Same Sex Marriage
The Old Testament goes far in speaking against homosexuality, and provides extreme punishment for those actions. The New Testament (The New Covenant) speaks more softly about the issues with Jesus not speaking one word towards them but does, through the Apostle Paul infused with the Holy Spirit, tell us to "avoid sexual immorality, that each of you should learn to control his own body in a way that is holy and honorable, not in passionate lust like the heathen who do not know God; ... The Lord will punish men for all such sins, ... for God did not call us to be impure, but to live a holy life." (1 Thessalonians 4: 3-7)
In Romans 1: 18-32 Paul speaks, almost shouts, about God's wrath against mankind for sexual immorality and unnatural relations. It is very evident that Paul saw these things as horribly against God and sure to invoke God's wrath come judgment day.
In the very beginning of the next chapter however, writing to Christians in Rome and all the world, Paul says this: "You, therefore, have no excuse, you who pass judgment on someone else, for at whatever point you judge the other, you are condemning yourself, because you who pass judgment do the same things."
Jesus, in Matthew 5:27-28, says this: "You have heard that it was said, 'Do not commit adultery.' But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart."
We are all sinners. It is simply a matter of what one's sins are. With Newt Gingrich in an affair while he publicly chastises Bill Clinton for his, who is the greater sinner? Neither. All sin is the same.
In "The Augsburg Confession", a document from 1530 written by Philip Melanchthon that is considered early papers of the Lutheran Church, the theology of Original Sin is this: "(We) ... teach that since the fall of Adam all men begotten in the natural way are born with sin, that is, without the fear of god, without trust in God, and with concupiscence; (Saving some time: "concupiscence" means a powerful feeling of physical desire, or lust) and that this disease, or vice of origin, is truly sin..."
All Christians are sinners. All sin is the same. Don’t use another’s sin as the basis for recrimination, especially in the public eye.
Gay marriage is seen as a church issue only because the church is the place many get married. A church, as a private institution, may choose to marry gays, or may choose not to. Differing churches have differing acceptance of this issue. Gay marriage is but one of many differences of interpretation of God’s Word that are the reasons for diverse denominations within the greater church of Christ. If you seek Faith, regardless of your sinful nature, there is a church there for you. Go, be welcomed, and learn the Word. Worth noting - even in a church that allows gay marriage, consider that you will likely need to have a long chat with the pastor about your faith and what it means before they will agree to bring your union before God.
Gay civil union is a different matter entirely. In considering laws for or against civil unions among people of the same sex the ONLY consideration is the Constitution and the other laws of this land. America is a country based upon great personal freedoms, not a theocracy. Those that wish to hold religious beliefs are entitled to do so but, while they hold themselves (or are held as may be appropriate) to God’s Law, there is no basis in American law for forcing God’s Law on those outside their faith.
My sense is that marriage should be handled by churches and civil union should be the governmental responsibility. For those that "believe in the sanctity of marriage", I say do so in your church. You are bound by your faith and that is honorable. Condemning those outside your faith to live by the laws of your faith only pushes them further from any desire to learn of that faith. Giving gays the opportunity to commit, legally and/or before God, brings all the blessings and curses any union that fails about half the time can offer.
If you are against gay marriage, be so on personal grounds, but don’t bring Christ into it unless you are without sin.
