Pope Francis reaffirms bishops must get Vatican approval to allow Latin Mass
Pope Francis has unequivocally confirmed that bishops must obtain authorization from the Holy See before granting permission to celebrate the pre-Vatican II Mass in parish churches and before allowing priests ordained after July 16, 2021, to use the 1962 Roman Missal. The latest instruction also makes clear that bishops cannot take the law into their own hands and interpret in a different way the restrictions on the Latin Mass issued by the pope in 2021.
