Christian conservative James Dobson claims gay marriage will be “the death knell of religious liberty in America.”

Dobson, the founder of Focus on the Family, which he led until 2003, is the host of Family Talk with Dr. James Dobson, which is broadcast on over 300 radio stations nationwide.

Last month, he predicted civil war if the Supreme Court strikes down state bans on gay marriage.

During a speech at the annual National Day of Prayer, which is overseen by his wife Shirley Dobson, Dobson warned of dire implication for the United States should the Supreme Court strike down the bans.

Allowing gay couples to marry in all 50 states would undermine, compromise and weaken the family, he stated.

This decision, like Roe v. Wade, is going to “divide us further,” Dobson warned.

“How are parents to teach their small children what the Bible has to say about this when they must put them on a school bus and go to school and be taught the opposite by those in authority over them,” he wondered.

“It has implications for the school. Textbooks are going to have to be re-written and re-illustrated to comply with the law,” he added. “It reaches every corner, every dimension of society. We are talking about the death knell of religious liberty in America.”
