If pologmy was accepted/endorsed in the bible, particularly by Christ Himself, He would not have made these statements:

Quote
Mark 10
2 Some Pharisees came and tested him by asking, "Is it lawful for a man to divorce his wife?"
3 "What did Moses command you?" he replied.
4 They said, "Moses permitted a man to write a certificate of divorce and send her away."
5 "It was because your hearts were hard that Moses wrote you this law," Jesus replied.
6 "But at the beginning of creation God `made them male and female.'
7 `For this reason a man will leave his father and mother and be united to his wife,
8 and the two will become one flesh.' So they are no longer two, but one.
9 Therefore what God has joined together, let man not separate."
10 When they were in the house again, the disciples asked Jesus about this.
11 He answered, "Anyone who divorces his wife and marries another woman commits adultery against her.
12 And if she divorces her husband and marries another man, she commits adultery."


Quote
Matthew 19
3 Some Pharisees came to him to test him. They asked, "Is it lawful for a man to divorce his wife for any and every reason?"
4 "Haven't you read," he replied, "that at the beginning the Creator `made them male and female,'
5 and said, `For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh'?
6 So they are no longer two, but one. Therefore what God has joined together, let man not separate."
7 "Why then," they asked, "did Moses command that a man give his wife a certificate of divorce and send her away?"
8 Jesus replied, "Moses permitted you to divorce your wives because your hearts were hard. But it was not this way from the beginning.
9 I tell you that anyone who divorces his wife, except for marital unfaithfulness, and marries another woman commits adultery."


Quote
Matthew 5
31 "It has been said, `Anyone who divorces his wife must give her a certificate of divorce.'
32 But I tell you that anyone who divorces his wife, except for marital unfaithfulness, causes her to become an adulteress, and anyone who marries the divorced woman commits adultery


Quote
Luke 16
18 "Anyone who divorces his wife and marries another woman commits adultery, and the man who marries a divorced woman commits adultery.


Quote
1 Corinthians 7
10 To the married I give this command (not I, but the Lord): A wife must not separate from her husband.
11 But if she does, she must remain unmarried or else be reconciled to her husband. And a husband must not divorce his wife.
12 To the rest I say this (I, not the Lord): If any brother has a wife who is not a believer and she is willing to live with him, he must not divorce her.
13 And if a woman has a husband who is not a believer and he is willing to live with her, she must not divorce him.


Quote
Moses' instruction to Solomon generations in advance:
Deuteronomy 17:14-20 is God's warning against the polygamist practices of Solomon. After stating that the king [Solomon] is not to get riches from Egypt, nor to amass silver or gold, Moses says, "He must not take many wives" [Deut 17:17].


Quote
"A deacon must be the husband of but one wife and must manage his children and his household well." [I Timothy 3:12]


Quote
Heb 13:4 Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge.


Quote
Jer 29:23 Because they have committed villany in Israel, and have committed adultery with their neighbours' wives, and have spoken lying words in my name, which I have not commanded them; even I know, and am a witness, saith the LORD


Quote
Jas 4:4 Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God.


Quote
1Co 7:2 Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband.


Quote
Joh 4:17 The woman answered and said, I have no husband. Jesus said unto her, Thou hast well said, I have no husband:
18 For thou hast had five husbands; and he whom thou now hast is not thy husband:


Quote
1 Timothy 3:2: “A bishop, must be blameless, the husband of one wife.”


Quote
Jacob 2:24 - 29: "Behold, David and Solomon truly had many wives and concubines, which thing was abominable before me, saith the Lord. Wherefore, I the Lord God will not suffer that this people shall do like unto them of old. Wherefore, my brethren, hear me, and hearken to the word of the Lord: For there shall not any man among you have save it be one wife; and concubines he shall have none; For I, the Lord God, delight in the chastity of women. And whoredoms are an abomination before me; thus saith the Lord of Hosts. Wherefore, this people shall keep my commandments, saith the Lord of Hosts, or cursed be the land for their sakes."


From the beginning, it was ONE man, for ONE woman and TWO become ONE flesh. Nowhere does God endorse/support pologamy, but instead has condemned such as adultery. We have to remember that certain practises that did indeed occur in the old testament were not pleasing to God (King Solomon is one such example) and Christ told the apostles why such things went on was because OF THE HARDNESS OF YOUR HEARTS!

Pologomy is nothing more than MULTIPLE ADULTERY! Jesus does not recognise even divorce, unless there the marriage was a sham or there are such grounds for divorce that Chris recognises. The ONLY allowance for re-marriage is if your spouse has died, or again if the marriage is not valid. Outside of that, as far as God is concerned, the person is still married regardless of them claiming "divorce". Those who are still married who "marry" another, COMMIT ADULTERY if their divorce is not recognised by God.

I'll focus on this quote here just in case anybody missed it:

Quote
Matthew 19:9
Now I say this to you; anyone who divorces his wife - I am not speaking of an illicit marriage - and marries another, is guilty of ADULTERY.


Quote
Ex 20:14
[b]- THY SHALT NOT COMMIT ADULTERY [/b]


Couldn't be more clearer than all of this!
