_Of the incarnation of the eternal and only begotten Son of God._ We confess: That the exalted and true God faithfully kept and fulfilled his exceeding great and precious promises, which he had made in the beginning concerning his Son, who had been foreordained to this end before the foundation of the world, but in these last times was manifest for our sakes.
This glorious and cheering promise was originally given to fallen Adam and Eve, and was afterwards renewed in their seed, as in Abraham, Isaac, and Jacob, Moses and David. Of him did all the prophets prophesy, and on him did all the pious fathers hope with a firm confidence (as though they had seen him), that Shiloh would come from Judah, and that this beautiful star would arise out of Jacob. This truly and really took place as follows: When everything was in tranquillity, when the royal sceptre had departed from Judah, and the seed of Jacob was under tribute to the heathen; then the gracious God remembered his holy covenant, and sent his true, real Word or Son out of heaven, from his royal throne; having to this end foreordained and elected the righteous Joseph, of the house and generation of David, whose espoused wife was Mary, whom God had blessed and chosen for this purpose above all other women.
To this Joseph and Mary the Holy Ghost points from generation to generation, as well as to the town of Bethlehem, out of which this Light long before promised was to arise and come forth; in order that all the pious who waited and hoped for this salvation, might have a certain consolation and knowledge from which tribe, city and place they were to expect this Savior of the world.
Thus Mary received the message through the angel of God, and believed it, being overshadowed by the power of the Highest, and conceived of the Holy Ghost the true, real Word, which was in the beginning with God, and by which all things were created. The same, through the effectual power of the Almighty God, became flesh or man in her, and was born of her, the Son of the Most High God, whom she had before conceived of the Holy Ghost.
Thus the eternal and only begotten Son of the living God became a visible man subject to suffering. He was wrapped in swaddling clothes, laid in a manger, and brought up at Nazareth under the care of his [imputed] father and his mother. He hungered, thirsted, was wearied with walking, sighed and wept, and increased in wisdom and stature, and in favor with God and man; so that the eternal, only begotten Son of the living God, in the time of his incarnation, did not continue like his heavenly Father in an invisible, impassive, immortal, and spiritual form, but for our sakes, humbled himself into a visible, passive, mortal, and servile form, became like unto us men in all things, except sin; in order thereby to heal us from the poisonous bite of the serpent, and from everlasting torment.
Hence, all true witnesses of Jesus Christ are bound, by virtue of the holy Scriptures, to believe and confess: That this same Word, which was in the beginning with God, and was God, by which all things were made, proceeded from God his Father, came into the world, and, through the power of God, became himself man or flesh, so that the glory of the only begotten Son of the Father, full of grace and truth was touched and seen.
Thus he who before was like unto his Father in brightness and glory--not given or usurped God-likeness, but one peculiar to him by nature--left his brightness and glory, and humbled himself, and became in form like unto us men; he who before was greater than the angels, and in an invisible, immortal form, like unto God his Father, was now made lower than the angels, and became like unto his brethren in a visible and mortal form. He who could have had joy with his Father, and was surrounded by eternal riches, became poor for our sakes, and suffered on the cross, despising the shame. He who in the presence of the apostles ascended heavenward, was the same who before had descended from God out of heaven into the lower parts of the earth; and the same ascended above all heavens. This is the mystery of godliness, which is great, but on account of their carnal and flickering reason, is believed by but few: that God the Son was thus manifest in the flesh: and that he appeared, as a true Redeemer and Savior, and eternal Light, to them who sat in darkness and in the shadow of death.
