Didache

Whosoever then comes and teaches you all[*](Travelling teachers) these things aforesaid, receive him.

But if the teacher himself be perverted and teach another doctrine to destroy these things, do not listen to him, but if his teaching be for the increase of righteousness and knowledge of the Lord, receive him as the Lord.

And concerning the Apostles and Prophets,[*](Apostles) act thus according to the ordinance of the Gospel.[*](It is unknown to what ordinance the writer refers.)

Let every Apostle who comes to you be received as the Lord,

but let him not stay more than one day, or if need be a second as well; but if he stay three days, he is a false prophet.

And when an Apostle goes forth let him accept nothing but bread till he reach his night’s lodging; but if he ask for money, he is a false prophet.

Do not test or examine any prophet who is speaking[*](Prophets) in a spirit, for every sin shall be forgiven, but this sin shall not be forgiven.
