Why Christians Have Not Been Successful in the Debate against "Same-Sex Marriage"

An excerpt from Mr. William O. Einwechter's 2006 article found here:

"Evangelical Christians are not doing very well in the debate over “same-sex marriage” and other issues in regard to “gay rights.” Why is this? Let us consider two factors.

First, Evangelicals do not appeal to Scripture in the public debate, but base their arguments on reason and “natural law.” By so doing they surrender the only real authority and power they have (Isa. 8:10; Eph. 6:17; Heb. 4:12) and are forced to stand on the same ground as their opponents. Not only does this method disarm the Christian, it is also disingenuous. The leading reason why Christians reject homosexual behavior is because the Bible teaches them to do so. In refusing to stand up and say this, especially since their opponents know that their chief objection is based on the Bible, they appear to be dishonest and ashamed of their faith. It is much better to be bold and forthright in defending biblical morality by using the Bible! Even if their enemies reject their arguments, Christians cannot help but gain a measure of respect for their honesty and courage.

Second, Christians seem blind to the hypocrisy of treating homosexual conduct so seriously and adultery and divorce so lightly. Evangelicals cry out that they must defend “traditional marriage” against the danger of “gay marriage.” But the greatest threat to traditional marriage is not from without but from within; from the rampant adultery and divorce that is found in heterosexual marriages. Churches preach against “gay marriage” (and rightly so), but tolerate adultery, divorce, and adulterous remarriage within their own memberships. The divorce rate among Christians is a disgrace. The church is so morally compromised by adultery and sexual sin (e.g., addiction to pornography and fornication) among its heterosexuals that it has lost its power to confront the plague of homosexuality."
