Gospel of John The Gospel of John is the fourth, and
traditionally last, gospel of the New Testament. Historians
generally agree that it was written between 90 and 100 CE, but
disagree with the assertion of many Christians that the author
was John the Evangelist. According to the United States
Conference of Catholic Bishops: "Critical analysis makes it
difficult to accept the idea that the gospel as it now stands
was written by one person. John 21 seems to have been added
after the gospel was completed; it exhibits a Greek style
somewhat different from that of the rest of the work. The
prologue (John 1:1-18) apparently contains an independent hymn,
subsequently adapted to serve as a preface to the gospel. Within
the gospel itself there are also some inconsistencies, e.g.,
there are two endings of Jesus' discourse in the upper room
(John 14:31; 18:1). To solve these problems, scholars have
proposed various rearrangements that would produce a smoother
order. (http://www.usccb.org/nab/bible/john/intro.htm)" John
