The Fourth Lateran Council in 1215 proclaimed the doctrine of
transubstantiation: that the host wafer miraculously turns into the body
of
Jesus during the mass. Soon rumors spread that Jews were stealing the
sacred
wafers and stabbing or driving nails through them to crucify Jesus
again.
Reports said that the pierced host bled, cried out, or emitted spirits.
On this
charge, Jews were burned at the stake in 1243 in Belitz, Germany -- the
first of
many killings that continued into the 1800s. To avenge the tortured
host, the
German knight Rindfliesch led a brigade in 1298 that exterminated 146
defenseless Jewish communities in six months.
