the greeks and romans did not teach the slavs christianity-thats a lie--the bulgars were christian before boris khan----boris khan made the south bulgars into greek byzantine christians--it was not easy---there was fighting long ago and there is fighting today also------the slavs were christians before the romans and greeks--before the catholic and orthodox church go to them--this is the sdame with the history of albaniaks ----when the turks invaded europe---the bosniaks and albaniaks and other people who resisted the catholic and orthodox forces--turned to islam for help-and in islam they found one god and jesus as a man same like the old true way of christianity-
