Orthodoxy.....Catholicism..................................Protestanti sm is more accurate.
Orthodoxy - ascetic, traditional, rigid, internally divided, always losing the focus on earthly, material aspects, hence poverty compared to the other two, emphasis on doctrine, poverty led to possible loss of believers, laissez fair attitude when it comes to private lives of the believers and their pagan histories, faithful to foundations of Christianity when it comes to doctrine and poverty. Inert. Mysticism.
Catholicism - lesson learned from losing strategy of Orthodoxy, rich, firm hierarchy, not allowing internal divisions, early Christian doctrine slightly adjusted, importance of resources understood, taxing its believers regularly, autocratic leadership, pompous, scaring and attracting with its impressive visual aspects, more active, missionaries christianization of distant populations, overarching the national borders, regulating the lives of the believers more thoroughly, wiser than Orthodoxy, I have to admit also beautiful
Protestantism - protest against taxing and firm hand that evolved to religion, modern, in accordance with accumulation of capital, pragmatical in all possible ways, regulating lives of the believers wiser than Catholicism, emphasis on pragmatic aspects of the company. Permissive in doctrine interpretations, allowing branching as long the that link to economy is not violated. Successful, young, related more to everyday life. Democratic leadership if that term could be used for Church.
that is how one average Serb atheists sees those three.
Spiritually somewhere between the two.
Roman Catholic Church is a part of CATHOLIC (all embracing ) Church , together with 23 Orthodox or Eastern catholic churches. Orthodox Churches see pope as a head ranked the same as patriarchs of other Eastern churches.
Catholic Church insists, sadly wrongly ;) on its continuity with early Christianity. Orthodoxy looks stupidly poor so I am guessing roots are there to be found ;)
Protestantism is not recognized within those limits.
I personally have nothing against any of three. I see all of them as companies, firms. First two are founded 2 millenniums ago as unlimited companies, the third one is younger, flexible, so it is Public LTD ;))
