"Duck Dynasty" star Alan Robertson voiced strong opinions regarding the separation of church and state in a recent interview.

Robertson said that the founding fathers intended for the Bible to be used as a guide when enacting laws, and that biblical principles should be taught in schools.

"I think it's a little disingenuous, some of the reasons why God has been exorcised out of the public square," the eldest Robertson brother told CNS News. "Supposedly, it's been because that's what the founders intended. But all you have to do is go back and look at what was practised and know that's not true at all."

References to God appear in the Declaration of Independence and on US currency, but phrases such as "In God We Trust" and "one nation, under God" are increasingly the subject of freedom of religion lawsuits. Robertson said that the country was designed to be centred on God.

"If you read some of the founders' thoughts on it, their idea was that government and what we're trying to enact in laws will not work unless people are also understanding the Bible and what God says is right and wrong," he explained.

"Several have been quoted, our founders said it won't work, because if people lose the connection to that [God and Bible], why would they care about the laws? In other words, the people can't be rightly governed without some understanding of God's truth and His word."

The ordained minister went on to say that the Bible should be taught in school – particularly the story of Creation.

"To put evolution there, which is a theory by the way, can be taught as the ultimate truth, then you can't look at any other possibility? What kind of discipline is that in terms of education?" he asked. "If we went that route, we'd have never taught some of the things now we know to be true that 50 years ago we didn't even know about."

Instead of excluding religion from schools, Robertson said that students should learn about all faiths.

"Now, I understand the modern argument of, 'Well, what about other religions?' What about this — teach about all of it," he said. "I believe the Bible will always come out as the standard it should be. But all these things should be talked about instead of just shunned. In the public education awareness, it's almost like it almost doesn't exist."
