Thomas Aquinas

“ But in nature there is no active principle of the resurrection, neither as regards the union of the soul with the body, nor as regards the disposition which is the demand for that union: since such a disposition cannot be produced by nature, except in a definite way by the process of generation from seed. Wherefore even granted a passive potentiality on the part of the body, or any kind of inclination to its union with the soul, it is not such as to suffice for the conditions of natural movement. ”

“ And since to the worker is due the reward of the work, it behooves man himself, who is composed of soul and body, to receive the reward of his work. Now as venial offenses are called sins as being dispositions to sin, and not as having simply and perfectly the character of sin, so the punishment which is awarded to them in purgatory is not a retribution simply, but rather a cleansing, which is wrought separately in the body, by death and by its being reduced to ashes, and in the soul by the fire of purgatory. ”

“ For certain heretics asserted that all bodily things are from the evil principle, but that spiritual things are from the good principle: and from this it follows that the soul cannot reach the height of its perfection unless it be separated from the body, since the latter withdraws it from its principle, the participation of which makes it happy. Hence all those heretical sects that hold corporeal things to have been created or fashioned by the devil deny the resurrection of the body. ”

“ Therefore separation from the body is its final state, and consequently it returns not from this state to the body, as neither does a man end in becoming a boy.
Objection 5: Further, bodily death is the punishment inflicted on man for his own transgression, as appears from Gn. 2, even as spiritual death, which is the separation of the soul from God, is inflicted on man for mortal sin. Now man never returns to life from spiritual death after receiving the sentence of his damnation. Therefore neither will there be any return from bodily death to bodily life, and so there will be no resurrection. ”

“ Other things being equal, the state of the soul in the body is more perfect than outside the body, because it is a part of the whole composite; and every integral part is material in comparison to the whole: and though it were conformed to God in one respect, it is not simply. Because, strictly speaking, a thing is more conformed to God when it has all that the condition of its nature requires, since then most of all it imitates the Divine perfection. ”

“ Those who have died in original sin have, by dying, discharged the obligation of death which is the punishment of original sin. Hence, notwithstanding original sin, they can rise again from death: for the punishment of original sin is to die, rather than to be detained by death. ”

“ Now the most perfect state of the soul is to be separated from the body, since in that state it is more conformed to God and the angels, and is more pure, as being separated from any extraneous nature. ”

“ Accordingly the action or movement that is related to nature in the first way can nowise be natural, but is either miraculous if it come from a principle above nature, or violent if from any other principle. The action or movement that is related to nature in the second way is simply natural: but the action that is related to nature in the third way cannot be described as natural simply, but as natural in a restricted sense, in so far, to wit, as it leads to that which is according to nature: but it is called either miraculous or artificial or violent. ”

“ Hence life in Abraham's soul does not suffice to make Abraham a living being, or to make the God of Abraham the God of a living man. But there needs to be life in the whole composite, i.e. the soul and body: and although this life were not actually when these words were uttered, it was in each part as ordained to the resurrection. Wherefore our Lord proves the resurrection with the greatest subtlety and efficacy. ”

“ The soul is compared to the body, not only as a worker to the instrument with which he works, but also as form to matter: wherefore the work belongs to the composite and not to the soul alone, as the Philosopher shows (De Anima i, 4) . ”

“ We are born again by the grace of Christ that is given to us, but we rise again by the grace of Christ whereby it came about that He took our nature, since it is by this that we are conformed to Him in natural things. Hence those who die in their mother's womb, although they are not born again by receiving grace, will nevertheless rise again on account of the conformity of their nature with Him, which conformity they acquired by attaining to the perfection of the human species. ”

“ Such is not the resurrection, and hence the argument is not to the point.
Reply to Objection 4: The entire operation of nature is subordinate to the Divine operation, just as the working of a lower art is subordinate to the working of a higher art. Hence just as all the work of a lower art has in view an end unattainable save by the operation of the higher art that produces the form, or makes use of what has been made by art: so the last end which the whole expectation of nature has in view is unattainable by the operation of nature, and for which reason the attaining thereto is not natural. ”

“ And there is another movement whereof nature is the term, but not the principle, the latter being sometimes something above nature (as in giving sight to a blind man, for sight is natural, but the principle of the sight-giving is above nature) , and sometimes something else, as in the forcing of flowers or fruit by artificial process. It is impossible for nature to be the principle and not the term, because natural principles are appointed to definite effects, beyond which they cannot extend. ”

“ Further, things that are against nature abide not for long, because they are violent, so to speak. But the life that is restored by the resurrection will last for ever. Therefore the resurrection will be natural. ”

“ All, both good and wicked, are conformed to Christ, while living in this life, as regards things pertaining to the nature of the species, but not as regards matters pertaining to grace. Hence all will be conformed to Him in the restoration of natural life, but not in the likeness of glory, except the good alone. ”

“ Further, the resurrection is necessary in order that those who rise again may receive punishment or reward according to their merits. Now either punishment or reward is due to all, either for their own merits, as to adults, or for others' merits, as to children. ”

“ The passive principle of natural generation is the natural passive potentiality which always has an active principle corresponding to it in nature, according to Metaphysics viii, 1: nor as to this does it matter whether the active principle in nature correspond to the passive principle in respect of its ultimate perfection, namely the form ”

“ Or else the restriction may refer to the children consigned to limbo who, although they shall rise again, are not properly said to awake, since they will have no sense either of pain or of glory, and waking is the unchaining of the senses. ”
