Former President Donald Trump is officially selling a patriotic copy of the Christian Bible themed to Lee Greenwood’s famous song, “God Bless the USA.”

“Happy Holy Week!” Trump announced on social media Tuesday, during the most solemn period of the Christian calendar, the last week of the Lenten season marking the suffering and death of Jesus. “As we lead into Good Friday and Easter, I encourage you to get a copy of the God Bless The USA Bible.”

The concept of a Bible covered in the American flag, as well as a former president’s endorsement of a text Christians consider to be sacred, has raised concern among religious circles. It’s also raised questions about Trump’s motivations, as the former president finds himself in the middle of several expensive legal battles.
