Luke 8:11

(Hom. 44. in Matt.) And to sum up many things in a few words. Some indeed as careless hearers, some as weak, but others as the very slaves of pleasure and worldly things, hold aloof from what is good. The order of the way side, the rock, and the thorns is well, for we have first need of recollection and caution, next of fortitude, and then of contempt of things present. He therefore places the good ground in opposition to the way, the rock, and the thorns. But that on the good ground are they, which in an honest and good heart, having heard the word, keep it, &c. For they who are on the way side keep not the word, but the devil takes away their seed. But they who are on the rock sustain not patiently the assaults of temptation through weakness. But they who are among thorns bear no fruit, but are choked.

The seed is the Word of God. Those on the way are they who have heard. Afterwards, the devil comes and takes away the Word from their heart, that they may not believe and be saved. We see in a moment that the hardness of the ground causes the seed on the pathways to be snatched away. A pathway always is hard and untilled, because it is exposed to every one's feet. It does not admit any seed into it, but it lies rather upon the surface, ready for any birds that will to snatch it away.

Now this is the parable. After the parabolic instruction in hidden mysteries has been set forth, the second part of the chapter follows, in which the apostolic instruction in open discourses is described. Now this part has two sections, in the first of which they …

The reading of the holy Gospel which you have just heard, dearest brothers, does not need exposition, but exhortation. For human frailty does not presume to examine what Truth itself has expounded. But there is something you ought carefully to consider in this very exposition of the Lord: that if we were to tell you that the seed signifies the word, the field the world, the birds demons, the thorns riches, your mind would perhaps hesitate to believe us. Hence the same Lord deigned to expound through himself what he was saying, so that you might learn to seek the meanings of things even in those matters which he did not wish to explain through himself. Therefore by expounding what he said, he made it known that he was speaking figuratively, so that he might make you certain when our frailty opened up to you the figures of his words. The words of the Lord which you perceive with your ears, retain in your mind. For the word of God is food for the mind. And just as food taken in is rejected when the stomach is weak, so a word that is heard is not retained in the belly of memory. But whoever does not retain nourishment, his life is surely despaired of. Therefore fear the danger of eternal death, if you receive the food of holy exhortation but do not keep in memory the words of life, that is, the nourishment of righteousness. Behold, everything you do passes away, and to the final judgment, without any intervening moment, you hasten daily, whether willing or unwilling. Why then is what must be left behind loved? Why is that to which we are heading neglected?

(in Hom. 15 in Ev.) But our Lord condescended to explain what He said, that we might know how to seek for explanation in those things which He is unwilling to explain through Himself. For it follows, Now the parable is this: The seed is the word of God.
