The struggle between the Greek and Latin Churches, hushed for awhile,
broke out again fiercely A.D. 1053, and in 1054 Rome excommunicated
Constantinople, and Constantinople excommunicated Rome. The disputes as

Paterini and the Cathari, in France as the Albigenses, Bulgarians, or
Publicans. The Council of Orleans condemned them to be burned alive, and
many perished.


CENTURY XII.


The wars which spread Christianity were not yet entirely over, but we
only hear of them now on the outskirts, so to speak, of Europe, except
where some tribes apostatized now and then, and were brought back to the
true faith by the sword. The struggles between the popes and the more

Fresh heresies spread during this century, and we everywhere met with
one corrective--death. Most of them appear to have grown out of the old
