A portion of the Acts of Paul and Thecla (translation by M.R. James, modified slightly)
For there were certain men come to Corinth, Simon and Cleobius, saying: There is no resurrection of the flesh, but that of the spirit only: and that the body of man is not the creation of God; and also concerning the world, that God did not create it, and that God knoweth not the world, and that Jesus Christ was not crucified, but it was an appearance (i.e. but only in appearance), and that lie was not born of Mary, nor of the seed of David. And in a word, there were many things which they had taught in Corinth, deceiving many other men, (and deceiving also) themselves. When therefore the Corinthians heard that Paul was at Philippi, they sent a letter unto Paul to Macedonia by Threptus and Eutychus the deacons. And the letter was after this manner.
I. 1 Stephanus and the elders (presbyters) that are with him, even Daphnus and Eubulus and Theophilus and Zenon, unto Paul their brother in the Lord, greetings.
2 There have come to Corinth two men, Simon and Cleobius, which are overthrowing the faith of many with evil words. 3 These you shall examine yourselves: 4 for we have never heard such words from you nor from the other apostles: 5 but all that we have received from you or from them [the other apostles], to that we hold fast. 6 Since therefore the Lord has had mercy on us, that while you art still in the flesh we may hear these things again from thee, 7 if it be possible, either come unto us or write unto us. 8 For we believe, according as it has been revealed to Theonoe, that the Lord hath delivered thee out of the hand of the lawless one.
9 Now the things which these men say and teach are these: 10 They say that we must not use the prophets, 11 and that God is not Almighty, 12 and that there shall be no resurrection of the flesh, 13 and that man was not made by God, 14 and that Christ came not down in the flesh, neither was born of Mary, 15 and that the world is not made by God, but by the angels.
16 Wherefore, brother, use all diligence to come unto us, that the church of the Corinthians may remain without offence, and the madness of these men may be made plain. Farewell in the Lord.
II. 1 The deacons Threptus and Eutyches brought the letter unto Philippi, 2 so that Paul received it, being in bonds because of Stratonice the wife of Apollophanes, and was very sad, 3 and cried out, saying: It were better for me to die and to be with the Lord, than to continue in the flesh and to hear such things so that trouble cometh upon trouble. 4 And over and above this so great sadness I am in bonds and behold these evils whereby the devices of Satan are accomplished. 5 Paul therefore, in great affliction, wrote a letter, answering thus:
III.1 Paul, a prisoner of Jesus Christ, unto the brethren which are in Corinth, greeting.
2 Being in the midst of many tribulations, I marvel not if the teachings of the evil one run abroad apace. 3 For my Lord Jesus Christ will hasten his coming, and will set at nought (no longer endure the insolence of) them that falsify his words.
4 For I delivered unto you in the beginning the things which I received of the apostles which were before me, who were at all times with Jesus Christ: 5 namely, that our Lord Jesus Christ was born of Mary of the seed of David, the Holy Ghost being sent forth from heaven from the Father unto her , 6 that he might come down into this world and redeem all flesh by his flesh, and raise us up from the dead in the flesh, like as he hath shown to us in himself for an ensample. 7 And because man was formed by his Father, 8 therefore was he sought when he was lost, that he might be quickened by adoption. 9 For to this end did God Almighty who made heaven and earth first send the prophets unto the Jews, that they might be drawn away from their sins. 10 For he designed to save the house of Israel: therefore he conferred a portion of the spirit of Christ upon the prophets and sent them unto the Jews first (or unto the first Jews), and they proclaimed the true worship of God for a long space of time. 11 But the prince of iniquity, desiring to be God, laid hands on them and slew them, and bound all flesh by evil lusts.
12 But God Almighty, who is righteous, would not cast away his own creation, and sent his spirit into Mary the Galilean, 15 that by that flesh whereby that wicked one had brought in death (had triumphed), by the same he should be shown to be overcome. 16 For by his own body Jesus Christ saved all flesh, 17 that he might show forth the temple of righteousness in his body. 18 In whom (or whereby) we are saved.
19 They therefore are not children of righteousness but children of wrath who reject the wisdom (providence?) of God, saying that the heaven and the earth and all that are in them are not the work of God. 20 The are cursed, following the teaching of the serpent, 21 whom do you drive out from you and flee from their doctrine.
24 And as for that which they say, that there is no resurrection of the flesh, they indeed shall have no resurrection, 25 because they believe not in him that is risen from the dead, 26 for they know not, O Corinthians, the seeds of wheat or of other seeds (grain), how they are cast bare into the earth and are corrupted and rise again by the will of God with bodies, and clothed. 27 And not only that [body] which is cast in rises again, but manifold more blessing itself [i.e. fertile and prospering]. 28 And if we must not take an example from seeds. 29 You know how Jonah the son of Amathios, when he would not preach to them of Nineveh, was swallowed by the sea-monster; 30 and after three days and three nights God heard the prayer of Jonah out of the lowest hell, and no part of him was consumed, not even an hair nor an eyelash. 31 How much more, shall he raise up you that have believed in Christ Jesus, like as he himself arose. 32 Likewise also a dead man was cast upon the bones of the prophet Helisaetis by the children of Israel, and he arose, both body and soul and bones and spirit; how much more shall you which have been cast upon the body and bones and spirit of the Lord
34 If, however you receive any other doctrine, let no man trouble me, 35 for I bear these bonds that I may win Christ, and I therefore bear his marks in my body that I may attain unto the resurrection of the dead. 86 And whoso receiveth (abideth in) the rule which he hath received by the blessed prophets and the holy gospel, shall receive a recompense from the Lord. 37 But who so transgresses these things, with him is the fire, and with them that walk in like manner , 38 which are a generation of vipers, 39 whom you reject in the power of the Lord. 40 Peace shall be with you.
