I spoke with another "informed Christian" who stated as fact that since Jesus never spoke out against polygamy or gay marraige, it shows he had no problem with either. Jesus also never spoke out against beating your wife or selling your children into slavery either, so I guess....
Just as an aside, Jesus did speak about polygamy and homosexual marriage as these verses show.
Matt 19:4 But answering, He said to them, Have you not read that He who created
them from the beginning "created them male and female"?
Gen. 1:27
Matt 19:5 And He said, "For this reason a man shall leave father and mother, and shall be joined to his wife, and the two shall become one flesh."
Gen. 2:24
Mark 10:6 But from the beginning of creation "God made them male and female."
Gen. 1:27
Mark 10:7 "Because of this, a man shall leave his father and mother and shall be joined to his wife,
Mark 10:8 and the two shall be one flesh;" so that they no longer are two, but one flesh.
Gen. 2:24
Mark 10:9 Therefore, what God yoked together, let not man put apart.
Jesus said what he said by not saying it. The marriage bond between a man and a women was the only one that Jesus recognised. If there were others, he would have said so. The fact that he didn't meant that he did not accept other forms of marriage.
No different to me saying "If you finish this by Friday, I will give you a bonus." I didn't say "if you don't finish it by Friday, I won't give you a bonus" but I did say it by what I did say if you get my drift.
In addition Jesus said that what God yoked together no one was to break up, again implying that the male/female marriage relationship is the only one approved by God.
