After the ambush, he leaves the barn, it’s dark outside and a car is waiting for him.
He gets inside the vehicle and we see another priest - who is actually dressed like a priest - sitting within.
This is where the audience learns - from the ensuing conversation - that the shooter is a priest.
Later we see him walking in a heavily adorned palace, where other priests greet him as a bishop.
