The harmony of the divine attributes in the contrivance and accomplishment of man's redemption…

Now for the making expiation of Sin, there was a necessary concurrence of the two Natures in our Redeemer. He must be Man; for the Deity was not capable of those Submissions and Sufferings which were requisite to expiate Sin. And he must be Man, that the sinning nature might suffer, and thereby acquire a title to the Satisfaction that is made. The meritorious imputation of Christs Sufferings to Man is grounded on the union between them, which is as well natural in his partaking of Flesh and Blood, as moral in the consent of their Wills. As the Apostle observes, That he who sanctifies, ¹and they that are sanctified are all one; So he that suffers, and they for whom he suffers must have communion in the same nature. For this reason, God having resolved never to dispense Mercy to the fallen Angels, ⟨p. 88⟩the Redeemer did not assume the Angelical nature, but the seed of Abraham.
