Texas Gov. Greg Abbott on June 20 signed a bill into law that would require all public school classrooms in his state to display the biblical Ten Commandments.

The law, which goes into effect on Sept. 1, requires classrooms to display a poster or framed English translation of the commandments that is at least 16-by-20 inches and is able to be read from anywhere in the classroom.

Texas has more than 5.5 million students throughout its more than 9,000 public schools.

Supporters of the Texas legislation say the Ten Commandments are a key part of the foundation of the United States’ judicial and educational systems and should be displayed.

“The focus of this bill is to look at what is historically important to our nation educationally and judicially,” said Texas state Rep. Candy Noble, a Republican and co-sponsor of the bill, after it passed the House.

Opponents, including some Christian and other faith leaders, say the Ten Commandments and prayer measures infringe on others’ religious freedom.

Louisiana Attorney General Liz Murrill has said her office is prepared to take the matter all the way to the U.S. Supreme Court.

In that 5–4 ruling in 1980, the Supreme Court held that a Kentucky statute mandating the posting of the Ten Commandments in public school classrooms was unconstitutional because it lacked a secular legislative purpose, violating the establishment clause of the First Amendment.
