Augustine of Hippo
Catena Aurea · Lukasevangelium 14
For which of you, intending to build a tower, sitteth not down first, and counteth the cost, whether he have sufficient to finish it? Lest haply, after he hath laid the foundation, and is not able to finish it, all that behold it begin to mock him, Saying, This man began to build, and was not able to finish. Or what king, going to make war against another king, sitteth not down first, and consulteth whether he be able with ten thousand to meet him that cometh against him with twenty thousand? Or else, while the other is yet a great way off, he sendeth an ambassage, and desireth conditions of peace. So likewise, whosoever he be of you that for-saketh not all that he hath, he cannot be my disciple.
Now to what these comparisons refer, He on the same occasion sufficiently explained, when he said, So likewise whosoever he be of you that forsaketh not all that he hath, he cannot be my disciple. The cost therefore of building the tower, and the strength of the ten thousand against the king who has twenty thousand, mean nothing else than that each one should forsake all that he hath. The foregoing introduction tallies then with the final conclusion. For in the saying that a man forsakes all that he hath, is contained also that he hates his father and mother, his wife and children, brothers and sisters, yea and his own wife also. For all these things are a man’s own, which entangle him, and hinder him from obtainingnot those particular possessions which will pass away with time, but those common blessings which will abide for ever.
