Phil Robertson has offered up another of his enlightened thoughts.
As part of his sermon at White's Ferry Road Church in West Monroe in Los Angeles, he preached to a congregation how best to avoid sexually transmitted diseases.
The trick, he says, is to only have sex within marriage.
"Biblically correct sex is safe," said Robertson. "It's safe. You're not going to get chlamydia, gonorrhoea, syphilis, AIDS."
"If a man marries a woman, and neither of you have it, and you keep your sex between the two of you, you're not going to get ever sexually transmitted diseases."
He has little time for those who have sex outside of marriage and said that the spreading of STIs in the US was because many people "follow liberal orthodox opinion" and procreate with "anything and anybody".
"The Bible said one man, one woman: that's what [God] made to begin with," he continued. "For this reason, we have a male and a female. For that reason, those two can come together and be married. And when they marry, what God has joined together, let man not separate."
Robertson, 68, has been married to his wife, Marsha Kay Robertson, for 49 years.
The Duck Dynasty personality is known for his controversial views; in December 2013, he sparked outrage for his homophobic remarks made in GQ magazine, in which he claimed that homosexuality was one step away from bestiality.
GLAAD, the Gay and Lesbian Alliance Against Defamation, described Robertson’s GQ comments as "one of the vilest and most extreme statements uttered against LGBT people in a mainstream publication".
"It seems like, to me, a vagina - as a man - would be more desirable than a man's anus," Robertson said in the magazine.
"That's just me. I'm just thinking: There's more there! She's got more to offer. I mean, come on, dudes! You know what I'm saying? But hey, sin: It's not logical, my man. It's just not logical."
TV channel A&E, which airs Duck Dynasty, released a statement shortly afterwards, describing how they were "extremely disappointed" with Robertson’s opinion and explained that his "personal views in no way reflect those of A+E Networks, who have always been strong supporters and champions of the LGBT community."Reuse content
