The East West Schism.
“The East West Schism.”
1054. Almost no impact on the modern world since most of the Orthodox world was culturally retarded by Islamic domination or other examples of eastern despotism (e.g. Tsarist Russia). The simple fact is that the Orthodox world was east of Poland and that part of the world (at least the Christian part of it) had almost zero influence on the shaping of the modern world from a Christian or secular point of view. In essence, they didn’t show up until 1917 and that cannot be called “the Christian part of it” but Bolshevism.
It is remarkable how little Protestant know and understand about history.
