John Chrysostom — as excerpted in the Catena Aurea on Matthew 10:5-8

“Behold the greatness of their ministry, behold the dignity of the Apostles. They are not to preach of any thing that can be an object of sense, as Moses and the Prophets did; but things new and unlooked for; those preached earthly goods, but these the kingdom of heaven and all the goods that are there.”
