Where does the bible distinguish between a ruling elder and a teaching elder? All I can remember is that it just mentions elder and that title seems to be the same thing that many would call a bishop. All I remember seeing in there is elder and deacon. I can't remember where elder is divided into two parts.
1 Timothy 5:17
"Let the elders who rule well be considered worthy of double honor,
especially those who labor in preaching and teaching" (italics mine)
The distinction here is made between Elders and Preaching/Teaching Elders.
