The Supreme Court agreed to hear a bid by Oklahoma officials to approve the nation’s first publicly funded religious charter school, setting up the possibility for the barrier between church and state to be weakened.

The court, which has a 6-3 conservative majority that consistently backs religious claims, will hear a dispute over the proposed St. Isidore of Seville Catholic Virtual School, which would serve students online throughout the state while maintaining its remit to promote the Catholic faith.
