Ὃς ἂν οὖν ἐλθὼν διδάξῃ ὑμᾶς ταῦτα πάντα τὰ προειρημένα, δέξασθε αὐτόν· ἐὰν δὲ αὐτὸς ὁ διδάσκων στραφεὶς διδάσκῃ ἄλλην διδαχὴν εἰς τὸ καταλῦσαι, μὴ αὐτοῦ ἀκούσητε· εἰς δὲ τὸ προσθεῖναι δικαιοσύνην καὶ γνῶσιν κυρίου, δέξασθε αὐτὸν ὡς κύριον. περὶ δὲ τὼν ἀποστόλων καὶ προφητῶν, κατὰ τὰ δόγμα τοῦ εὐαγγελίου οὕτω ποιήσατε. πᾶς δὲ ἀπόστολος ἐρχόμενος πρὸς ὑμᾶς δεχθήτω ὡς κύριος· οὐ μενεῖ δὲ εἰ μὴ ἡμέραν μίαν· ἐὰν δὲ ᾖ χρεία, καὶ τὴν ἄλλην· τρεῖς δὲ ἐὰν μείνῃ, ψευδοπροφήτης ἐστίν. ἐξερχόμενος δὲ ὁ ἀπόστολος μηδὲν λαμβανέτω εἰ μὴ ἄρτον, ἕως οὗ αὐλισθῇ· ἐὰν δὲ ἀργύριον αἰτῇ, ψευδοπροφήτης ἐστί. καὶ πάντα προφήτην λαλοῦντα ἐν πνεύματι οὐ πειράσετε οὐδὲ διακρινεῖτε· πᾶσα γὰρ ἁμαρτία ἀφεθήσεται, αὕτη δὲ ἡ ἁμαρτία οὐκ ἀφεθήσεται. οὐ πᾶς δὲ ὁ λαλῶν ἐν πνεύματι προφήτης ἐστίν, ἀλλ’ ἐὰν ἔχῃ τοὺς τρόπους κυρίου. ἀπὸ οὖν τῶν τρόπων γνωσθήσεται ὁ ψευδοπροφήτης καὶ ὁ προφήτης. καὶ πᾶς προφήτης ὁρίζων τράπεζαν ἐν πνεύματι οὐ φάγεται ἀπ’ αὐτῆς, εἰ δὲ μήγε ψευδοπροφήτης ἐστί. πᾶς δὲ προφήτης διδάσκων τὴν ἀλήθειαν, εἰ ἃ διδάσκει οὐ ποιεῖ, ψευδοπροφήτης ἐστί. πᾶς δὲ προφήτης δεδοκιμασμένος, ἀληθινός, ποιῶν εἰς μυστήριον κοσμικὸν ἐκκλησίας, μὴ διδάσκων δὲ ποιεῖν, ὅσα αὐτὸς ποιεῖ, οὐ κριθήσεται ἐφ’ ὑμῶν· μετὰ θεοῦ γὰρ ἔχει τὴν κρίσιν· ὡσαύτως γὰρ ἐποίησαν καὶ οἱ ἀρχαῖοι προφῆται. ὃς δ’ ἂν εἴπῃ ἐν πνεύματι· δός μοι ἀργύρια ἢ ἕτερά τινα, οὐκ ἀκούσεσθε αὐτοῦ· ἐὰν δὲ περὶ ἄλλων ὑστερούντων εἴπῃ δοῦναι, μηδεὶς αὐτὸν κρινέτω.
(Didache 12)
Whosoever, therefore, comes and teaches you all these things that have been said before, receive him. But if the teacher himself turn and teach another doctrine to the destruction of this, hear him not; but if he teach so as to increase righteousness and the knowledge of the Lord, receive him as the Lord. But concerning the apostles and prophets, according to the decree of the Gospel, thus do. Let every apostle that comes to you be received as the Lord. But he shall not remain except one day; but if there be need, also the next; but if he remain three days, he is a false prophet. And when the apostle goes away, let him take nothing but bread until he lodges; but if he ask money, he is a false prophet. And every prophet that speaks in the Spirit you shall neither try nor judge; for every sin shall be forgiven, but this sin shall not be forgiven. But not every one that speaks in the Spirit is a prophet; but only if he hold the ways of the Lord. Therefore from their ways shall the false prophet and the prophet be known. And every prophet who orders a meal in the Spirit eats not from it, except indeed he be a false prophet; and every prophet who teaches the truth, if he do not what he teaches, is a false prophet. And every prophet, proved true, working unto the mystery of the Church in the world, yet not teaching others to do what he himself does, shall not be judged among you, for with God he has his judgment; for so did also the ancient prophets. But whoever says in the Spirit, Give me money, or something else, you shall not listen to him; but if he says to you to give for others’ sake who are in need, let no one judge him. (tr. Matthew Brown Riddle)
