The body is raised to be judged according to its deeds

But if each of these things belongs to man by nature, and he requires food for his life, and requires posterity for the continuance of the race, and requires a judgment in order that food and posterity may be according to law, it of course follows, since food and posterity refer to both together, that the judgment must be referred to them too (by both together I mean man, consisting of soul and body), and that such man becomes accountable for all his actions, and receives for them either reward or punishment. Now, if the righteous judgment awards to both together its retribution for the deeds wrought; and if it is not proper that either the soul alone should receive the wages of the deeds wrought in union with the body…

Athenagoras of Athens
The Resurrection of the Dead
Chapter XVIII

Resurrected bodies are composed of body and soul

For whatever has been created for the sake of something else, when that has ceased to be for the sake of which it was created, will itself also fitly cease to be, and will not continue to exist in vain, since, among the works of God, that which is useless can have no place; but that which was created for the very purpose of existing and living a life naturally suited to it, since the cause itself is bound up with its nature, and is recognized only in connection with existence itself, can never admit of any cause which shall utterly annihilate its existence. But since this cause is seen to lie in perpetual existence, the being so created must be preserved for ever, doing and experiencing what is suitable to its nature, each of the two parts of which it consists contributing what belongs to it, so that the soul may exist and remain without change in the nature in which it was made, and discharge its appropriate functions (such as presiding over the impulses of the body, and judging of and measuring that which occurs from time to time by the proper standards and measures), and the body be moved according to its nature towards its appropriate objects, and undergo the changes allotted to it, and, among the rest (relating to age, or appearance, or size), the resurrection. For the resurrection is a species of change, and the last of all, and a change for the better of what still remains in existence at that time.

Athenagoras of Athens
The Resurrection of the Dead
Chapter XII

Resurrected bodies no longer need nourishment

…for the bodies that rise again are reconstituted from the parts which properly belong to them, whereas no one of the things mentioned is such a part, nor has it the form or place of a part; nay, it does not remain always with the parts of the body which are nourished, or rise again with the parts that rise, since no longer does blood, or phlegm, or bile, or breath, contribute anything to the life. Neither, again, will the bodies nourished then require the things they once required, seeing that, along with the want and corruption of the bodies nourished, the need also of those things by which they were nourished is taken away.

Athenagoras of Athens
The Resurrection of the Dead
Chapter VII

God will gather again the bodies that are dead

It behoves, therefore, those who disbelieve or doubt concerning the resurrection, to form their opinion on the subject, not from any view they have hastily adopted, and from what is acceptable to profligate men, but either to assign the origin of men to no cause (a notion which is very easily refuted), or, ascribing the cause of all things to God, to keep steadily in view the principle involved in this article of belief, and from this to demonstrate that the resurrection is utterly unworthy of credit. This they will succeed in, if they are able to show that it is either impossible for God, or contrary to His will, to unite and gather together again bodies that are dead, or even entirely dissolved into their elements, so as to constitute the same persons.

Athenagoras of Athens
The Resurrection of the Dead
Chapter II

Resurrected bodies are constructed from the very same elements

But if to any one it appears sheer nonsense that the body which has mouldered away, and been dissolved, and reduced to nothing, should be reconstructed, we certainly cannot with any reason be accused of wickedness with reference to those that believe not, but only of folly;

…for nothing hinders, according to Pythagoras and Plato, that when the dissolution of bodies takes place, they should, from the very same elements of which they were constructed at first, be constructed again. But let us defer the discourse concerning the resurrection.

Athenagoras of Athens
A Plea for the Christians
Chapter XXXVI

The new flesh of the resurrection is the same as the old flesh

He promised to drink of the fruit of the vine with His disciples, thus indicating both these points: the inheritance of the earth in which the new fruit of the vine is drunk, and the resurrection of His disciples in the flesh. For the new flesh which rises again is the same which also received the new cup.

Irenaeus of Lyons
Against Heresies, Book V
Chapter XXXIII

No soul sleep before the resurrection

For as the Lord “went away in the midst of the shadow of death,” where the souls of the dead were, yet afterwards arose in the body, and after the resurrection was taken up [into heaven], it is manifest that the souls of His disciples also, upon whose account the Lord underwent these things, shall go away into the invisible place allotted to them by God, and there remain until the resurrection, awaiting that event; then receiving their bodies, and rising in their entirety, that is bodily, just as the Lord arose, they shall come thus into the presence of God.

Irenaeus of Lyons
Against Heresies, Book V
Chapter XXXII

 

After the invocation, the bread is no longer common bread

Then, again, how can they say that the flesh, which is nourished with the body of the Lord and with His blood, goes to corruption, and does not partake of life? Let them, therefore, either alter their opinion, or cease from offering the things just mentioned. But our opinion is in accordance with the Eucharist, and the Eucharist in turn establishes our opinion. For we offer to Him His own, announcing consistently the fellowship and union of the flesh and Spirit. For as the bread, which is produced from the earth, when it receives the invocation of God, is no longer common bread, but the Eucharist, consisting of two realities, earthly and heavenly; so also our bodies, when they receive the Eucharist, are no longer corruptible, having the hope of the resurrection to eternity.

Irenaeus of Lyons
Against Heresies, Book IV
Chapter XVIII

Souls continue to exist after death

For if He be not the God of the dead, but of the living, yet was called the God of the fathers who were sleeping, they do indubitably live to God, and have not passed out of existence, since they are children of the resurrection.

Irenaeus of Lyons
Against Heresies, Book IV
Chapter V
