Grand Prince St Vladimir Examines the Faith (Ivan Eggink, undated (first quarter of the 19th century?))
Of course, this depiction is highly stylised, but, it does symbolise the fact that Grand Prince St Vladimir chose Orthodoxy over Roman Catholicism in 988. Do not forget that St Vladimir consciously rejected both Islam and Roman Catholicism… he was not merely ignorant of them. The former he considered too fanatical (for it forbade liquor) and the latter he found confusing (for his emissaries were not impressed with RC liturgy, finding it irreverent). Orthodoxy both he and his ambassadors found “just right” (“We did not know if we were in heaven or on earth”, in regards to the liturgy at Agia Sofia).
Russia is deeply Orthodox to this day… and shall remain so until the Last Trump, I am sure (Am I Orthodox? Well… I’m Russian… does that answer your question?).
