No! and it would be questionable if one should ever be allowed to return as a teacher.
Romans and Galatians describe the seriousness of the sins you listed:
Rom 13:12-14 … let us therefore cast off the works of darkness, and let us put on the armour of light. (13) Let us walk honestly, as in the day; not in rioting and drunkenness, not in chambering and wantonness, not in strife and envying. (14) But put ye on the Lord Jesus Christ, and make not provision for the flesh, to fulfil the lusts thereof.
See verse 13 in another version:(CEV) So behave properly, as people do in the day. Don't go to wild parties or get drunk or be vulgar or indecent. Don't quarrel or be jealous.
Gal 5:19 Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness, (20) Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, (21) Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
Mat 3:7-8 But when he saw many of the Pharisees and Sadducees come to his baptism, he said unto them, O generation of vipers, who hath warned you to flee from the wrath to come? (8) Bring forth therefore fruits meet for repentance:
The Scribes and Pharisees were the men of God, they are like the ministers and priests of today. Jesus tells us they were hypocrites, so when they came to John to be baptized, he told them they needed to bring fruits of their repentance. What does that mean? It means saying I am sorry is not enough. They had to prove it was more than just lip service. They had a lifestyle that was not in harmony with the God they said they served. Nobody changes over night.
When one of the body members of Christ engages in sin, it is bad enough, but being an elder brings it to a whole different level. An elder represents the congregation and so he must be above reproach and faithful in all things. If he is unfaithful to his wife, he will be unfaithful to God as well.
Qualifications to be a teacher/elder
Mat 5:19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
Tit 1:5-8 … ordain elders in every city, as I had appointed thee: (6) If any be blameless, the husband of one wife, having faithful children not accused of riot or unruly. (7) For a bishop must be blameless, as the steward of God; not selfwilled, not soon angry, not given to wine, no striker, not given to filthy lucre; (8) But a lover of hospitality, a lover of good men, sober, just, holy, temperate;
1Ti 3:2-7 A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach; (3) Not given to wine, no striker, not greedy of filthy lucre; but patient, not a brawler, not covetous; (4) One that ruleth well his own house, having his children in subjection with all gravity; (5) (For if a man know not how to rule his own house, how shall he take care of the church of God?) (6) Not a novice, lest being lifted up with pride he fall into the condemnation of the devil. (7) Moreover he must have a good report of them which are without; lest he fall into reproach and the snare of the devil.
If he has given the fruits of repentance and is forgiven, does he still qualify for the position of elder of the congregation? No, he does not. He is not the blameless husband of one wife, In Timothy it says “He MUST have a good report of them that are without. If he is guilty of the things listed in the question then he fails on these points.
If one were to do such things and subsequently feel they were a suitable candidate for a teaching or leadership position in the Church it would be a strong indicator they were NOT repentant and were likely NOT qualified for such a position. Failing that, it is the responsibility of the CHURCH to prohibit such an one from occupying any office whereby they may influence or are an example to others. It would be to the Church’s SHAME to allow or promote any such individual to hold any office.
Only after significant time has passed (a number of years) without relapse and having demonstrated sufficient character and ability to lead and teach should he be even remotely considered to be qualified for the office of elder
