Politicians of both parties who heretofore have defined themselves as Christians are embracing a heterodox view of marriage. By doing so, they’re implying that same-sex marriage is compatible with Christianity. Yet here is Jesus’ definitive word on marriage:
Have you not read that he who created them from the beginning made them male and female, and said, ‘Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh?’ So they are no longer two but one flesh. What therefore God has joined together, let no man separate (Matthew 19:4-6 ESV).
According to Jesus, marriage is coeval with God’s creation of the two sexes. Since his definition is entirely based on the account in Genesis, it’s impossible to make same-sex marriage conform to it. You can reject his definition, but then why call yourself a Christian?
We’re entering an era where it’s no longer necessary for an American candidate for president to be Christian. In fact, soon it might even politically benefit a candidate to declare that he or she is something other than a follower of Christ. Given this change, it might be better for everyone involved if politicians who support same-sex marriage stopped confusing people by calling themselves Christian. Consider calling yourself a Unitarian instead.
