Controversy over the selection of Rev. Louie Giglio to deliver the benediction at President Obama’s inauguration later this month began growing on Wednesday after Think Progress revealed he had delivered an anti-gay sermon in the 1990s. In the sermon, Giglio not only advocated for reparative therapy, he also said Christians must “firmly respond to the aggressive agenda of not all, but of many in the homosexual community” in order to prevent “the homosexual lifestyle” from becoming “accepted as a norm in our society.” He also said "it is very clear" that "homosexuality is sin."
