An evangelical pastor from Atlanta announced Thursday that he would not give the benediction at President Obama's swearing-in ceremony after a sermon he gave on homosexuality in the mid-1990s resurfaced earlier this week.

In that sermon, the Rev. Louie Giglio called for Christians to "firmly respond to the aggressive agenda" of some in the gay community and warns that widespread gay marriage  "would run the risk of absolutely undermining the whole order of our society."

In a statement, Giglio said that his participation "will be dwarfed by those seeking to make their agenda the focal point of the inauguration."
