The Dead Sea scrolls fill a hole of information affecting the centuries surrounding the change of era, when Judaism took shape and Christianity was born. They present very diverse Judaisms or groups and cults that cohabited and identified themselves as Jews, with a range that made possible the apparition of new movements like the Judaeo-Christian. The impact of the discovery in Qumran in the general public has been disproportionally focused in the possible relations between these new texts and the New Testament, in reference to John the Baptist, to the messianism of Jesus and the title "son of God", to the dualism of John's gospel, or to the "works of Law" by Paul. We will present the specific contact points among the Qumran texts and the gospels, as well as the reading perspectives by the Jew scholars of the foundational texts of early Christianity, specifically around the figure of Logos, Memrá or Aρχή. In opposition to the view of Judaism and Christianity being two religions separated in a first moment without any contact between them, these discoveries highlight the maintenance of transfers between one and the other along the centuries in which Jews and Christians forged their identity, without neglecting the the incorporation of elements from other religions of the ancient world, coming from Iran, Babylon, Egypt, Greece and Rome.
