The book of Genesis gives us the basis for marriage.
You see, the truth is this: we may speak of “thousands of years of Judeo-Christian ethics” as the basis for our need to keep the definition of marriage as the union of a man and a woman in matrimony. The problem is this, however: those who want to redefine marriage have no allegiance to Judeo-Christian ethics. Their ethic is a post-modern relativism, so that truly has no bearing on them in their minds.
Too many Christians have walked away from the truth of the first three chapters of Genesis. They have sought to accommodate evolution in different ways. Having done so they have effectively deleted the force and relevance of the morality of Genesis 1-3. Why? Because if the Creation account is not true, neither is the institution of marriage that the Creator gave to His human creatures.
It is indeed as simple as that.
This culture war did not start with homosexuals wanting to be married. It started with modernists who want to compromise Scripture in a desire to accommodate pseudo-scientific fallacies such as evolution. Thus we have the day age theory, theistic evolution, and a smorgasbord of other theories. In the end, we should accept the historical account that was given to us by the ONE Who MADE all of this.
Oh, I know, I (and all others who believe in Biblical Creation) will be viewed as ignorant country bumpkins, and possibly even dangerous people. The true danger lies, however, in the fact that, if we deny, reject, or change Genesis 1-3, we are loosed from our mooring and are drifting in a sea of social change without any guide.
Yes, the real culture war began back in the nineteenth century when ministers capitulated to Darwinism. It blossomed in Germany in their universities and seminaries and ultimately led to the Holocaust. If only there had been enough Bible-believing Christians in Germany in the 1930’s the Holocaust may not have happened. Immorality and violence blossom in the absence of Biblical morality and ethics, though. As Germany went, so goes the USA, it seems.
How sad that we refuse to learn from history.
