Stories circulated within 5-10 years of Jesus' crucifixion. Those stories remained oral until they were written down, probably beginning about 30 years following the crucifixion, and continuing until about 95 c.e. That doesn't constitute "hundreds of years." There is little evidence that their beliefs were "politically-charged," other than as anathema to oppression.

No, it isn't "heavily debated." John's was written around 100 c.e., not 200 c.e.Where are you getting this information?
Really?
Most scholars agree on a range of 90100 for when the gospel was written, though dates as early as the 60s or as late as the 140s have been advanced by a small number of scholars. The writings of Justin Martyr use language very similar to that found in the gospel of John, which would also support that the Gospel was in existence by at least the
middle of the second century, and the Rylands Library Papyrus p.52, which records a fragment of this gospel, is usually dated to the
first half of the second century.
The Dead Sea Scrolls have suggested an early Jewish origin, "The parallels and similarities to the Essene Scroll, Rule of the Community, in fact, are so numerous and conclusive that they
seriously challenge the theory that the Gospel of John was the latest to be written and that it shows marked Greek influence."

The traditional view is supported by reference to the statement of Clement of Alexandria that John wrote to supplement the accounts found in the other gospels. This would place the writing of John's gospel sufficiently
after the writing of the synoptics.
