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, that each nature retains its own distinct properties. As then the divine nature hath always remained uncreated, without beginning of days or end of life, filling heaven and earth: so also hath 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 hath by his resurrection given immortality to the same, nevertheless he hath 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.
Article 18: Of the Incarnation of Jesus Christ.
We confess, therefore, that God did fulfill the promise, which he made to the fathers, by the mouth of his holy prophets, when he sent into the world, at the time appointed by him, his own, only-begotten and eternal Son, who took upon him the form of a servant, and became like unto man, really assuming the true human nature, with all its infirmities, sin excepted, being conceived in the womb of the blessed Virgin Mary, by the power of the Holy Ghost, without the means of man, and did not only assume human nature as to the body, but also a true human soul, that he might be a real man. For since the soul was lost as well as the body, it was necessary that he should take both upon him, to save both. Therefore we confess (in opposition to the heresy of the Anabaptists, who deny that Christ assumed human flesh of his mother) that Christ is become a partaker of the flesh and blood of the children; that he is a fruit of the loins of David after the flesh; made of the seed of David according to the flesh; a fruit of the womb of the Virgin Mary, made of a woman, a branch of David; a shoot of the root of Jesse; sprung from the tribe of Judah; descended from the Jews according to the flesh; of the seed of Abraham, since he took on him the seed of Abraham, and became like unto his brethren in all things, sin excepted, so that in truth he is our Immanuel, that is to say, God with us.
Article 17: Of the Recovery of Fallen Man.
We believe that our most gracious God, in his admirable wisdom and goodness, seeing that man had thus thrown himself into temporal and eternal death, and made himself wholly miserable, was pleased to seek and comfort him, when he trembling fled from his presence, promising him that he would give his Son, who should be made of a woman, to bruise the head of the serpent, and would make him happy.
Article 16: Of Eternal Election.
We believe that all the posterity of Adam being thus fallen into perdition and ruin, by the sin of our first parents, God then did manifest himself such as he is; that is to say, merciful and just: Merciful, since he delivers and preserves from this perdition all, whom he, in his eternal and unchangeable counsel of mere goodness, hath elected in Christ Jesus our Lord, without any respect to their works: Just, in leaving others in the fall and perdition wherein they have involved themselves.
Article 15: Of Original Sin.
We believe that, through the disobedience of Adam, original sin is extended to all mankind; which is a corruption of the whole nature, and an hereditary disease, wherewith infants themselves are infected even in their mother's womb, and which produceth in man all sorts of sin, being in him as a root thereof; and therefore is so vile and abominable in the sight of God, that it is sufficient to condemn all mankind. Nor is it by any means abolished or done away by baptism; since sin always issues forth from this woeful source, as water from a fountain; notwithstanding it is not imputed to the children of God unto condemnation, but by his grace and mercy is forgiven them. Not that they should rest securely in sin, but that a sense of this corruption should make believers often to sigh, desiring to be delivered from this body of death. Wherefore we reject the error of the Pelagians, who assert that sin proceeds only from imitation.
Article 14: Of the Creation and Fall of man, and his Incapacity to perform what is truly good.
We believe that God created man out of the dust of the earth, and made and formed him after his own image and likeness, good, righteous, and holy, capable in all things to will, agreeably to the will of God. But being in honor, he understood it not, neither knew his excellency, but willfully subjected himself to sin, and consequently to death, and the curse, giving ear to the words of the devil. For the commandment of life, which he had received, he transgressed; and by sin separated himself from God, who was his true life, having corrupted his whole nature; whereby he made himself liable to corporal and spiritual death. And being thus become wicked, perverse, and corrupt in all his ways, he hath lost all his excellent gifts, which he had received from God, and only retained a few remains thereof, which, however, are sufficient to leave man without excuse; for all the light which is in us is changed into darkness, as the Scriptures teach us, saying: The light shineth in darkness, and the darkness comprehendeth it not: where St. John calleth men darkness. Therefore we reject all that is taught repugnant to this, concerning the free will of man, since man is but a slave to sin; and has nothing of himself, unless it is given from heaven. For who may presume to boast, that he of himself can do any good, since Christ saith, No man can come to me, except the Father, which hath sent me, draw him? Who will glory in his own will, who understands, that to be carnally minded is enmity against God? Who can speak of his knowledge, since the natural man receiveth not the things of the spirit of God? In short, who dare suggest any thought, since he knows that we are not sufficient of ourselves to think anything as of ourselves, but that our sufficiency is of God? And therefore what the apostle saith ought justly to be held sure and firm, that God worketh in us both to will and to do of his good pleasure. For there is no will nor understanding, conformable to the divine will and understanding, but what Christ hath wrought in man; which he teaches us, when he saith, Without me ye can do nothing.
