With regard to the Scriptures, the Word of God which abides forever -- we should do as the Bereans; we should "search the Scriptures daily" to see whether what we are told is true or not.
With regard to "rules", perhaps we need to abide by the "rules" ... but sometimes the interpretation of the rules is not the "best" for small rural churches.
We are advised to just "go with the flow". That may be the easiest.
Like the salmon?
If they just "go with the flow", though, soon there won't be many salmon!!
