Josie, with all the respect in the world, I would like to point out that Christians are being hypocrites when they "put little emphasis on the Old Testament." Fact is, without the Old Testament, Christianity and the New Testament make absolutely no sense!
And I would also point out that the "condemnation of homosexuality" is not confined 100% to the Old Testament. Paul has at least 4 instance of what undoubtedly is condemnation of homosexual activity.
In fact, if the words of Jesus are important to Christianity (not sure they are) then all the laws of the Old Testament should be emphasized a great deal by Christianity.
