Oklahoma Supreme Court has ruled that the approval by a state board of what will be America’s first public funded religious school was unconstitutional. It must be reversed.

Why it matters: Christian nationalists are challenging the long-held doctrine in the United States of separation between church and state, and they want public funding for religions in schools. This is happening amid a super-majority of conservatives on the U.S. Supreme Court.

Oklahoma’s High Court ruled that the Statewide Virtual Charter School Board voted 3-2 last year to approve St. Isidore Virtual Charter School, which violates the Oklahoma and U.S. Constitutions.

The online public charter schools would have been available to all students K-12 in the state, with the goal of evangelizing students to the Catholic faith.

The Catholic Archdiocese of Oklahoma has submitted the application for this school.

Zoom in: According to Oklahoma law, charter schools are public schools. The court ruled that charter schools must not be sectarian.

“However St. Isidore, while being sponsored by the state, will evangelize Catholicism as part of the school curriculum.”

The establishment of a charter school by this state violates Oklahoma Statutes, Oklahoma Constitution and Establishment Clause.

The state of the case: This case has attracted national attention because conservatives and supporters of the school felt that recent Supreme Court rulings showed the court to be open to the idea of public money going to religious institutions.

The announcement came in the wake of a Louisiana law that requires classrooms to display the Ten Commandments.

These cases have brought Christian nationalism to the forefront of American politics.

The intrigue of Oklahoma GOP Gov. Kevin Stitt, State Superintendent Ryan Walters and others supported the approval by the state board of the school. They said that it was a good example of religious liberty.

The school has also received support from conservative legal organizations such as Alliance Defending Freedom.

Oklahoma Attorney General Gentner drummond filed a lawsuit and claimed that the school violated state and federal laws.

According to the AP, a group of parents, religious leaders, and a nonprofit public education organization also filed a lawsuit in order to stop the opening of the school.

What they are saying: “Today’s ruling is disappointing for hundreds of potential students and their parents from all over Oklahoma,” Archbishop Paul Coakley of the Archdiocese of Oklahoma City and Bishop David Konderla of the Diocese of Tulsa said in a joint statement.

We will examine all legal options, and we remain firm in our belief that Saint Isidore is a valuable resource for students regardless of their socioeconomic status, race, or religious background.

Christian nationalism aims to create a country based on the dominance of white American Christianity in all aspects of American life.

Many Christians believe that U.S. law should be based upon Christian values and that God has commanded Christians to exert dominion in all areas of American culture.

The evangelical and conservative Catholic movement and its supporters have allied themselves with Donald Trump, the Republican Party.
