Sometimes, there is no need to elaborate on a truth. It can speak for itself and allow those who see it to draw their own conclusions. The following excerpts from Early Church History to the Death of Constantine and The Teaching of the Twelve Apostles speak for themselves.
As regards the prophets and apostles moreover, according to the doctrine of the gospel, so do ye. Let every apostle who comes to you be received as the Lord: he will not remain with you [more than] one day; or if need be, the second day also; if he remain three days he is a false prophet. When the apostle departs, let him take nothing but bread enough to last till he reach his night quarters; if he ask for money he is a false prophet. And any prophet who speaks in the Spirit, ye shall not try nor test; for every sin shall be forgiven, but this sin shall not be forgiven. But not every one who speaks in the Spirit is a prophet, unless he have the behaviour of the Lord. From their behaviour therefore shall the false prophet and the prophet be known. No prophet who in the Spirit orders a table shall eat of it, otherwise he is a false prophet. Every prophet, though he teaches the truth, is a false prophet if he does not do what he teaches. Every approved true prophet who holds Church meetings for a worldly mystery, but does not teach [others] to do what he does, shall not be judged by you; for his judgment is with God; for the ancient prophets also did likewise. And whosoever shall say in the Spirit: Give me money, or anything else, ye shall not hearken to him; but if he tell you to give for others who are in need, let no man judge him. — The Teaching of the Twelve Apostles, chapter XI.
Instead of overseers (or bishops) and deacons, the corresponding passage in the Apostolical Constitutions has “bishops, presbyters, and deacons,” the offices having by this time become separated. The Gospel was preached by the traveling ministers, on the simple principle that the workman is worthy of his meat. “If,” says the Teaching, “the apostle should ask for money he is a false prophet.” — Edward Backhouse, Early Church History to the Death of Constantine, p. 119
