Feste, lezionari giudaici e quarto vangelo,

Have judaic festivities and the synagogal lectionary taken any role in the formation and the organization of the Fourth Gospel? This study tries to give an answer, starting from the researches on the judaic lectionary that have supposed its direct influence on the formation of the New Testament. The surveys into the judaic worship and into the Synagogue history reveal the complexity of this hypothesis. Actually it doesn't exist the evidence of the existense, during the I century C.E., of an established, annual or triennal, lectionary. Even if one can appreciate a possible influence of the judaic liturgy on the first christian communities worship, it is essential to open the door to other hypothesis, such as the existence of scriptural testimonia, a better adhesion to Jesus's historical realty or the probable sacerdotal background of the fourth evangelist
