Why does the Last Supper in the Gospel of St. John (13-17) contain no words of consecration?

To answer the title question of this article – Why does the Last Supper in the Gospel of St. John (13-17) contain no words of consecration? – one will mainly show that the Gospel of St. John has a six-element literary structure, the same as the Book of Exodus 1-18 has. This first step bases on the analyses of many exegetes and also on the particular comparative counting of numbers of words in all pericopes of four Gospels, which one performed in this paper. Then one will show four consecutive stages of Jesus’ life – presented by four consecutive pericopes of Jn 1:19-20:31 – as His four-stages Exodus from this world to eternity. Based on the thesis proved in the earlier papers (see for example: https://www.adoracja.bielsko.opoka.org.pl/praca_doktorska/USAProphetsM.html) that Ex 1-18 is the six-element treaty of the four-step covenant-making ceremony performed by God and Israel, one will show the whole life of Jesus on the earth as analogical to the Exodus described in Ex 6:2-15:21 – as performing consecutive four elements of the ceremony of making the New Covenant. It means John’s Gospel is the six-element treaty of the New Covenant. The key statement shows that The Pericope of Passion and Death (Jn 18-19) describes the irrevocable Jesus’ act of covenant-concluding, done through His passage between the darknesses of the Abyss-Death. It is analogical to pericope Ex 13:17-14:31 as a description of the irrevocable act of covenant-concluding by the passage of God and Israel between the waters of the Abyss-Red Sea. Thanks to these observations, one will get to know the answer to the question stated in the paper’s title.
