As far as Answers in Genesis founder Ken Ham is concerned, it is wrong for any pastor to support same-sex marriages. The Creationist says people who truly understand the Bible will definitely say that marriage should only be between men and women.

"News today that a high profile pastor in London is going to issue same-sex marriage licences—a flagrant disobedience of God's Word!" he writes on his Facebook page without naming the pastor. "If people believe the history in Genesis 1 [and] 2, then there's no option but to understand that marriage is between one man and one woman."

Ham shares several Bible verses that reveal the origin of marriage and God's purpose for it. Genesis 2:23 reads: "This is now bone of my bones and flesh of my flesh; she shall be called woman, because she was taken out of man."

Genesis 1:27 to 28 reads: "Male and female He created them. Then God blessed them, and God said to them, 'Be fruitful and multiply.'"

"One of the primary importances of marriage is to produce Godly offspring (Malachi 2:15). Remember, only male and female can produce offspring," reminds Ham.

Meanwhile, there are secularists in Kentucky called the Tri-State Freethinkers who are trying to oppose Ham's Ark Encounter project, which will open on July 7. The Ark Encounter is a life-sized replica of Noah's Ark, replete with animal displays and an educational tour on how Noah and his family survived the great flood.

The Tri-State Freethinkers have put up several billboards that poke fun of the Ark Encounter. "Genocide & Incest Park," their billboard reads. "Celebrating 2000 Years of Myths."

Ham is enraged by the group's alleged "free exercise of religion," criticising them for not wanting Christians to have their own freedoms.

"Their disparaging billboard campaign reveals their true motives—they're afraid of Christians proclaiming truth of Bible. And though they have no absolute basis for morality, they inconsistently make moral judgments against the only absolute authority—God!" says Ham.
