Do you think its morally ok from a Christian standpoint to date 2 females at once being the both are ok with it of course. Would such a relationship be frowned upon in a Church.
To date? Confusing.
Obviously the Bible teaches that you shouldn't have sex with any woman you are not married to. Fornication is sin, and the Bible specifically says people who practice that will not go to Heaven.
As for marrying two women, um...
Ideally it is one man and one woman. That is the ideal.
There are hundreds of verses that talk about people in the Bible marrying multiple wives. So I find it difficult to say that it is morally wrong to marry multiple wives.
You will no doubt find dozens of people here saying it is morally wrong. It certainly isn't the Ideal laid out in scripture.
But how do you explain Jacob, or Elkanah who was the father of Samuel, or David the king, or the list goes on and on.
How many hundreds of people in the Bible, who were great leaders and spiritual people approved by G-d, and yet all have multiple wives, do you need before you conclude that having more than one wife isn't all the bad?
David and Bathsheba, is a perfect example. G-d never once complained, or punished David for having Bathsheba for a wife, when he was already married 3 times. He complained, because he killed her husband, and slept with her when she was already married. Then after being punished for those evils, he had no problem with David and Bathsheba having kids.
So I logically can't say that it is morally wrong to marry more than one woman. If it is wrong, then most of the patriarchs of the past, that we have as a basis for our faith, were all evil sinners.
I still think that the absolute best you can hope for is, one man and one woman. It works out best that way.
While G-d did not punish those people for polygamy, most of those relationships in the Bible, had problems. So the ideal remains, one man, one woman.
All that said.....
I don't know where you are from, but here in the US, you can't legally marry multiple wives.
The Bible says you should follow the laws of the land.
So since you can't marry more than one, then being with one you are not married to makes you a fornicator, and that is expressly prohibited in Christian faith. The Bible makes it clear, you can't be screwing women you are not married to. If you do, then you will reap judgement, not reward.
It's that simple.
