I want to make quite clear to you, brothers, what the message of the gospel that I preached to you is; you accepted it and took your stand on it, 2 and you are saved by it, if you keep to the message I preached to you; otherwise your coming to believe was in vain.
3 The tradition I handed on to you in the first place, a tradition which I had myself received, was that Christ died for our sins, in accordance with the scriptures, 4 and that he was buried; and that on the third day, he was raised to life, in accordance with the scriptures; 5 and that he appeared to Cephas; and later to the Twelve; 6 and next he appeared to more than five hundred of the brothers at the same time, most of whom are still with us, though some have fallen asleep; 7 then he appeared to James, and then to all the apostles. 8 Last of all he appeared to me too, as though I was a child born abnormally. 9 For I am the least of the apostles and am not really fit to be called an apostle, because I had been persecuting the Church of God; 10 but what I am now, I am through the grace of God, and the grace which was given to me has not been wasted. Indeed, I have worked harder than all the others — not I, but the grace of God which is with me.
11 Anyway, whether it was they or I, this is what we preach and what you believed. 12 Now if Christ is proclaimed as raised from the dead, how can some of you be saying that there is no resurrection of the dead? 13 If there is no resurrection of the dead, then Christ cannot have been raised either, 14 and if Christ has not been raised, then our preaching is without substance, and so is your faith.
15 What is more, we have proved to be false witnesses to God, for testifying against God that he raised Christ to life when he did not raise him — if it is true that the dead are not raised. 16 For, if the dead are not raised, neither is Christ; 17 and if Christ has not been raised, your faith is pointless and you have not, after all, been released from your sins. 18 In addition, those who have fallen asleep in Christ are utterly lost. 19 If our hope in Christ has been for this life only, we are of all people the most pitiable. 20 In fact, however, Christ has been raised from the dead, as the first-fruits of all who have fallen asleep.

*Γνωρίζω δὲ ὑμῖν, ἀδελφοί, τὸ εὐαγγέλιον ὃ εὐηγγελισάμην ὑμῖν, ὃ καὶ παρελάβετε, ἐν ᾧ καὶ ἑστήκατε, 2 δι᾽ οὗ καὶ σῴζεσθε, τίνι λόγῳ εὐηγγελισάμην ὑμῖν εἰ κατέχετε, ἐκτὸς εἰ μὴ εἰκῇ ἐπιστεύσατε. 3 παρέδωκα γὰρ ὑμῖν ἐν πρώτοις, ὃ καὶ παρέλαβον, ὅτι Χριστὸς ἀπέθανεν ὑπὲρ τῶν ἁμαρτιῶν ἡμῶν κατὰ τὰς γραφὰς 4 καὶ ὅτι ἐτάφη καὶ ὅτι ἐγήγερται τῇ ἡμέρᾳ τῇ τρίτῃ κατὰ τὰς γραφὰς 5 καὶ ὅτι ὤφθη Κηφᾷ εἶτα τοῖς δώδεκα· 6 ἔπειτα ὤφθη ἐπάνω πεντακοσίοις ἀδελφοῖς ἐφάπαξ, ἐξ ὧν οἱ πλείονες μένουσιν ἕως ἄρτι, τινὲς δὲ ἐκοιμήθησαν· 7 ἔπειτα ὤφθη Ἰακώβῳ εἶτα τοῖς ἀποστόλοις πᾶσιν· 8 ἔσχατον δὲ πάντων ὡσπερεὶ τῷ ἐκτρώματι ὤφθη κἀμοί. 9 Ἐγὼ γάρ εἰμι ὁ ἐλάχιστος τῶν ἀποστόλων ὃς οὐκ εἰμὶ ἱκανὸς καλεῖσθαι ἀπόστολος, διότι ἐδίωξα τὴν ἐκκλησίαν τοῦ θεοῦ· 10 χάριτι δὲ θεοῦ εἰμι ὅ εἰμι, καὶ ἡ χάρις αὐτοῦ ἡ εἰς ἐμὲ οὐ κενὴ ἐγενήθη, ἀλλὰ περισσότερον αὐτῶν πάντων ἐκοπίασα, οὐκ ἐγὼ δὲ ἀλλὰ ἡ χάρις τοῦ θεοῦ [ἡ] σὺν ἐμοί. 11 εἴτε οὖν ἐγὼ εἴτε ἐκεῖνοι, οὕτως κηρύσσομεν καὶ οὕτως ἐπιστεύσατε. 12 Εἰ δὲ Χριστὸς κηρύσσεται ὅτι ἐκ νεκρῶν ἐγήγερται, πῶς λέγουσιν ἐν ὑμῖν τινες ὅτι ἀνάστασις νεκρῶν οὐκ ἔστιν; 13 εἰ δὲ ἀνάστασις νεκρῶν οὐκ ἔστιν, οὐδὲ Χριστὸς ἐγήγερται· 14 εἰ δὲ Χριστὸς οὐκ ἐγήγερται, κενὸν ἄρα [καὶ] τὸ κήρυγμα ἡμῶν, κενὴ καὶ ἡ πίστις ὑμῶν· 15 εὑρισκόμεθα δὲ καὶ ψευδομάρτυρες τοῦ θεοῦ, ὅτι ἐμαρτυρήσαμεν κατὰ τοῦ θεοῦ ὅτι ἤγειρεν τὸν Χριστόν, ὃν οὐκ ἤγειρεν εἴπερ ἄρα νεκροὶ οὐκ ἐγείρονται. 16 εἰ γὰρ νεκροὶ οὐκ ἐγείρονται, οὐδὲ Χριστὸς ἐγήγερται· 17 εἰ δὲ Χριστὸς οὐκ ἐγήγερται, ματαία ἡ πίστις ὑμῶν, ἔτι ἐστὲ ἐν ταῖς ἁμαρτίαις ὑμῶν, 18 ἄρα καὶ οἱ κοιμηθέντες ἐν Χριστῷ ἀπώλοντο. 19 εἰ ἐν τῇ ζωῇ ταύτῃ ἐν Χριστῷ ἠλπικότες ἐσμὲν μόνον, ἐλεεινότεροι πάντων ἀνθρώπων ἐσμέν. 20 Νυνὶ δὲ Χριστὸς ἐγήγερται ἐκ νεκρῶν ἀπαρχὴ τῶν κεκοιμημένων.
