John Chrysostom
Catena Aurea · Lukasevangelium 9
And it came to pass, that, as they went in the way, a certain man said unto him, Lord, I will follow thee whithersoever thou goest. And Jesus said unto him, Foxes have holes, and birds of the air have nests; but the Son of man hath not where to lay his head. And he said unto another, Follow me. But he said, Lord, suffer me first to go and bury my father. Jesus said unto him, Let the dead bury their dead; but go thou and preach the kingdom of God. And another also said, Lord, I will follow thee; but let me first go bid them farewell, which are at home at my house. And Jesus said unto him, No man, having put his hand to the plough, and looking back, is fit for the kingdom of God. It follows, And Jesus says to him, The foxes have holes, &c.
(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.
