Two layers

The Book of Isaiah contains a sentence which says that "I can not see it, I can not understand it even if I hear it". Both Matthew and Luke quoted this. This part of Isaiah can not be taken in such a way that God darkens a person's mind and makes it impossible to understand God. Rather, it does not mean that humans will or may not know, despite all efforts from God. God can not be distinguished by man. Even if you are a stubborn person who does not want to know at all with a sense of animosity against yourself, you preach the gospel with a great deal of preaching to preach the life of Christ, no matter how serious your heart is, strive for I could not hear him, it was painful. The Lord still does not give up, and calls to the end. God's feelings of saving the person somehow even if it is useless even if it speaks directly at least even if the parable is shown.

Two layers

There are also two layers in the parable. The direct story of the Lord Jesus, and the change in form and meaning of the disciples in the faith given by experiencing the Lord's resurrection. Jeremias and others are not in the form of later disciples' days, and it is more important for Jesus Christ to figure out the parable as it was spoken and its meaning first. This original thing might be able to figure out somehow considering the concrete appearance and circumstances when it was spoken. Christ have prepared a few parables, and I do not think that lord properly selected one of them to be a story. It seems that they talked to each other according to the time and place partner.
This is roughly the theory of Jeremias. It is difficult to decide whether it was really as it is. However, it seems to be true that there are two layers in the parable. How far can we be divided into two clearly?

But even then, it is important to think about the original meaning that Christ made to the story. But here too, one must avoid something like extreme purism. God's revelation, just Jesus. It is only a narrow, wrong idea that it is limited only to what is directly said and done by Christ, and the interpretation that the Early Church added later has nothing to do with the revelation of God at all. If you think this way, even if it is parable, it is only the fact that Christ made it a story, it is not the revelation of God. But this is a misunderstanding. According to Biblical studies, in the gospel it is in the words of the Lord Jesus, but not really, the early church newly created for preaching, and the new interpretation of the old ones It is said that there is something that has been reworked. If this is true, can we say that later things have nothing to do with the revelation of God and are extra things?
