Mark wrote: “but yet Paul says 2 chapters later in 5:17 that ‘elders who rule well are worthy of double honour, especially those who labour in preaching and teaching’. So the assumption is not all will teach yet they should be ‘able to teach’.
See the difference? IS this why you don’t like discussing elders because of Pauls correlation between them shepharding and preaching and teaching and that he only instructs men to take this resposibilty.”

Cheryl,
It appears to me that Mark continually overlooks the fact that in 1 Timothy 5:1-2 ‘presbutiro’ is used for both men and women – translated as “older men” and “older women.” In verse 17 the plural form, ‘presbutiboi’, is used of those who preach and teach in the church, and Paul tells Timothy that they are worthy of double honor. There is no reason to believe that this group was comprised of only men, especially since Paul had just used both the masculine and feminine form of the adjective in the first two verses of chapter 5.
So, ‘teacher’ and ‘elder’, whether apart or together, can be either men or women.
