It is a misconception of Jesus' teachings to say that he invalidated the Mosaic law with a message of "it's all about love". Notice in the Sermon on the Mount for example how he is constantly going one level more conservative than the Mosaic law would allow, condemning not just immoral actions but immoral thoughts as well!Here on the issue of homosexuality you believe Moses, Jesus and Paul say 3 different things. And yet Jesus clearly states that he didn't come to change the Mosaic law in any way!

Martin Luther took that last verse to mean that Jesus is not merely giving a list of do's and don'ts, but rather setting an impossibly high standard for anyone but God to meet. Regardless, you have to either understand Jesus to mean that he's not contradicting Moses, or take Jesus to be a liar. There aren't many reasonable options in between.
