The FBI says it's investigating a Washington state Republican who distributed a manifesto calling for "war" against enemies of the Christian religion.

The document, a four-page explanation of how to establish Christian law through armed struggle, calls for the end of same-sex marriage, abortion, and the death of all non-Christian males in the U.S. if religious law is not upheld.

“If they do not yield — kill all males," the document reads.

FBI representatives told local NBC affiliate KHQ 6 that it is investigating the document, which was reported to to the bureau by Spokane County Sheriff Ozzie Knezovich, who told the news station that he felt the post was dangerous.

“The document Mr. Shea wrote is not a Sunday school project or an academic study,” Knezovich added to the Washington Spokesman-Review. “It is a ‘how to’ manual consistent with the ideology and operating philosophy of the Christian Identity/Aryan Nations movement and the Redoubt movement of the 1990s.”

Shea defended the document in a Facebook Live post this week, calling it part of a "sermon" and taken out of context as a call for violence.

“First of all, it was a summary of a series of sermons on biblical war in the Old Testament as part of a larger discussion on the history of warfare,” he said on Wednesday.

“This document, in and of itself, was not a secret. I’ve actually talked about portions of this document publicly.”

Shea, who is running for reelection, has lost at least one campaign donor over the controversy. A spokeswoman for the Northwest Credit Union Association told Spokane Public Radio that the group had requested the return of a $1,000 donation to Shea's campaign.

“His beliefs do not reflect the views and values of our organization, member credit unions or customers,” the spokeswoman said.
