For the second time in less than a year, a Mississippi school district has run afoul of a watchdog group which says the district is violating the U.S. Constitution by disciplining a 1st-grader for saying “Jesus Christ” after he dropped a handful of Legos while cleaning up.

The Freedom From Religion Foundation (FFRF) notified Elizabeth Lee Maron, attorney for the DeSoto County (Miss.) School District in a Jan. 19 letter that the practice of imposing discipline for Christian blasphemy was a violation of the establishment and free speech clauses of the Constitution.

The 7-year-old’s mother posted a photo of the Parent Notice of Disciplinary Incident she received on Jan. 4. Of the incident, the teacher wrote: “He said ‘Jesus Christ’ when he dropped the Legos he was cleaning up from recess.’”

The teacher tagged “unacceptable language” as the reason for the disciplinary notice.

The notice also indicated the teacher had called the boy’s mother regarding the incident and had a “conference with the student.”

A spokesperson for the school district said in a statement to Fox News a student would not be reprimanded for simply saying Jesus Christ, but that “it is possible a student could be corrected for a disrespectful use of Jesus Christ’s name.”

“It is well settled that public schools may not show favoritism towards, nor encourage or coerce belief in any religion,” FFRF Staff Attorney Chris Line wrote to Maron. “Thus, a school district cannot mandate, encourage, or coerce students into complying with religious rules, such as prohibitions on blasphemy.”

The FFRF noted the prohibition against “taking the Lord’s name in vain” comes from the Ten Commandments. The U.S. Supreme Court has ruled on multiple occasions the Ten Commandments are clearly religious in nature and thus should not be found in a public school.

“The child who was reprimanded is attending a secular public school, not a religious institution,” saud FFRF co-president Annie Laurie Gaylor.

“This was an egregious and traumatizing violation of the child’s rights. The district must adopt clear policies ensuring such overreach will never recur and publicly apologize to the child and his family.”

This isn’t the first time the DeSoto district has been accused of violating Constitutional protections.

Last year, complaints to the FFRF said the district was conducting “scheduled prayer” prior to school events.

Requests for comment from DeSoto school officials went unanswered.
