Christian Heresies: Johannites

The Johannites were a Gnostic sect which said that John the Baptist, instead of Jesus Christ, was the saviour of mankind.  They are survived in the modern day by the Mandaeans, a dualistic sect scattered from Iraq by the 2003 Iraq war.  Before the war they numbered about 70,000 in Iraq, now about 5000 remain.  The rest are primarily now in Jordan and Syria.
