above, the sky with sun, moon and stars. At the top, again the words, this time in Latin: “In the beginning God created the heaven and the earth.” Under the rose window we glimpse Adam awakening to life in the Garden of Eden.
On the front of the church facade, around the rose window, we find the four angelic creatures which symbolize the four Evangelists: the angel of St. Matthew, the lion of St. Mark, the ox of St. Luke, and the eagle of St. John (based on the Ezekiel 1:4 and Revelation 4:6). Over the west entrance doors we see a mosaic representing St. Paul in his own hired dwelling in Rome, preaching the gospel to all, but constantly guarded by the soldier seen in the picture.
