It may seem unfair, but the pastor's family is, by the very qualifications of the pastor, put on a pedestal for all to see, and must live up to a higher expectation than the rest.
1 Timothy 3:1 This is a true saying, If a man desire the office of a bishop, he desireth a good work.
1 Timothy 3:2 A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach;
--He must be found blameless.
That word encompasses a lot. It means that his wife and children must act in a manner as not to bring blame or shame upon his ministry. It is not only the pastor himself that must avoid scandal, but it extends to his family, those living under his roof. If they cause scandal then the pastor is not blameless, and is disqualified from the ministry.
1 Timothy 3:4 One that ruleth well his own house, having his children in subjection with all gravity;
--His wife must be in submission to him. The Bible does not only speak of pastoral leadership and pastoral authority, but leadership and authority in the home. If the wife fails to submit the Biblical authority that God has placed in the home then she is rebelling, not only against her husband, but against God. The children (especially teens) can also disqualify a pastor by being in rebellion against their father. The Bible is clear. He must be one that rules his own house or he disqualifies himself from the ministry.
He must have his children in subjection.
1 Timothy 3:5 (For if a man know not how to rule his own house, how shall he take care of the church of God?)
--The reason is given here. If he can't even rule his own house, then how can he possibly rule the church of God? The answer is obvious.
The family is a sacred institution ordained of God. The Word of God likens it to the local church for which he died. In Ephesians chapter 5 he speaks about husbands loving their wives, and wives being in submission to their husbands. He then makes this statement.
Ephesians 5:25 Husbands, love your wives, even as Christ also loved the church, and gave himself for it;
--The family is put in contrast to the church, the church that Christ loved and died for. It ought not to be a bickering and unloving church, and thus the same goes for the family.
Ephesians 5:26-27 That he might sanctify and cleanse it with the washing of water by the word, That he might present it to himself a glorious church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish.
--The parallels are extended. Is this an apt illustration of our families?
Since salvation are we going through a process of sanctification and holiness, that someday, when the resurrection occurs we will be ready to meet our Lord. Of course we ought to be ready now. But our lives ought to be in a constant process of sanctification; our homes without spot or wrinkle or any such thing. Perhaps that is what Paul had in mind when he used the word "blameless."
