I as an baptist, I call those movements as the work of the devil

z(because it keep people from hearing the Gospel of Christ) But yes, some baptist (especially the Ruckman or hyles type of baptists) do not believe in mixed marriage, but most don't know that they already have mixed race in their blood (indians, black, etc.) and just happened to look white. Anyway, most baptists do not believe in mixed religion marriage. If one person is catholic and the other is baptist, it is considered unequally yoke.
2Co 6:14 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
people have been using the bible for their own selfishness for years. They abuse the bible so they can say "SEE HERE, GOD APPROVES OF WHAT I AM DOING", and they are missing the whole point. I think most of the abusive idea of segregation came from the old testament, which is the same as Jewish Torah.
The whole old testament is about Law so we can understand how much of a sinner we are if we tried to obey everything, we are bound to fail. It's to show how holy God is. The new testament is about God's grace. You don't see anything in the new testament about stoning anyone, I don't think. They tried to stone a adultress, but Jesus said who is without sin can cast the first stone. Everyone left because they knew they were not without sin. Jesus is without sin, because he is the Lord, could cast the first stone if he wanted to, but he didn't because he forgave the adultress and told her to sin no more.
The whole point of the bible? well the point is God is the perfect one and we are the messed up ones, and that we can't put ourselves in heaven. God does the saving and put us in heaven..... BUT if you don't want to have anything to do with God and his holiness, you are welcome to walk away from it all. You are welcome to disown him because he can not change from holiness to unholiness for your sake. The problem is, everything was created by God so actually you are walking away from everything that gave you joy. So God have to make a place for people to go to, and the absent of God isn't pleasant, just like the absent of sun isn't. Or the absent of Government laws isn't pleasant so that's why Jails are built for people who doesn't want to have anything to do with the government and it's law. If you submit in his control, and listen to the gospel of Jesus. It is God's ways to show us grace, if we can't understand the suffering, we can't understand how much God loves us and want us to come to him.
