Gregory of Nazianzus (A.D. 329–389) preached a sermon in the Church of the Resurrection in Constantinople 16 centuries ago on December 25, A.D. 380. This was typical of the sermons the Spirit of God employed to conquer the ancient world for Christ. Today our congregations would rebel: it is too difficult to follow—too intellectual. But that is a harsher condemnation for us and our day than it is of Gregory’s sermon. It was also biblical and it challenged the minds of men and women of the ancient world. Here was no pablum for baby Christians. Here was strong meat for spiritually hungry people who were willing to work intellectually for the solid nourishment of their souls.—Eds.
Christ is born, glorify ye Him. Christ from heaven, go ye out to meet Him. Christ on earth; be ye exalted. Christ in the flesh, rejoice with trembling and with joy; with trembling because of your sins, with joy because of your hope. Christ of a Virgin, without Mother, becomes without Father (without Mother of His former state, without Father of His second). He Who is not carnal is Incarnate; the Son of God becomes the Son of Man.
The Festival is the Theophany or Birthday, for it is called both, two titles being given to the one thing. For God was manifested to many by birth. On the one hand Being, and eternally Being, of the Eternal Being, above cause and word, for there was no word before The Word; and on the other hand for our sakes also Becoming, that He Who gives us our being might also give us our Well-being, or rather might restore us by His Incarnation, when we had by wickedness fallen from well-being. The name Theophany is given to it in reference to the Manifestation, and that of Birthday in respect of His Birth.
Therefore let us keep the Feast, not after the manner of a heathen festival, but after a godly sort; not after the way of the world, but in a fashion above the world; not as our own, but as belonging to Him Who is ours, or rather as our Master’s; not as of weakness, but as of healing; not as of creation, but of recreation.
Now then I pray you accept His Conception, and leap before Him; if not like John from the womb, yet like David, because of the resting of the Ark. Revere the enrolment on account of which thou wast written in heaven, and adore the Birth by which thou wast loosed from the chains of thy birth, and honour little Bethlehem, which hath led thee back to Paradise; and worship the manger through which thou, being without sense, wast fed by the Word. Know as Isaiah bids thee, thine Owner, like the ox, and like the ass thy Master’s crib; if thou be one of those who are pure and lawful food, and who chew the cud of the Word and are fit for sacrifice. Or if thou art one of those who are as yet unclean and uneatable and unfit for sacrifice, and of the Gentile portion, run with the Star, and bear thy gifts with the Magi, gold and frankincense and myrrh, as to a King, and to God, and to One Who is dead for thee. 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 … because they love men, and they love God.…
Look at and be looked at by the Great God, Who in Trinity is worshiped and glorified, and Whom we declare to be now set forth as clearly before you as the chains of our flesh allow, in Jesus Christ our Lord, to Whom be the glory for ever. Amen.
