An elder, bishop, pastor-any church leader really-should preach the word (
2 Tim 2:4). Some believe that includes certain "standards".
They are to "reprove, rebuke and exhort". However, that quote doesn't equate to "blast, blast, blast."

(Sorry, pet peeve of mine.) Reproof is gentle correction. Rebuke is more "ye generation of vipers". Exhortation is uplifting and encouraging people to live for God.
They are to lead by example. (1 tim 3,
Titus 1, 1 Tim 4:12) Their families are actively involved in their ministry, as they are to have godly wives and children who are to lead by example as well. They are to be patient, slow to anger... in the New Testament, they were setting a course for the church of God. They were not to place undue restrictions on their people, however. (
1 Tim 4:3)
They are to teach (1 tim 3:2) and to preach (2 tim 4:2) Jesus. They are not there to lift up themselves or make a show of or by their buildings or their activities or lifestyles, but to walk humbly, giving honor to God as His servants. (Mt 6:1-6, Mt 23:11, 2 cor 4:5,
Acts 28:31...)
