Edwards repeatedly uses the word condescension, and we need to understand that this is a theological word and concept, with no hint of the negative connotations that the word holds in common usage today. Christ’s condescension was his descent from a higher divine state to a lower human one, accompanied by his relinquishing of divine privilege in order to accomplish an action (the salvation of people) that strict justice does not require.
In this act of taking on human nature, Christ’s infinite condescension [“descending to be with”] wonderfully appeared, that he who was God should become man, that the word should be made flesh, and should take on him a nature infinitely below his original nature. And it appears yet more remarkably in the low circumstances of his incarnation: he was conceived in the womb of a poor young woman, whose poverty appeared in this, when she came to offer sacrifices of her purification, she brought what was allowed of in the law only in case of a person . . . [who] was so poor that she was not able to offer a lamb.
And though his infinite condescension thus appeared in the manner of his incarnation, yet his divine dignity also appeared in it; for though he was conceived in the womb of a poor virgin, yet he was conceived there by the power of the Holy Ghost. And his divine dignity also appeared in the holiness of his conception and birth. Though he was conceived in the womb of one of the corrupt race of mankind, yet he was conceived and born without sin. . . .
His infinite condescension marvelously appeared in the manner of his birth. He was brought forth in a stable because there was no room for them in the inn. The inn was taken up by others who were looked upon as persons of greater account. The Blessed Virgin, being poor and despised, was turned or shut out. Though she was in such extreme circumstances, yet those that counted themselves her betters would not give place to her; and therefore, in the time of her travail, she was forced to betake herself to a stable; and when the child was born, it was wrapped in swaddling clothes, and laid in a manger. There Christ lay a little infant, and there he eminently appeared as a lamb.
But yet this feeble infant, born thus in a stable, and laid in a manger, was born to conquer and triumph over Satan, that roaring lion. He came to subdue the mighty powers of darkness, and make a show of them openly, and so to restore peace on earth, and to manifest God’s good-will towards men, and to bring glory to God in the highest, according as the end of his birth was declared by the joyful songs of the glorious hosts of angels appearing to the shepherds at the same time that the infant lay in the manger; whereby his divine dignity was manifested. . . .
