If you are one of those who are as yet unclean, ... unfit for sacrifice, and of the gentile portion – then run with the Star, and bear your Gifts with the Magi:  Gold, frankincense, and myrrh, as to a King, to God, and to One who is dead for you.  With Shepherds glorify Him; with Angels join in chorus; with Archangels sing hymns.

Let this Festival be common to the powers in heaven and to the powers upon earth.  For I am persuaded that the Heavenly Hosts join in our exultation and keep high Festival with us today.

-- St. Gregory Nazianzen, Oration 38, Section 17
