Paul Ryan weighed in Wednesday on the Democrats’ 2012 platform, which makes no reference to “God,” calling the omission “rather peculiar.”

“It’s not in keeping with our founding documents, our founding vision, but I guess you would have to ask the Obama administration why they purged all this language from their platform,” Ryan said on Fox News.

The word God is not mentioned in the U.S. Constitution. The word “Nature’s God” appears once in the Declaration of Independence, alongside mention of the word “Creator.”

The new platform refers to faith, saying it “has always been a central part of the American story.” It also says the US was founded on the principle of religious freedom and the ability of people to worship as they please. It praises the work of faith-based organizations.
