So, we Christians have all been in the situation where we are either sitting under the guidance of or know of a pastor who is teaching bad or wrong doctrine. What is our obligation as "laymen"? Perhaps it depends on the severity of the bad doctrine. Maybe we will be told that we would need to go through an official process such as an elder board, but not all church structures even have an elder board. Sometimes the pastor is the end of line.
Scripture says:
"Do not entertain an accusation against an elder unless it is brought by two or three witnesses." -- 1 Tim 5:19
But is this really speaking of challenging a pastor on bad doctrine or rather on bad behavior. Verse 20 goes on to say:
"But those elders who are sinning you are to reprove before everyone, so that the others may take warning." -- 1 Tim 5:20
So, clearly the "accusation against an elder" is in reference to his sinning.
