My simple answer is NO he is not qualified to be a Pastor/Elder/Minister. The word of God is very clear in 1 Timothy verse 2. The bible says the husband of 1 wife.
1Ti 3:1-7 Faithful is the Word: If anyone reaches out to overseership, he desires a good work. (2) Then it behooves the overseer to be without reproach, husband of one wife, temperate, sensible, well-ordered, hospitable, apt at teaching, (3) not a drunkard, not contentious, not greedy of ill gain, but gentle, not quarrelsome, not covetous, (4) ruling his own house well, having children in subjection with all honor. (5) (For if a man does not know to rule his own house, how shall he take care of the church of God?) (6) not a novice, lest being puffed up he may fall into the condemnation of the Devil. (7) But he must also have a good report from those on the outside, lest he fall into reproach and the snare of the Devil.
Then we move on to Titus
Tit 1:5-9 For this cause I left you in Crete, that you should set in order the things that are lacking and ordain elders in every city, as I had appointed you, (6) if anyone is blameless, husband of one wife, having believing children, not accused of loose behavior, or disobedient. (7) For an overseer must be blameless, as a steward of God, not self-willed, not full of passion, not given to wine, not quarrelsome, not greedy for ill gain; (8) but hospitable, a lover of good, discreet, just, holy, temperate, (9) holding fast the faithful Word according to the doctrine, that he may be able, by sound doctrine, both to exhort and to convict the gainsayers.
Verse 6 again says blameless and then husband of one wife. Could a man be blameless if he has been divorced and remarried. Then again in verse 7 it says it again blameless as a steward of God.
Im sure there will be people who disagree with me but these verses mean first and foremost A MAN not a woman A MAN and one that is married to the woman whom he married before God and made a life commitment before GOD. Any other woman besides the woman whom he married origianlly would disquailify him in my eyes.
