Janowa formuła wyznania wiary utrwalona w epilogu (20,30-31) i jej ekspozycja w świadectwie Jana Chrzciciela o Jezusie (J 1,19-34)

Because 20:30-31 pulls together John’s themes of witness, faith, and signs so fully, it is best to regard this conclusion as a point of departure for analyzing of the phenomenon of faith and bearing witness to Jesus. W 1:19-28 John negatively testifies that he himself is not the eschatological king, Elijah, or the Mosaic pro-phet, but that one whose slave he was not worthy to be was already among them. In 1:29-34, he positively testifies that Jesus in the lamb, and he recognized his identity as Son of God (1:34) and Spirit-bringer (1:33) because the Spirit was on Jesus (1:32-33). The “next day” provides a transition to a new christological con-fession to John’s disciples. In view of Gospel’s penchant for double entendre, that the Baptist saw Jesus “coming” (ἐρχόμενον) to him (1:29) may suggest a narrative confirmation of the one “coming” (ἐρχόμενος) after John (1:27).
