We believe that by this conception the person of the Son is inseparably united and connected with the human nature; so that there are not two Sons of God, nor two persons, but two natures united in one single person; yet each nature retains its own distinct properties. As, then, the divine nature has always remained uncreated, without beginning of days or end of life, filling heaven and earth, so also has the human nature not lost its properties but remained a creature, having beginning of days, being a finite nature, and retaining all the properties of a real body. And though He has by His resurrection given immortality to the same, nevertheless He has not changed the reality of His human nature; forasmuch as our salvation and resurrection also depend on the reality of His body. But these two natures are so closely united in one person that they were not separated even by His death. Therefore that which He, when dying, commended into the hands of His Father, was a real human spirit, departing from His body. But in the meantime the divine nature always remained united with the human, even when He lay in the grave; and the Godhead did not cease to be in Him, any more than it did when He was an infant, though it did not so clearly manifest itself for a while. Wherefore we confess that He is very God and very man: very God by His power to conquer death; and very man that He might die for us according to the infirmity of His flesh.
We believe that God, who is perfectly merciful and just, sent His Son to assume that nature in which the disobedience was committed, to make satisfaction in the same, and to bear the punishment of sin by His most bitter passion and death. God therefore manifested His justice against His Son when He laid our iniquities upon Him, and poured forth His mercy and goodness on us, who were guilty and worthy of damnation, out of mere and perfect love, giving His Son unto death for us, and raising Him for our justification, that through Him we might obtain immortality and life eternal.
We believe that Jesus Christ is ordained with an oath to be an everlasting High Priest, after the order of Melchizedek; and that He has presented Himself in our behalf before the Father, to appease His wrath by His full satisfaction, by offering Himself on the tree of the cross, and pouring out His precious blood to purge away our sins, as the prophets had foretold. For it is written: He was wounded for our transgressions, he was bruised for our iniquities; the chastisement of our peace was upon him; and with his stripes we are healed. He was led as a lamb to the slaughter, and numbered with the transgressors; and condemned by Pontius Pilate as a malefactor, though he had first declared Him innocent. Therefore, He restored that which he took not away, and suffered, the righteous for the unrighteous, as well in His body as in His soul, feeling the terrible punishment which our sins had merited; insomuch that his sweat became as it were great drops of blood falling down upon the ground. He called out: My God, my God, why hast thou forsaken me? and has suffered all this for the remission of our sins.
Wherefore we justly say with the apostle Paul that we know nothing save Jesus Christ, and him crucified; we count all things but loss and refuse for the excellency of the knowledge of Christ Jesus our Lord, in whose wounds we find all manner of consolation. Neither is it necessary to seek or invent any other means of being reconciled to God than this only sacrifice, once offered, by which he hath perfected forever them that are sanctified. This is also the reason why He was called by the angel of God, JESUS, that is to say, SAVIOR, because He would save his people from their sins.
