The Alpha and Omega, the first and last letters of the Greek alphabet, are used as the emblem of the eternity of our Lord: "I am Alpha and Omega, the beginning and the end, the first and the last."

The Star is a symbol of Christ. It owes its origin to His own words, "I am the root and the offspring of David, and the bright and morning star." It was by the leading of a star that God manifested His only begotten Son to the Gentiles. The five-pointed star commonly represents the star of Bethlehem. It is a Christmas and Epiphany emblem.
