John Chrysostom — as excerpted in the Catena Aurea on Luke 9:57-62

“(Hom. 27. in Matt.) But what more necessary than the burial of his father, what more easy, seeing that there would not be much time given to it? We are then hereby taught that it becomes us not to spend even the slightest portion of our time in vain, although we have a thousand things to compel us, nay to prefer spiritual things to even our greatest necessities. For the devil watchfully presses close upon us, wishing to find any opening, and if he causes a slight negligence, he ends in producing a great weakness.”
