Cyril of Alexandria — as excerpted in the Catena Aurea on Luke 13:22-30

“Now our Lord does not seem to satisfy him who asked whether there are few that be saved, when He declares the way by which man may become righteous. But it must be observed, that it was our Saviour’s custom to answer those who asked Him, not according as they might judge right, as often as they put to Him useless questions, but with regard to what might be profitable to His hearers. And what advantage would it have been to His hearers to know whether there should be many or few who would be saved. But it was more necessary to know the way by which man may come to salvation. Purposely then He says nothing in answer to the idle question, but turns His discourse to a more important subject.”
