A traveling prophet had no problem being accepted for this reason. They would go without purse and depend on the Lord completely for their provision. I believe that it is out of order for any other but the prophets to judge prophecy but clarification is needed. Many time prophets today take too much authority upon themselves as if they are to be the watchman of everything that goes on. They can be meddlesome at times and interfere without thought of proper edification but spout off just to get attention and show off their gift.
Discernment of spirits is a prophetic gift, so is the interpretation of tongues.
Preaching in the spirit is a prophetic gift, charismatic teaching is also, so just having the office of a prophet does not necessarily make the prophet some kind of judge over what others say unless it is is the spirit of prophecy and in its proper order. Without the spirit of prophecy, the prophets as a particular office have no function and it is all the same spirit no matter what the gift. We can have multiple gifts, there are apostolic prophets and prophetic teachers and those who speak in tongues and interpret. We cannot lock anyone into any particular gift and say that this is their gift and one cannot operate in others, it is not our job to do that, it is the Lord's. We cannot elevate prophecy but the Lord has and has reminded us that the testimony of Jesus is the spirit of prophecy.
