Church Fathers on Luke 8:4

That which David had foretold in the person of Christ, I will open my mouth in parables, the Lord here fulfills; as it is said, And when much people were gathered together, and were come to him out of every city, he spoke by a parable. But the Lord speaks by a parable, first indeed that He may make His hearers more attentive. For men were accustomed to exercise their minds on dark sayings, and to despise what was plain; and next, that the unworthy might not receive what was…

And therefore it is significantly said, When much people were gathered together, and were come to him out of every city. For not many but few there are who walk the strait road, and find the way which leads to life. Hence Matthew says, that He taught without the house by parables, but within the house explained the parable to His disciples.

Now Christ most fitly puts forth His first parable to the multitude not only of those who then stood by, but of those also who were to come after them, inducing them to listen to His words, saying, A sower went out to sow his seed.
