Now the parable is this: The seed is the word of God.
All Commentaries on Luke 8:11 Go To Luke 8
Cyril of Alexandria
AD 444
Let us consider those others of whom Christ said, “And those upon the rock are they who, when they hear, receive the word with joy, and they have no root. These believe for a while and in time of temptation depart away.” There are men whose faith has not been proved. They depend simply on words and do not apply their minds to examining the mystery. Their piety is sapless and without root. When they enter the churches, they feel pleasure often in seeing so many assembled. They joyfully receive instruction in the mysteries from him whose business it is to teach and laud him with praises. They do this without discretion or judgment, but with unpurified wills. When they go out of the churches, at once they forget the sacred doctrines and go about in their customary course, not having stored up within themselves any thing for their future benefit. If the affairs of Christians go on peacefully and no trial disturbs them, even then they scarcely maintain the faith, and that, so to speak, in a confused and tottering state. When persecution troubles them and the enemies of the truth attack the churches of the Savior, their heart does not love the battle, and their mind throws away the shield and flees.
