Paul the Apostle admonished Timothy, who was also a teacher in the Church of God, not to rebuke elders. Not because elders have done something wrong they should be rebuked right away. No, they should be respected because we are to respect our elders. We are to respect our parents. So if an elderly person does something wrong. We should not rebuke him or her right away, but we should respectfully point out what they have done wrong. So that they were able to take corrections.
We must be respectful all the time because this is what is written in the bible that was clearly explained by brother Eli.
