The Supreme Court’s conservative majority on Wednesday seemed open to backing the creation of a Catholic charter school in Oklahoma, a decision that would expand the availability of taxpayer money for religious education in school systems across the nation.

The Catholic Church in Oklahoma wants taxpayers to pay for an online charter school that “is faithful to the teachings of Jesus Christ.”

The Supreme Court heard arguments over whether taxpayer dollars may be used to directly fund a proposed Catholic charter school in Oklahoma. The case could redraw the line between church and state.
