John's Chapter XXI, which, as has been said, appears clearly to have been a later addition to the original Gospel, relates an appearance of Jesus in Galilee, which is materially different from that of Matthew. The appearance is not on a mountain, but on the shores of the sea of Tiberias, and, instead of the eleven apostles being present, there were, at most, only seven, including Nathaniel of Cana (John XXI:2). All of them have considerable trouble in recognizing Jesus (John XXI:4, 12). Nothing is said by Jesus about baptizing, or preaching to, the Gentiles, but, on the contrary, Jesus tells Peter to feed "my sheep," or "my lambs" (John XXI:15, 16, 17). Nothing is said about any ascension of Jesus into heaven. The Gospels of Mark and Luke, the original Gospel of John, and the Acts, all agree in fixing the after-death appearances and ascension of Jesus in Jerusalem or its neighborhood (Luke XXIV:50; Acts I:12). Apparently the apostles remained for some time in Jerusalem after the Crucifixion (possibly for forty days, Acts I:3; II:1), until they separated and "went forth and preached everywhere" (Mark XVI:20). In the Acts it is said that Jesus "commanded" them to remain in Jerusalem, until the gift of the Holy Ghost should be sent to them (Acts I:4). It is evident, in all these accounts, that the apostles had never understood, or had entirely forgotten, the predictions of Jesus in His lifetime that He would rise from the dead (Matt. XVI:21; XVII:23; XX:19; Mark VIII:31; IX:31; X:34; Luke IX:22; XVIII:33). They were not expecting any resurrection. They were not waiting at the tomb for it to occur, and, by the unanimous testimony of all the writers, they showed the greatest surprise and incredulity at the first reports of Jesus' appearance alive (Matt. XXVIII:17; Mark XVI:11, 13; Luke XXIV:11, 16, 37, 41; John XX:9, 14, 25). Furthermore, it is also evident that Jesus, in these appearances, must have assumed some form or shape different from His natural earthly body. Otherwise His intimate friends and associates could not have been in such uncertainty about recognizing His identity. Thus Matthew says that when He appeared to the eleven "some doubted." But if He had appeared in His natural form, how could any of the apostles have doubted as to whether the apparition was He or some other person? According to Mark, the apostles questioned the accuracy of the report by Mary and the two disciples that they had seen Jesus (Mark XVI:13, 14).
