A group of military chaplains is calling for a senior Army chaplain to be disciplined for sharing a book from an evangelical pastor on his military email.

The Military Religious Freedom Foundation, a nonprofit organization with a mission statement supporting a strict separation of church and state in the U.S. military, wrote a letter on Wednesday to Defense Secretary Mark Esper, asking that Col. Moon H. Kim, a senior chaplain, be punished for sharing evangelical pastor John Piper’s latest e-book, Coronavirus and Christ.
