Theophylact of Ohrid — as excerpted in the Catena Aurea on Luke 17:11-19

“They do not merely supplicate or entreat Him as if He were a man, but they call Him Master or Lord, as if almost they looked upon Him as God. But He bids them shew themselves to the priests, as it follows, And when he saw them, he said, Go, shew yourselves unto the priests. For they were examined whether they were cleansed from their leprosy or not.”
