"Is there such a thing as an absolute right or wrong?"

Right or wrong and the absolutes are a hard issue to be discussed for most people, especially Christians. Some Christians have been using the bible as a manual for the right or wrong absolute. It is not that Christians are extremists, but they feel the need to defend what is right and separate from what is wrong. The problem with this is that a wall was created in between sacred and secular, Christians and non-Christians.
Let’s use gay marriage as an example. Christians have been pressing for amendments, bans, and respect for the institution of marriage. The bible says that homosexuality is wrong. Homosexuals are going to hell. God hates fags. We hear that all the time. The point here is not whether homosexuality is right or wrong, but how we approach the issue.
On the other side, our culture is based in ourselves. We see the truth as a personal opinion. We've been told that no one can say which religion or set of morals are true, therefore we do what we want; we are entitled to make our own decisions.
Christian intransigence has been one of Satan’s biggest tools. He loves when we go out there calling everybody rotten and corrupt. He takes delight when a group of Christians raise banners against Homosexuality, gay marriage, democrats and etc. Sometimes it seems like that Christians are, in their zeal to God's affairs, Satan’s biggest helpers.
Paul writes that if you are not mature enough to eat certain type of food, don’t eat; but also do not pass judgment over someone that eats certain type of food. Where is the absolute right or wrong there? Jesus infuriated the teachers of the Law by picking up fruits to eat on a Sabbath. Where is the absolute right or wrong there? It was wrong for a Jew to travel from south to north through Samaria, but Jesus did it anyway. Where is the absolute right or wrong there? On that same trip He spent sometime alone talking to a strange woman, and she gave her life to Him then led half of her city to Christ as well. Where is the absolute right or wrong there?
Is it right to be a homosexual? I cannot say it is. The bible clearly condemns it. Does that give me the right to pass judgment over it? Does God hate the person because of the sin? Some might say: Jesus called others hypocrites, liars, sinners and etc; why cant I do the same? To the best of my knowledge, Christ was blameless and sinless. He had the authority to tell anything to anyone, due to His pureness. What about us? We are all fallen, corrupt, selfish and dirty; none of us deserve forgiveness.
Morals alone cannot fix anything. Instead of fighting against gay marriage, we should preach the gospel, because the only thing that can set a sinner free from any kind of sin is Jesus Christ. He is the only absolute right. Now, what do we do with the wrong?
