The Apse Mosaic at St. Paul Outside the Walls: Detail of Christ and Four Saints

Basilica of St. Paul Outside the Walls, Rome

Christ sits on his throne and welcomes the faithful to Heaven with the words of Matthew 25:34, VENITE BENEDICTI PATRIS MEI PERCIPITE REGNUM [followed by abbreviations as space is wanting]: "Come ye blessed of my Father, see the kingdom prepared for you from the foundation of the world."

Left of throne the mosaic labels St. Luke on the left and St. Paul on the right. Paul's scroll has his words from Philippians 2:10, IN NOMINE IESU OMNE GENUFLECTATUR CAELESTIUM TERESTRIUM ET INFERNORUM, "At the name of Jesus every knee should bend in Heaven, on earth, and under the earth." Luke's scroll is heavy on abbreviations and I cannot identify it.

Right of the throne are St. Peter on the left and St. Andrew on the right. Peter's scroll reads, TU ES CHRISTUS FILIUS DEI VIVI, "You are the Christ, the son of the living God" (Matthew 16:16). Andrew's scroll reads BEATUS ANDREAS DUM PENDERET IN CRUCE DEPRECATUR DOMINO IESU CRIST[I], "Blessed Andrew while he hung on the cross prayed to the Lord Jesus Christ." This is a variant of a hymn from the Office of St. Andrew, "As blessed Andrew hung on the cross he did not cease to preach the word of God day and night…"
