What was once allowed---such as brothers and sisters marrying---came a time when God said no more.
Act_17:30 And the times of this ignorance God winked at; but now commandeth all men every where to repent:
NT rules are one wife. And it wasn't just for bishops and deacons as all church elders came from the laity.
When the Apostles during the Council of Jerusalem (Acts 15) lay down the rules and morals for Gentile believers, their framework of reference is Mosaic Law. So when 'abstaining from sexual morality' was prescribed in Acts 15: v20 + v29, the sexual morals of the OT clearly are referred to and applied to Gentile believers as well - they simply had no other valid framework available. Neither Jesus or John the Baptist banned or even criticised Polygamy; to the contrary - Jesus emphasises the Law to the smallest detail had to be taught and done (Matthew 5: v19).
Using Paul's requirement list for Elders and Deacons using the ambiguous phrase 'one woman man' as the only source then for a supposed NT ban on Polygamy seems rather questionable to me; especially given the fact we're not exactly sure what Paul meant by that, and the sharp contrast of such a supposed NT rule with the OT message. A variety of interpretations have been given over time for the phrase:
- a man with exactly one woman/wife
- a man with a maximum of one woman/wife (at any time, or over his lifetime)
- a man who has not been divorced
- a man who never has remarried after his 1st wife died or left
- a man who is faithful/loyal to his 1st woman/wife his marriage (not sending her away unjustly)
A literal reading (the first option: exactly one woman/wife) is impossible because that would disqualify Paul himself from Eldership - saintly singles also qualify we presume. Btw it should be noted the word for 'one' (Greek: 'mia') sometimes can also be translated 'first' in some NT verses.
I would urge any reader to read William Luck's careful treatment of this famous phrase (see
14. On the Morality of Biblical Polygyny | Bible.org); and then ask himself the question whether Paul's eligibility statement can be taken as overturning OT law, and declaring sin what God clearly allowed before (that's a rhetorical question
).
The entire nation of Israel built up from the sons from Jacob's four wives; God's gift of King Saul's women (plural) to David (2 Samuel 12: v7-8), God portraying himself as being married to two sisters (Jeremiah 3: v6-10, 31: v31-32; Ezekiel 23), the righteous priest Jehoiada picking two wives for the righteous King Joash (2 Chronicles 24: v3). The good King Abijah being commended of his blessing with 14 wives (2 Chronicles 13: v21). The list of instances where multiple wives and a large offspring were seen as a blessing from God is impressive. To me it seems highly unlikely that such blessings, all of a sudden, in NT times would be declared a sin just because of Paul's eligibility list.
The pattern in Acts is that we see Gentile believers have
less laws to obey than the Jewish believers, not more. A sudden new ban on polygamy would counter that. To think that ban was introduced by the Apostles to me comes across as a light-founded assumption. As Paul argues that sin is defined by the Law (Romans 7: v7), for Paul it would not have made sense then to suddenly declare polygamy to be a sin while the Law did not.
For the interested reader I would encourage to also read the excellent historical overview and treatise on Biblical Polygamy from a Jewish perspective by Blaine Robison:

Personally speaking, I think Paul's eligibility list may have one of three possible meanings:
- a maximum of one woman/wife for an Elder/deacon (as that may leave more time for ministry), or
- faithfulness/loyalty to his first wife
- disqualifying womanizers (Prof. William Luck's preferred interpretation); as the target audience for the relevant letters was predominantly Roman or Greek and not Jewish - Paul's wording makes sense for a nominal monogamous (Roman, Greek) audience; not for a Jewish (and therefore partially polygamous) audience.
