In the Eastern Orthodox Church (EOC) the word for sin in Greek is "αμαρτία" which is defined in the following way: 'failure' or — more specifically — 'missing the mark,' 'going astray,' 'erring,' 'severing a relationship,' or, ultimately, “failing to achieve the purpose and benefit of life for which one is created.'
There were incidents of Roman emperors, Russian tzars and Byzantine emperors who have done things “in the name of the church” that were motivated by economic or political circumstances and the church spoke out against them, however not in every situation.
