In 1 Tim 3:2, Paul insists on an elder’s holiness in five major life categories: public, marital, family, personal and doctrinal. Paul sums up these areas with two words: above reproach. This is Paul’s way of saying that the elder should have no loopholes in his character.
Being above reproach means you have an unimpeachable character, but it doesn’t mean you are flawless. There’s a difference between having a bad day and having a bad year; the elder should live in such a way as to be accusation-free and without any sustained or legitimate patterns of sin.
