Peter encourages elders in 1 Peter 5:2 to ποιμάνατε (be shepherds). Paul instructs Timothy to install elders with qualifications listed in 1 Timothy 3:2 that include διδακτικόν (apt to teach). In Ephesians 4:11 Paul lists the gifts Christ gave to men for the equipping of the saints and he uses the noun forms of the above verbs to identify the final gift in the list as ποιμένας και διδασκάλους. Are there any historical references indicating that those gifted as shepherds and teachers are synonymous with the elders appointed in the early church? Basically, would it be appropriate to read it as "some apostles, some prophets, some evangelists, and some overseers"?
