Everyone has a worldview that dictates how they view reality. That view of reality contains ideas that have real consequences, and those ideas are championed through truth claims (E.g., Same-Sex marriage ought to be tolerated) that seep into the culture.
Unfortunately, when worldview truth claims are not tested through logic, but embraced through emotions, reality becomes twisted. This results in calling what’s bad good, what’s wrong right, what’s false true, and what’s unrighteous righteous. For professing Christians who support “Same-Sex-Marriage” I ask on what grounds? Biblically it’s a twisted view of reality and part of the catalogue of sins for why God’s wrath has been unleashed (Rom.1:18-32).
Now that same-sex-marriage is legal does it make it moral? On what grounds is it moral, what’s the basis for it? Whatever your answer friend, you’ll use words and thoughts to convey your view. When this happens you and I come into the use of logic (Click for Primer Chart on Logic) whether done well or poorly. Douglas Groothuis talks about this issue of logic and applies it to the same-sex-marriage decision.
“He argues that If same-sex marriage is moral, then any consensual sexual arrangement (involving marriage or not) is moral. Same-sex marriage is moral. Therefore: consensual polyamory, incest, pedophilia, and bestiality are moral. But (3) is absurd, since these acts are immoral. Therefore, it is false that same-sex marriage is moral; it is immoral.”
Part of the way Christians are to love God is with the mind, making proper distinctions and using logic well is one way we follow Jesus friends. When we don’t use logic well, we fail to properly reflect our glorious God and hinder the cause of Christ rather than advance it. Therefore, how well are you thinking friend?
