A mother who was told she can no longer pray on the steps of her children’s high school in New Hampshire has returned, but is praying in silence. Lizarda Urena, of Concord, had been praying near Concord High School for the protection of the students. In February, she started reciting Bible passages on the school’s steps for about 15 minutes daily after police responded to a report of bullets found in a toilet. After the district got questions and complaints, the principal told her she could not pray on campus. The Alliance Defending Freedom, a conservative Christian group that advocates for religious rights, is providing legal services to Urena.
