Dzik, Marek (Instytut Teologiczno-Pastoralny im. św. bpa Józefa Sebastiana Pelczara w Rzeszowie, 2001)
The author tries to find an answer to the question what is the origin and meaning of the sentence „I am the true vine” in Joh 15,1.5. He claims that it comes from the Old Testament. Looking for its roots he separates it in to 2 parts: „I am” and „the true vine”. The first part „I am”, it is a kind of God’s revelation formula which could be found in the different the Old Testament books. The second part „the true vine” it is probably a compilation of the following texts: Iz 5,1-7; Jr 2,21; Ez 17,5-10; 19,10-14. Generally the sentence „I am the true vine” shows Jesus as God Son who gives the disciples the neccesary power to be his followers before the world.
