I believe in the example above, the preacher could be restored to fellowship, but we have Scriptures that teach his authority in the Church will not be restored. People in leadership are held to a higher standard, and are their accountability to God and the congregation is greater. They have to be men of dignity, above reproach, and faithful in all things. Sin has consequences, esp. for people in leadership roles in the Church.
Titus 1,
5For this reason I left you in Crete, that you would set in order what remains and
appoint elders in every city as I directed you,
6namely, if any man is above reproach, the husband of one wife, having children who believe, not accused of dissipation or rebellion.
7For the overseer must be above reproach as God’s steward, not self-willed, not quick-tempered, not addicted to wine, not pugnacious, not fond of sordid gain,
8but hospitable, loving what is good, sensible, just, devout, self-controlled,
9holding fast the faithful word which is in accordance with the teaching, so that he will be able both to exhort in sound doctrine and to refute those who contradict.
1st Tim 3,
1It is a trustworthy statement: if any man aspires to the
office of overseer, it is a fine work he desires
to do. 2An overseer, then,
must be above reproach, the husband of one wife, temperate, prudent, respectable, hospitable, able to teach,
3not addicted to wine or pugnacious, but gentle, peaceable, free from the love of money.
4He must be one who manages his own household well, keeping his children under control with all dignity
5(but if a man does not know how to manage his own household, how will he take care of the church of God?),
6and not a new convert, so that he will not become conceited and fall into the condemnation incurred by the devil.
7And he
must have a good reputation with those outside the church, so that he will not fall into reproach and the snare of the devil.
8Deacons likewise must be men of dignity, not double-tongued, or addicted to much wine or fond of sordid gain,
9but holding to the mystery of the faith with a clear conscience.
10These men must also first be tested; then let them serve as deacons if they are beyond reproach.
11Women
must likewise
be dignified, not malicious gossips, but temperate,
faithful in all things. 12Deacons must be husbands of
only one wife,
and good managers of
their children and their own households.
13For those who have served well as deacons obtain for themselves a high standing and great confidence in the faith that is in Christ Jesus.
1st Tim 5,
17The elders who rule well are to be considered worthy of double honor, especially those who work hard at preaching and teaching.
18For the Scripture says, “YOU SHALL NOT MUZZLE THE OX WHILE HE IS THRESHING,” and “The laborer is worthy of his wages.”
19Do not receive an accusation against an elder except on the basis of two or three witnesses. 20Those who continue in sin, rebuke in the presence of all, so that the rest also will be fearful of sinning. 21I solemnly charge you in the presence of God and of Christ Jesus and of
His chosen angels, to maintain these
principles without bias, doing nothing in a
spirit of partiality.
22Do not lay hands upon anyone
too hastily and thereby share
responsibility for the sins of others; keep yourself free from sin.
