Faith is received through the Church

But such spirits as are commanded by these men, and speak when they desire it, are earthly and weak, audacious and impudent, sent forth by Satan for the seduction and perdition of those who do not hold fast that well-compacted faith which they received at first through the Church.

Irenaeus of Lyons
Against Heresies Book I
Chapter XIII

No one adds or removes from the tradition of the Church

Nor will any one of the rulers in the Churches, however highly gifted he may be in point of eloquence, teach doctrines different from these (for no one is greater than the Master); nor, on the other hand, will he who is deficient in power of expression inflict injury on the tradition. For the faith being ever one and the same, neither does one who is able at great length to discourse regarding it, make any addition to it, nor does one, who can say but little diminish it.

Irenaeus of Lyons

The Church hands down the tradition that has been preserved from the Apostles

As I have already observed, the Church, having received this preaching and this faith, although scattered throughout the whole world, yet, as if occupying but one house, carefully preserves it. She also believes these points [of doctrine] just as if she had but one soul, and one and the same heart, and she proclaims them, and teaches them, and hands them down, with perfect harmony, as if she possessed only one mouth. For, although the languages of the world are dissimilar, yet the import of the tradition is one and the same. For the Churches which have been planted in Germany do not believe or hand down anything different, nor do those in Spain, nor those in Gaul, nor those in the East, nor those in Egypt, nor those in Libya, nor those which have been established in the central regions of the world.

The Apostolic Faith (similar to creeds)

The Church, though dispersed through our the whole world, even to the ends of the earth, has received from the apostles and their disciples this faith: [She believes] in one God, the Father Almighty, Maker of heaven, and earth, and the sea, and all things that are in them; and in one Christ Jesus, the Son of God, who became incarnate for our salvation; and in the Holy Spirit, who proclaimed through the prophets the dispensations of God, and the advents, and the birth from a virgin, and the passion, and the resurrection from the dead, and the ascension into heaven in the flesh of the beloved Christ Jesus, our Lord, and His [future] manifestation from heaven in the glory of the Father “to gather all things in one,” and to raise up anew all flesh of the whole human race, in order that to Christ Jesus, our Lord, and God, and Savior, and King, according to the will of the invisible Father, “every knee should bow, of things in heaven, and things in earth, and things under the earth, and that every tongue should confess” to Him, and that He should execute just judgment towards all; that He may send “spiritual wickednesses,” and the angels who transgressed and became apostates, together with the ungodly, and unrighteous, and wicked, and profane among men, into everlasting fire; but may, in the exercise of His grace, confer immortality on the righteous, and holy, and those who have kept His commandments, and have persevered in His love, some from the beginning [of their Christian course], and others from [the date of] their repentance, and may surround them with everlasting glory.

Resurrection is of the same flesh that died

The resurrection is a resurrection of the flesh which died. For the spirit dies not; the soul is in the body, and without a soul it cannot live. The body, when the soul forsakes it, is not. For the body is the house of the soul; and the soul the house of the spirit. These three, in all those who cherish a sincere hope and unquestioning faith in God, will be saved.

Justin Martyr
Fragments from the Lost Work of Justin on the Resurrection
Chapter X

Resurrection is a restoration of the same flesh

They who maintain the wrong opinion say that there is no resurrection of the flesh; giving as their reason that it is impossible that what is corrupted and dissolved should be restored to the same as it had been. And besides the impossibility, they say that the salvation of the flesh is disadvantageous; and they abuse the flesh, adducing its infirmities, and declare that it only is the cause of our sins, so that if the flesh, say they, rise again, our infirmities also rise with it. And such sophistical reasons as the following they elaborate: If the flesh rise again, it must rise either entire and possessed of all its parts, or imperfect. But its rising imperfect argues a want of power on God’s part, if some parts could be saved, and others not; but if all the parts are saved, then the body will manifestly have all its members. But is it not absurd to say that these members will exist after the resurrection from the dead, since the Savior said, “They neither marry, nor are given in marriage, but shall be as the angels in heaven?” And the angels, say they, have neither flesh, nor do they eat, nor have sexual intercourse; therefore there shall be no resurrection of the flesh. By these and such like arguments, they attempt to distract men from the faith.

The Word of truth is God

Now the word of truth is sent from God; wherefore the freedom claimed by the truth is not arrogant. For being sent with authority, it were not fit that it should be required to produce proof of what is said; since neither is there any proof beyond itself, which is God.
