In all the discussions about homosexual “marriage,” one often hears slippery slope arguments and other negative effects that such a radical redefinition of marriage would engender. Even the Christian community tends to approach this issue more from a sociological standpoint than a biblical one. But Christians should be far more concerned about the theological basis for the definition “marriage = 1 man + 1 woman.”
I believe that there are two main reasons why Christians ought to be troubled by attempts from the left to remake society in their own perverted image. First of all, marriage is more than a social construct; it is a creation ordinance, meaning that it is something that God Himself has ordained and pronounced “good.” What God hath joined together, let not man put asunder; and if God has decreed that man is to cleave to his wife and they are to become one flesh, then man has no moral authority to tinker around with that relationship. It may sound trite, but it’s true: God made Adam and Eve, not Adam and Steve. Pretending that homosexual unions are every bit as morally legitimate as (have we really come to the point where it’s necessary to spell it out? heterosexual) marriage is an affront to believers who hold to the authority of Scripture.
Furthermore, as believers we acknowledge the teaching of Scripture that marriage is symbolic of the union between Christ and His church. To pervert the definition of marriage and degrade it to include homosexual unions is therefore mockery and an affront to God as well.
Now, I don’t expect unbelievers to do anything other than live in unbelief and sin; if they insist on mocking God in this and other ways, they will one day give an account for their wickedness. But for self-professing Christians to join in the world’s mockery by winking at homosexuality and going along with homosexual unions is inexcusable. We don’t need to take a five-year hiatus to figure out something when God has clearly spoken in Scripture, and we don’t need to make excuses for people who wallow in their perversions. If we are faithful to Scripture, we will instead call people to repentance and warn them that the unrighteous will not inherit the kingdom of God.
I have no pleasure in the death of the wicked, but that the wicked turn from his way and live. (Ezekiel 33:11)
