Perhaps you have seen, read, or heard about the Newsweek article that argues that the Bible should not be used to restrict marriage to one man and one woman. The article (it is really more like and editorial because it states opinion and not the result of real research) is one more step in the attempt to get us to step away from Biblical authority.
It is interesting that Religion Editor Lisa Miller quotes several liberal (not politically but theologically . . . theological liberals tend to water down the authority of Scripture and diminish the nature of Christ) scholars but no Bible-believing scholars. In fact, when she was invited to be interviewed on the Laura Ingram show along with Dr. Albert Mohler (President of Southern Baptist Seminary), Miller said she would not come to the interview if Mohler was included! One wonders if this indicates that Miller knew she was distorting what the Bible says.
I encourage you to go to Dr. Mohler's site http://www.albertmohler.com/ and scroll down his blog postings to the one that says "Turning the Bible on its Head -- Newsweek Goes for Gay Marriage". It is an enlightening Biblical response to the Newsweek editorial.
Christians believe homosexuality is sin. Christians do not hate homosexuals. Many Christians understand the desire homosexuals have for civil unions. We understand the "benefits" stuff. However, the idea of special rights for homosexuals . . . giving them a privileged and protected status in society crosses a line. The desire to water down and diminish the Christians view of marriage also crosses the line.
The Homosexual agenda is promoted everywhere. You cannot watch a television program without some kind of gay cast member. The strategy is to make this so commonplace that we will consider it to be normal and simply another lifestyle choice. As this happens our commitment to Biblical truth will give way to political correctness.
Homosexual Marriage may become commonplace. But the fact is that lying is commonplace, infidelity is commonplace, cheating is commonplace, materialistic indulgence is commonplace. Society has accepted and even promoted some of these things. Even if laws were enacted to make these things legal . . . they would still be wrong.
